Introduction

No doubt that since you got into medical school, or even before you started medical school, you’ve heard how important the USMLE Step 1 Exam is. This is the first board exam you’ll be taking on your journey to becoming a full-fledged physician—and the stakes are high.

Until recently, your score had a huge influence on what your residency, specialty, and overall career options could be in the future. In fact, 94% of program directors stated that a candidate’s score on USMLE Step 1/COMLEX-USA® Level 1 was the most important factor when offering a prospective residency interview.

With USMLE Step 1 moving to pass/fail, less emphasis will be placed on this exam; instead, program directors will likely be more focused on things like your USMLE Step 2 CK score and performance during your clerkships.

Nevertheless, passing Step 1 is essential if you want to continue learning medicine, and for now, it remains the most high-pressure exam you’ll take on the road to residency.

No big deal, right?

Well, take it from us: you’re completely capable of passing this exam and getting a high score. You are a medical student: you’ve come this far and with the right plan you’ll make it all the way. Osmosis has your back!

In this guide we’ll be covering everything (and we mean everything) about USMLE Step 1, including:

  • What’s covered on Step 1?
  • How should I study for Step 1?
  • How do I apply to take Step 1?
  • When and where should I take Step 1?
  • What Step 1 score do I need to match for residency?
  • What happens if I fail Step 1?
  • How has COVID-19 impacted Step 1?
  • How do students use Osmosis to study for Step 1?
Now, without further ado, let’s get started with the most fundamental question to help you prepare for Step 1: What’s on the USMLE Step 1 exam?

What’s on the USMLE Step 1 exam?

Step 1 is a multiple-choice computerized test that you’ll take at a designated exam center. The exam is divided into seven “blocks,” each containing up to 40 questions that will test your medical knowledge and your analytical skills. You will have one hour to complete each “block.”

What skills will the Step 1 exam test me on?

In general, USMLE Step 1 will require you to:

  • Utilize your understanding of basic scientific principles to solve clinical problems
  • Analyze and interpret data (graphs, tables, oscillation media, etc.)
  • Recognize both normal and pathological processes from gross and microscopic specimens.

What topics are covered on Step 1?

USMLE Step 1 covers a range of didactic topics, and evaluates you on a series of physician tasks and competencies as well:

What score do I need to pass Step 1?

On February 12, 2020, the NRMP announced that scoring for USMLE Step 1 will be changed to pass/fail. The transition from numeric scoring to pass/fail began with exams taken on or after January 26, 2022. To learn more, visit USMLE.org.

How long is the Step 1 exam?

The whole Step 1 exam takes about 8 hours, broken down as follows:

  • Tutorial: 15 minutes (optional—more on that later)
  • Breaks: 45 minutes
  • 7 Testing blocks: 60 minutes per block (~1.5 minutes per question)
There are some nuances around breaks that we’ll cover in more detail in the Step 1 Logistics section later in this article.

What's the best way to study for USMLE Step 1?

Now that you have a sense of what you’re going to be tested on, it’s time to come up with a strategy for how you’re going to learn all this information for the exam.

Studying for Step 1 isn’t like studying for any other exam you’ve taken. You need to know two years’ worth of medical school information inside and out. Solidifying your knowledge of this gargantuan amount of complex information requires a game plan.

1. Develop effective learning habits

Learning is a science, and there are many proven techniques that will make your life a whole lot easier in the lead-up to Step 1. Osmosis Research Director Dr. Sean Tackett developed a full course on learning science. How to Learn in Medical School helps students become better learners using six proven learning science techniques:

  1. Testing effect
  2. Spaced repetition
  3. Interleaving
  4. Multimedia learning
  5. Elaborative interrogation
  6. Concrete examples

A little note on Spaced Repetition

Spaced repetition is a big part of why learning by Osmosis is so effective. But what is spaced repetition and how does it work?

Spaced repetition is the act of retrieving knowledge at increasing intervals to reduce forgetting and enhance long-term learning. Essentially, you’re reviewing information repeatedly over time to burn it into your long-term memory.

