The question bank you don’t have to do twice.
Residents answer thousands of practice questions and forget most of them before exam day. Proa is built the other way around: it tracks what you are about to forget and brings it back before you do.
No account, no card. Real questions with full explanations.

Doing the bank twice is not a study plan.
The second pass exists because the first one leaks. You read an excellent explanation in March, you nod, you move on, and by the exam it is gone. That is not a discipline problem. It is what memory does when nothing brings the fact back.
Every other question bank measures what you know today. None of them does anything about what you will still know in eight weeks.
Illustration of the effect, not a measurement.
Answer. Understand. Retain.
Answer
Board-style questions mapped to the official blueprint of your exam, written and reviewed by board-certified physicians. Timed, untimed and tutor modes.
Understand
Every option explained, including why the wrong ones are wrong. Explanations are written to teach the concept, not to defend the answer key.
Retain
The part no other bank does. Every question you miss is scheduled to come back at the point where forgetting is most likely, and the facts that resist memorization come with an encoded version you can hold on to.

A retention engine, not just a score report.
Analytics tell you what you got wrong. Proa does something with it. Every question you miss, and every one you got right without being sure, enters a schedule and comes back at the point where you are most likely to be about to forget it.
The schedule is computed from your own answers, so two residents using the same bank see different questions on the same day.
For what refuses to stick.
Doses, cutoffs, classifications and diagnostic criteria are the first things to go, because there is nothing to understand about them. For each one, Proa gives you a version built with the techniques used in memory competition, where arbitrary material is the whole sport.
You are not asked to invent the mnemonic. It comes with the question.
A plan that assumes you have shifts.
Proa turns your exam date and the hours you actually have into a weekly plan of study blocks, and tracks what you complete. It expects call nights, post-call days and weeks where nothing gets done, because that is the real shape of a residency.
Retrieval sessions are short and land on the days you have. New questions go where you have more.
Same standard of questions. A different idea of what a bank is for.

Based on the public pricing and product pages of the three largest US question banks, September 2026.
Built one exam at a time.
A Proa bank is released only when it covers the official blueprint of its exam in full, with every question reviewed. That is slower than launching thirty half-finished banks, and it is the only way the retention system is worth anything.

It weighs on what we build next, and you will hear first when your bank opens.
One bank. Three durations. Nothing else to buy.
Every plan includes the full question bank, the explanations, the analytics, the retention system and the planner. If it is not for you, you have 30 days to get your money back.
