Frequently Asked Questions

How do the different plans benefit students? 

Each plan is tailored to a specific discipline’s learning needs. Some plans are aligned to medical or nursing education, others to healthcare professional development, with each plan’s unique content designed to deliver the best learning experience possible for that field of study.


What package should I choose?
Choose the package that aligns with the current stage in your medical school journey. For example, we suggest the Basic Sciences library for medical students preparing for the COMLEX USA® Level 1 exam when clinical reasoning isn't part of the curriculum. Typically this is Year 1 or 2, but depends on your program. If you're headed into clerkships, or clinical reasoning is incorporated earlier in your program, we recommend the Osmosis Suite.

Can I switch plans whenever I want? 

Yes, you can! Switching plans is easy. To change plans go to and click on “change package” under Billing Details.


Why are some features not available in the Clinical Sciences package?

Some features are not available in the Clinical Sciences package because they’re specific to the Basic Sciences library. Purchase the Osmosis Suite to get access to the full library.


What else is included in my membership?
You will get round-the-clock customer support in case you have questions. With all packages you can explore additional content like Core Competencies which includes professionalism, interpersonal and communication skills in addition to Featured Series like learning science and self-care.