Timing this manually can be difficult, which is why technology-enhanced learning is so effective. The Osmosis platform uses a spaced repetition algorithm to test you on key information at optimal times to aid memory retrieval and help you build a knowledge foundation that will last for a lifetime.

2. Pick a few good resources and stick to them

There’s a glut of study resources out there for Step 1 and it can be tough to find the right fit. Some students will oversaturate themselves with resources—this trial and error process can mean a lot of wasted time early in the study period. So how do you choose?

The UFAP study resources (UWorld®, First Aid®, Pathoma®) are great, but UFAPO—combining the resources with Osmosis—is even better. Think of Osmosis as your HQ and right-hand-person for this momentous challenge ahead of you. All of the UFAP resources can be integrated into the Osmosis Study Schedule for a completely seamless learning experience that covers all of your bases.

With Osmosis, you’ll also have the additional support of our extensive video library, which brings to life the topics covered in First Aid and UWorld’s question explanations—allowing you to have a better grasp of the material and be more confident on the day of your Step 1 exam.

These videos cover important topics like basic sciences, biostatistics, epidemiology, pharmacology, microbiology, pathology, physiology, and more. Once you’ve watched the pathology videos, you can kick your studying into high gear with our new High Yield Pathology series, which has been specifically designed to highlight all of the important concepts needed for the USMLE Step 1.

Additionally, Osmosis also has flashcards, questions, and High-Yield Notes that can further assist you in your mastery of your preclinical knowledge.

Every learner will take a different approach with regard to how they use these resources. In our next section, we’ll go over some general tips to steer you on the right path.

Osmosis illustration of a student reviewing the material.

Start reviewing early

The sooner you start studying for Step 1, the better. You should be regularly reviewing concepts you’ve already learned throughout the year to ingrain them into your long-term memory. This will save you time during your dedicated study period, as you’ll already be building on a strong base of knowledge.

Some students like to start studying very early on, and take a practice exam before their dedicated study period begins. NBME self-assessments will highlight your weak areas, giving you a better idea of where you should focus your studying.

Go through each resource as many times as you need

A quick Google search will reveal endless Step 1 prep strategies from students—you have to pick what’s right for you. A general rule for knowing if you’ve studied a topic enough is to try explaining the concepts to someone. If the information comes easily, you’ve learned it; if you find yourself struggling, you still have work to do.

Focus on classical presentations of diseases

When you’re studying pathology for the exam, focus specifically on the typical presentations of diseases, as the exam will only test you on these. If you try to think about all the possible ways a condition can manifest, you will end up overthinking things and potentially trip yourself up. Familiarize yourself with the basics and trust your gut.

Stop studying when you feel you’re running out of steam

If you’ve been studying for over 10 hours and feel like things just aren’t sticking anymore, chances are, they aren’t. You might have a classmate flexing about pulling regular all-night sessions, but you don’t know how much of that time is actually productive.

Some students feel “guilty” taking study breaks. If it helps, consider breaking up your study periods with other “productive” activities, like exercise or meal prep. Whatever you do, step away from the books, and close your computer—you need this time to absorb the knowledge you’re trying to retain. It’s all part of the process!

Don’t panic if you see a classmate using a resource you’re not using 

As we’ve mentioned already, everyone will take a slightly different approach to learn for Step 1. Find the resources that work for you, and stick with them.

3. Learn how to break down USMLE-style practice questions

Knowing your systems and processes inside and out is just one aspect of studying for Step 1. You’ll also need to be familiar with how USMLE® questions are structured so you can quickly eliminate incorrect answer options and make the best choice.

Osmosis has several resources that show you how to develop the right mindset to ace Step 1 questions:

When you’re done with these resources, try putting your learnings into action with the Osmosis Q-Bank, which contains more than 3,300+ Step 1-style practice questions.

 Get started with the Osmosis Question Bank.

4. Make effective use of flashcards

 Flashcards are a convenient way to learn a high volume of information quickly. They’re best suited for learning individual facts rather than interconnected concepts, and they’re a great way to study on-the-go.

