The best Kaplan Qbank alternatives for USMLE in 2026

Short answer: The best Kaplan Qbank alternative for most students is Argonaut: $48 once covers Step 1 and Step 2 CK with no expiry, where Kaplan sells each exam separately, from $199 for Step 1 and $159 for Step 2 CK. Argonaut's questions are written to the NBME Item-Writing Guide and approved by a clinician, and ARGO chooses your next session for you instead of leaving you to build quizzes. UWorld, USMLE-Rx and AMBOSS are the other main options.

To be fair

What Kaplan still does best

  • Two full-length practice tests with each Qbank.
  • A 7-day free trial, the longest of the paid banks here.
  • Questions link to Kaplan's Lecture Notes books.

Stay with Kaplan if you want full-length practice tests bundled with your Qbank, or you already use Kaplan's Lecture Notes.

Switching

How to switch from Kaplan

  1. Try before you pay. Answer a block of free Step 1 or Step 2 CK questions and compare the vignettes and explanations with Kaplan's.
  2. Keep your notes. Your error log and flashcards move with you; the review method in how to review USMLE questions works in any bank.
  3. Let ARGO find your gaps. Your first sessions scout the high-weight systems; after a few hundred answers ARGO targets your weakest topics directly.
  4. Or run both. If your Kaplan access hasn't run out, use Argonaut as a second bank for fresh questions on the topics you keep missing.

Questions people ask

01What is the best alternative to the Kaplan Qbank?

For most students, Argonaut: $48 once for Step 1 and Step 2 CK, with no expiry and ARGO adaptive sessions. UWorld is the largest bank if budget isn't a concern; USMLE-Rx covers both exams for $299 a year.

02Is there a cheaper alternative to Kaplan for USMLE?

Yes. Argonaut is $48 once for both exams. Kaplan lists its Step 1 Qbank from $199 and its Step 2 CK Qbank from $159, sold separately.

03Is there a free alternative to the Kaplan Qbank?

Partly. Argonaut has 113 free questions with full explanations and 73 free Library chapters, with no account and no time limit. The USMLE program also publishes free sample test questions on usmle.org. Kaplan itself offers a 7-day free trial.

04Is Kaplan good for Step 1?

Kaplan advertises 3,200+ Step 1 questions, two full-length practice tests and progress reports. It's a solid bank; the trade-offs are a separate purchase for Step 2 CK and quizzes you build yourself rather than sessions chosen for you.

05Does Argonaut include practice tests like Kaplan?

No. Argonaut has timed 20-question blocks in the 2026 exam format but no full-length self-assessments. Pair it with the NBME's official self-assessments, which most students use to check their readiness.
