Why UWorld is not enough for your NBME score

For IMGs who finished UWorld and watched the NBME stay put.

By Dr. Marish Asudani · Published

Why is UWorld not enough for my NBME score?

Because UWorld is a resource that helps you understand and apply First Aid. It isn't First Aid. You still need to understand First Aid (the First Aid Guide), apply it (Mehlman) and recall it (FA Foundation Anki). And once UWorld is complete, you revise the entire First Aid from everything UWorld taught you.

Read this first"I finished UWorld. Why is my NBME still stuck?"

I hear this every week. The student did every block. Some did UWorld twice. And the NBME sits in the same place.

Their problem isn't how many blocks they did. This page is 3 jobs, 3 tools, and 2 necessities. That's it.

1

What it isWhat UWorld actually is

UWorld is a learning and assessment tool. It is not your first-pass resource, and it's not the source of the exam. 60–70% of UWorld questions are direct lines from First Aid. UWorld takes those lines and puts them inside a patient.

That makes UWorld brilliant at 2 things: it shows you whether you understood a First Aid line, and it trains you to apply it. What it can't do is make you remember the 646 pages that the NBME is drawn from. That's still on you.

The 3 jobsUnderstand First Aid, apply it, recall it

⭐ THE WHOLE IDEA

Every point on your NBME comes from 3 jobs done on the same book. Each job has its own tool.

JobToolWhat it does
UnderstandThe First Aid Guide (what it is)Every page decoded: Focus On, ELI5, How is this tested?, and MCQs on that exact page
ApplyMehlman's videosHow the exam asks each page: which clue rules an answer in, and which rules it out
RecallFA Foundation Anki (how to run it)Every high-yield line of First Aid asked back to you, with the page number on every card

The First Aid Guide helps you understand First Aid. Mehlman helps you apply it. Anki helps you recall it. UWorld sits on top of all 3 and tests them.

During UWorldNecessity 1: understand First Aid using UWorld

The first necessity is to use UWorld to understand First Aid. Not to collect a percentage. Every question you get wrong, and every one you got right by guessing, goes back to the exact First Aid line it came from.

  1. Bookmark every wrong answer and every lucky guess.
  2. After every 2 blocks, find the First Aid line behind each bookmark and highlight it.
  3. Read a couple of lines above and below. 5–6 minutes a question at most.

Do that and every UWorld block becomes another reading of First Aid. Skip it and UWorld is just a score you forget.

After UWorld is completeNecessity 2: revise the entire First Aid from all of UWorld

⭐ MOST SKIPPED

When you've completed UWorld, you're not done. Now you have to revise, recall and bind all the information you have, and consolidate it. Everything UWorld taught you is waiting in highlighted lines across the whole book. This is when you bring the whole book back.

You can't reread 646 pages in a week. You can recall all of them in 6 days:

What it looks like2 students, same UWorld

UWorld only

  1. Finishes UWorld, reads the explanations.
  2. Starts a second pass of UWorld.
  3. Gives the NBME. Remembers the questions, not the pages.
  4. Stuck.

UWorld + First Aid

  1. Every miss traced to its First Aid line.
  2. UWorld complete → whole First Aid revised in 6 days.
  3. Gives the NBME with the book in their head.
  4. The score measures knowledge.
The short version: understand with the First Aid Guide, apply with Mehlman, recall with FA Foundation Anki. Use UWorld to understand First Aid, and once UWorld is done, revise the whole of First Aid from everything it taught you.