Osmosis Prime has over 16,500 flashcards built into the platform, many of which are derived from Brosencephalon’s Anki deck, all containing information you may need to know for Step 1. If you’re using Anki, you can integrate your decks into the Osmosis learning platform. An added bonus: Osmosis automatically works spaced repetition into your flashcard queue, delivering a method for reviewing concepts that’s based in learning science.

You can also build your own flashcard decks on Osmosis using the Flashcard Builder. Not sure where to start? Osmosis learner Jason Lundy wrote a fantastic article on Writing Great Flashcards.

5. Practice multimedia learning

Multimedia learning is when you incorporate written, visual, and audio materials into your learning. This is the essence of learning by Osmosis!

When you learn from a variety of sensory stimuli, that information is processed into smaller “bits” which become part of your working memory. Combining the words you read and listen to with visual images helps your working memory process them together as integrated “chunks” which moves the concepts into your long-term memory more efficiently and forms stronger links with information you’ve already learned.

The Osmosis Learning Loop

Studying for USMLE Step 1 with Osmosis allows you to harness the power of multimedia learning to gain knowledge that will stick with you long after you've taken the exam. Make the most of it using these resources and practice the Osmosis Learning Loop:

Osmosis illustration of the Osmosis Learning Loop.

6. Take practice exams

For a $75 fee, you can visit your local Prometric test center and take a short practice test in the same environment that you’ll take the actual Step 1 exam. These practice tests are shorter than the exam you’ll take on test day, clocking in at around 3.5 hours, but they’re a good way to familiarize yourself with the exam setting. To learn more and register, visit the USMLE website.

Step 1 is a long examination, and you need to go in prepared to deal with what can be a physically and mentally exhausting experience. To get a feel for this, you should try to simulate the test environment with at-home practice tests before you take the exam.

The NBME’s comprehensive self-assessments will help you identify key areas you need to focus on to improve your score. Typically, they’re about 4 hours long—doing two of these back-to-back is gruelling, but good training for test day.

 Learn more about NBME self-assessment services.

A note about NBME practice tests: many students obsess over their practice test scores and cause themselves undue stress. Think of this as a practice run, not an exact predictor of your Step 1 score.

When should I take my Step 1 practice tests? 

Every student will approach practice tests differently. There are a range of approaches, and you should do what works for you. Some students may take a practice test every 2–3 weeks during their dedicated study period, including one at the Prometric test center.

Whatever your approach, try to take a practice test at least a month before the actual exam. This way, if you don’t get a score that is within the range you want, you’ll have time to reevaluate your goals and rethink your strategy with minimal stress.

The Osmosis Step 1 Study Schedule will automatically integrate practice exams into your schedule if you create one during the dedicated period, which ranges from 4-8 weeks from your test date. The platform will pick the optimal days for you to take your practice tests.

Are you a little further out from your test date, or maybe you don’t have a date selected yet but still want to incorporate some practice exams into your schedule? The Step 1 Study Schedule allows you to input these dates manually, along with other resources (question banks, books, and videos).

7. Maintain healthy habits in the lead-up to the big day

Keeping a healthy routine should be part of every study plan. Physical and mental self-care is crucial for thriving in every stage of your medical education, but the months, weeks and days leading up to your first board exam are particularly stressful. Here are a few quick tips for maintaining equilibrium and managing any last-minute exam-day jitters so you feel fully ready to crush Step 1 on test day. And remember: test anxiety is a real (and solvable!) problem that many students face. Check out our two-part webinar on the topic, and always feel empowered to ask for professional help if you need it.

Take study breaks

Taking a break will give your brain time to absorb the information for the long-term. Once you see your productivity levels starting to flag, it's time to step away from the books and do something else, even if it's just for a few minutes. Check out these study tips from Osmosis learners and the team for more information on the value of breaks, plus advice on how to optimize your study space for maximum productivity, and more:

Make sure to exercise

Physical exercise has positive benefits for cognitive performance. It’s also a great way to blow off steam. Osmosis learners Abe Baker (University of Illinois College of Medicine, Rockford) and Percy Takyi (Philadelphia College of Osteopathic Medicine) both watch Osmosis videos while they exercise!

