FAQ

Questions, answered.

How do I get access?
Pick Step 1 or Step 2 CK, choose a plan, and you get full access to that QBank immediately after checkout — every question with its full teaching explanation.
How many questions are in each QBank?
Step 1 has 4,000 exam-style questions across every discipline — pathology, physiology, pharmacology, biochemistry, microbiology, immunology, anatomy & embryology, and behavioral science. Step 2 CK has 2,390+ clinical vignette questions across 23 systems. Every question includes a full teaching explanation.
Is this a subscription?
The Step 1 QBank is a one-time purchase for a fixed access window — 1, 3, 6, or 12 months ($29–$119) — with no auto-renewal. The Step 2 CK QBank is billed monthly at $29 and you can cancel any time.
What is spaced-repetition review?
Every Step 1 question you miss becomes a review card. Get it right and it comes back later on a widening schedule (1 → 3 → 7 → 16 → 35 days); miss it and it returns the next day — so you spend your time on exactly the material you haven't locked in yet.
Are the questions really exam-style?
Yes. Every question is written in NBME-style clinical vignette format with full explanations that teach the reasoning behind each answer, including why each distractor is wrong.
Can I study on my phone?
Absolutely. The QBanks and MatchPlan are fully responsive, so you can practice questions and update your plan from any device.
Can I see the questions before I buy?
Yes — answer the sample question near the top of this page. Every question in the bank is written and explained the same way, so you know exactly what you're getting.
