Best COMLEX prep in 2026: COMBANK, UWorld, AMBOSS, Lecturio and COMSAE
First checked October 12, 2026; rechecked October 21, 2026 · Sources: each provider’s own pages for prices (AMBOSS question-bank bundles as reported); the NBOME for exam facts and COMSAE. Ratings are our editorial assessment from published details, not hands-on tests.
The best COMLEX prep depends on whether you’re taking the USMLE too. For COMLEX-only students, TrueLearn’s COMBANK is the bank built for the exam, from $339 for 90 days with a Pass Guarantee. If you’re also taking the USMLE, UWorld’s Step 1 bank plus OMT supplement ($479 for 90 days) covers both. AMBOSS suits students who want a library and one bank across exams, and the NBOME’s own COMSAE practice exams cost about $60 each.

How we ranked the best COMLEX prep
We compared what each provider publishes on its own pages (price, COMLEX-specific and OMM content, access and guarantees) and rated each course out of 5 with the same rubric we use across the site: question bank 25%, practice exams 20%, lectures 15%, platform 15%, support 10% and value 15%. The NBOME’s own COMSAE isn’t rated because it’s official practice, not a course. We don’t accept payment for placement and don’t currently earn commissions. See how we rank COMLEX prep.