Eat a healthy diet

When it comes to Step 1 studying, ramen noodles aren’t going to cut it. You need to eat real brain food. Eating a healthy, balanced diet of green vegetables, whole grains and lean proteins will keep you alert and focused.

Maintain a regular sleep schedule

Proper sleep hygiene is important. Going to bed at a consistent time every night will keep your brain well-rested, which helps strengthen connections between ideas.

While it might be tempting to sneak in a few flashcards on your phone before bed, try to avoid doing this. Stop studying, switch off, and avoid screens at least an hour before bed.

Establish a support system with friends and family

Maintaining relationships is challenging during medical school, especially during your Step 1 study period, but it’s very important for your mental wellbeing. Whoever you choose to be part of your support network, make sure to stay in regular contact with them. Having someone to cheer you on as you reach towards your goals is incredibly motivating!

Celebrate important study milestones

Studying for Step 1 is like a marathon—you have to pace yourself! And every once in a while, that means taking a study break. Small goals are worth acknowledging, and it really helps to have something to look forward to at the end of a period of dedicated review.

Stop studying the day before the exam

Now, this one might be a little controversial for die-hard USMLE preppers. But hear us out.

Dedicate the day before the exam to getting yourself into the right headspace. Relax, recharge, and take care of last-minute housekeeping tasks, like figuring out how to get to the test center, checking the weather, and preparing your snacks.

And, as a reminder, go to bed on time!

USMLE Step 1 exam logistics: What you need to know for the big day

 Now that you’re familiar with what’s on the USMLE Step 1 exam, how to study for it, and how to mentally and physically prepare for it, it’s time to look at practical details, like registering for and taking the exam.

How do I apply to take Step 1 as a US Student?

To register for the exam you’ll need to visit the NBME® Licensing Examination Services website, input your information, and pay a $645 registration fee. You’ll then need to coordinate with your institution to have your documents sent to the NBME head office for processing.

After you receive your email confirming your three-month testing window, head to the Prometric website to schedule a specific date.

How do I apply to take Step 1 as an International Medical Student?

If you’re an International Medical Student (you attend a medical school outside of the U.S. and Canada), you’ll have to register through the Educational Commission for Foreign Medical Graduates (ECFMG®).

Can I reschedule my Step 1 exam date if I need to?

 Yes. 31 days or more from your scheduled exam date is free, closer to the exam incurs a fee. Get the specifics here.

When should I take Step 1?

U.S. medical students typically take Step 1 in April, at the end of their dedicated study period, but it varies by institution. Some students don’t take it until the third year, when they’re in the midst of clinical rotations!

International students will often take Step 1 during the summer between their preclinical years and the start of clerkship (e.g. the summer after second year in a four-year program), or after fourth year in a six-year program.

Whenever you end up taking Step 1, make sure you give yourself plenty of time for review. Programs vary in their allotted Step 1 dedicated period for students. We do recommend beginning your prep 3-6 months before your exam, but on average, 5-8 weeks (or 40 dedicated days, not including weekends or break days) is the recommended amount of time for a dedicated study period. We’ll also note that these time estimates may shift significantly given the transition to pass/fail for Step 1.”

Where do I take Step 1?

USMLE Step 1 exams take place at Prometric test centers around the country. To find where your nearest test center is, plug your ZIP code into Prometric’s website. COVID-19 impacted Prometric test centers, but as of June, they have reopened for essential tests.

What can I expect on test day?

You need to show up for the exam at least 30 minutes before the scheduled time to check in. If you’re late, you won’t be allowed to take the exam. Bring a government issued ID with a name that matches your scheduling notification.

The exam center will provide you with a temporary locker for your belongings, which you can access during your breaks. You’re not allowed to bring anything into the exam room with you, save for your ID, locker key, and soft earplugs and noise-cancelling headphones provided by the test center.

Items like eyeglasses will be inspected to check for cameras, and all jewelry with the exception of wedding rings is forbidden. Empty your pockets, and prepare to be scanned with a metal detector before entering the exam room.

Osmosis illustration of prohibited items you cannot bring to a Prometric test center.

