How to Solve UWorld
The same method that's taken students from 45% to 75% in under four weeks. Four moves, in order: Read, Pre-solve, Solve, Review.
Most students open UWorld on day one, get 40%, and spiral. That's not a UWorld problem — it's a sequence problem. UWorld is a learning and assessment tool, not a first-pass resource. Used correctly, it's the most powerful tool in your prep.
R — Read. Go through First Aid page by page on usmlevault.com (60–70% of UWorld traces straight from FA lines). P — Pre-solve. Before UWorld, hit the same First Aid pages from 3 more angles: the Test Yourself MCQs on every page, the short Mehlman videos that teach you how to rule answers in and out, and Foundation Anki to recall it all actively. S — Solve. Open UWorld by system, not random — now the questions make sense. R — Review. After every block, close every knowledge gap in First Aid before the next block. Repeat system by system.
Before UWorld
You cannot just simply start UWorld. Before opening any system in UWorld, you spend 4 days building the foundation for that system. This is not optional prep — it's what makes UWorld actually work.
First Aid alone is dense and abstract without context. These 4 days give every page a framework before you ever see a clinical scenario. UWorld then becomes recognition, not discovery.
Every step below hits the same First Aid pages for the system — just from a different direction. Read once, a page is familiar. Hit from 4 angles, it is yours.
- 1 · Read it — the First Aid Guide, page by page. You understand the page.
- 2 · Test it — the Test Yourself MCQs at the bottom of every page. You find out, that minute, whether you actually learned it.
- 3 · Think with it — the Mehlman videos for that system. You learn how the exam asks the page: how to rule answers in and rule them out.
- 4 · Recall it — Foundation Anki for that system. You pull every high-yield fact back out of memory, without the page in front of you.
That is why UWorld goes well after this. You are not meeting the system in UWorld — you are proving you already own it. Skip an angle and UWorld finds the hole for you, one wrong answer at a time.
Day-by-Day Prep
Go through First Aid for the system page by page, alongside usmlevault.com. Each page follows this exact sequence:
- Read the Focus On section for that page on the Vault
- Go through the Vault explanation for that page
- Read up on anything you find important or don't understand
- Look at the actual First Aid page — it should now make sense
- Go to the Test Yourself section on the Vault and solve the MCQs
Each page takes roughly 10–12 minutes on average. That's 4–6 pages per hour. There is no system where you cannot read all of First Aid for that system in just two days using this method.
Watch the Mehlman Medical videos for the system you're about to start. These are short videos — about 5 minutes each — not PDFs. Each one takes a high-yield topic and shows you how to think about a USMLE MCQ on it: which clue rules an answer in, which one rules it out, and how to get from the stem to the answer.
You just read those pages in First Aid. Mehlman now shows you how the exam will ask them — so the facts turn into decisions. How to do this is explained in the University section of the Vault — there's a video there that walks you through the exact process. Watch that video first.
This step takes roughly half a day to a full day depending on the system. Do not skip it — Mehlman makes the mechanism layer click in a way that First Aid reading alone doesn't.
Run the Foundation Anki deck for that system only. It follows First Aid page by page, and it makes you actively recall every high-yield fact — not re-read it. Recognising a page and pulling it out of memory are different skills, and UWorld tests the second one.
Anything that makes you hesitate, go back to that First Aid page. By the end of the day, the system's high-yield is sitting in memory, ready for UWorld. The how-to is in the University section of the Vault under "How to do the Foundation Anki."
You've now attacked the system's First Aid from 4 angles: read it with the Vault, tested it with the Test Yourself MCQs, learned how the exam asks it with Mehlman, and recalled it with Foundation Anki. You are not starting UWorld cold. When a UWorld question appears on renal — you know the physiology, the pathology, and the pharmacology. UWorld then tests whether you can apply it clinically. That's a very different experience.
UWorld Setup
Every block you create in UWorld for system-based study should use these exact settings. No exceptions during the learning phase.
Timed mode is for the NBME phase — after you've completed the system. Using timed mode during learning adds cognitive load before you're ready and tanks your score. Stay in untimed tutor mode for all system-based UWorld work.
Per-Question Protocol
Every UWorld question falls into one of three scenarios. The way you handle each one is different. Learn these three scenarios and apply them exactly.
You read the question, thought of an answer, picked it, and the explanation matches your reasoning exactly.
This means you've understood the concept from First Aid. UWorld just confirmed it.
You picked B because of reason XYZ. The answer is B, but the actual reason is ABC. You got lucky — your understanding of the underlying concept was wrong.
This is a knowledge gap, not a correct answer. Treat it the same way you'd treat a wrong answer.
You had no idea what was going on, picked something, and it was wrong. Or you had partial knowledge but landed on the wrong answer.
This is completely normal, especially in the first system. Do not spiral. Getting things wrong in UWorld is the mechanism — it tells you exactly what to go back to in First Aid.
You'll have roughly 10–11 bookmarks per 20-question block. That's the expected number. Don't be alarmed — these bookmarks are the map for your review session. After your second block (so 40 questions, ~20 bookmarks), that's when you review. Go to First Aid and work through every bookmark.
The Review Method
Once you have 20–40 bookmarks (after 1–2 blocks), open First Aid and go through each one systematically. This is where the real learning happens — not during the question itself.
60–70% of UWorld questions are direct lines from First Aid. Your job in the review session is to find those lines and highlight them.
Read through the question and explanation again. Identify the key concept that you missed or got wrong on the first pass.
Most concepts have a direct equivalent in First Aid. Locate the relevant page — use the index at the back of the book if needed. Find the specific line that, if you'd remembered it, would have answered this question correctly.
That's it. Highlight the line. Do not write paragraphs in the margins. Do not add pages of annotations. Just highlight the line you missed. That highlight is a flag — it means "this is what UWorld tested that I didn't know."
Some UWorld concepts are UWorld-only and don't appear directly in FA. Find the closest related section in First Aid using the index. Write a single short one-liner near that concept — not a full note, just enough to capture "this can be tested this way." This is the exception, not the rule.
If a concept from one system shows up in another — e.g., a renal question that connects to biochemistry — find both pages in First Aid and write a small note on each: "see page X" or "connects to renal." These connections are how Step 1 is actually tested. Building them manually is more powerful than any flashcard.
First Aid is already comprehensive. If a concept is being tested in UWorld, the line is already in First Aid — you just didn't notice it. Don't add extra content to the book. That wastes time and dilutes what's actually important. Highlight. One-liner maximum. Nothing else.
Non-Negotiables
The 2-day First Aid + Vault phase is non-optional. If you skip it, you're learning from scratch in UWorld. That's the hardest way to do it.
Timed mode is for the NBME phase only. During system-based study, untimed tutor mode is the setting — always.
20 questions is the block size for the actual exam. Get used to it now. Don't run 40-question blocks during system study.
Re-doing UWorld questions teaches memory, not understanding. Always review bookmarks by finding the concept in First Aid and highlighting it. That's the review method. Don't redo.
Low UWorld scores early in a system are expected and correct. The first system often starts at 40–50%. That's not failure — that's the tool showing you what to go back to. Don't let early scores affect momentum.
After completing most of a system's questions, if your last two blocks are still under 60%, the concept layer hasn't clicked yet. Go back to the Mehlman videos for the topics you keep missing, then the First Aid pages behind them, before moving on. Don't just push through with weak foundations.