What is the USMLE Step 1 exam room like?

As we’ve mentioned, USMLE exams typically take place at Prometric test centers, although with COVID-19, temporary test centers have opened up on some campuses. Remote exam proctoring is also being considered.

Osmosis illustration of a student taking the exam remotely.

In a typical scenario, you’ll enter an exam room that looks like an office space. There will be cubicles with individual computers. You’ll be told which is yours before entering the exam room. If you experience issues with your assigned computer, inform staff immediately.

Osmosis illustration of a Prometric test center.

What is the USMLE Step 1 test interface like?

The USMLE Step 1 test interface is pretty simple—you can check out a working version here. We’ve also put together this image highlighting the basic features and their functionality.

Osmosis diagram of the USMLE Step 1 testing interface.

How do breaks work during the USMLE Step 1 exam?

USMLE Step 1 test-takers are entitled to 45 minutes of break time throughout the course of the exam. You can take up to six breaks (i.e. one break between every testing block). You cannot break in the middle of a block.

How you use your break time is up to you. Some test-takers will take a break every block, while others will take a longer break every two blocks. If you finish a block early, you can leave the exam room, and that time will be added onto your break period.

You can also add to your break period by skipping the 15-minute tutorial session at the beginning of the exam. Test-takers can do the tutorial at home before heading to the test center. If you’re familiar with NBME practice exams (and you should be!) or platforms that use a similar interface, like UWorld, you should also be fine to skip the tutorial.

What should I bring with me to the Prometric test center?

Bring a water bottle and some light snacks to eat between test blocks. Avoid a full lunch, as it could make you sleepy. Osmosis’s health and wellness coach, Ishan Dahal, recommends healthy foods that will give you quick energy boosts, like:

Osmosis illustration of a student holding a bowl with: nuts, protein bars, cheese, greek yogurt, fruit, jerky.

(Note: When you leave the exam, don’t forget to bring the slip provided by the test center that proves you took the exam—if anything, it’ll serve as a reminder that the whole experience was real!)

I have a disability. Can the Prometric test center accommodate my needs?

Yes, accommodations can be made for people with physical and learning disabilities, provided the applicant provides full documentation regarding the particularities of their circumstances. You’ll need to fill out an application form and provide a personal statement and copies of professional assessments.

For a full list of what you need to do to get started, visit the USMLE test accommodations page.

What should I expect after I take USMLE Step 1?

When will my Step 1 results arrive?

Results are usually available in 3–4 weeks, but delays do occur. The USMLE says to allow at least eight weeks for notification that your score is available. You can find announcements about any potential delays here. If possible, try to use this time to relax and recharge. You’ve earned it, and at this point, you’ve done everything you can!

Osmosis illustration of a student recahrging in his bed.

What happens if I fail Step 1?

Unfortunately, some students do fail Step 1 (or the other Step exams) each year. It’s not the best of circumstances— even if you score high on a subsequent attempt, the fact that you failed can impact your residency applications, as there are far more applicants than available residency positions.

If you fail Step 1, the first thing you should do is take a deep breath: this isn’t the end of your journey, and it’s going to be okay. Take time to examine and accept your feelings, and then look ahead to the future.

Next, tell your advisor. They will help you come up with a recovery plan, delaying your clinical rotations if necessary, and arranging a second attempt. Remember to thank your advisors for their help!

When you’re studying for Step 1 the second time, assess your previous study strategy and adapt. Avoid spending too long on any one subject, and focus on what you don’t know, rather than topics you’re already confident in. Use practice tests to identify your areas of weakness and double-down on them to build a more well-rounded knowledge base.

Step 1 isn’t the sole measure of your worth as a residency applicant and future doctor. There are other factors, including:

How has COVID-19 impacted Step 1?

The COVID-19 pandemic has understandably had an impact on board exams for all health professionals. Many students have had their exams pushed back or cancelled altogether. Those who are still able to take the exams are doing so in exceptional circumstances, and must take adequate safety precautions.

For a more detailed look at what's going on with Step 1 in light of the pandemic, check out this article.
