NBMEs offline: the complete system

For IMGs about to open an NBME, Step 1 or Step 2 CK. Read this before you buy, book or start your next form.

By Dr. Marish Asudani · Published

Should I take NBME practice exams online or offline?

Offline, always. The online version gives you 50 questions in 75 minutes. It feels spacious, and it inflates your score by 4 to 6%. Offline, you give 10 blocks of 20 questions, 30 minutes each, which is the pace of the real exam. Take your first form only after every system is finished and a dedicated week, follow the order from NBME 26 to 33, and review every form the same day. For Step 1, only the trend on NBME 31, 32 and 33 predicts.

Read this if you want to pass Step 199% of IMGs won't do this. They buy an NBME, open it online, get a number, and book their exam on it.

My students do the opposite. It is not 1 decision, it's 7, and each one has its own guide.

So this page puts all of them in one place. Each card is short. The full detail lives in the guide each card links to. Tap a card to open it.

Why it matters

NBMEs are the most high-yield resource we have as IMGs. They are the only thing that honestly assesses how ready you are. And there are only so many of them.

For Step 1 you get 8 to 9 forms. Every form you burn early, online, or before your content is done is a form you can't use later, when the number actually means something. Never burn an NBME on a baseline.

The rule this whole page follows: every form gets the right format, at the right time, and a same-day review. Skip any 1 of the 3 and the form tells you less than it should.

Why offline

Online NBMEs give you 50 questions in 75 minutes. That's spacious, and in my experience it inflates your score by 4 to 6%. You book your date on a number that was never real, and you train a pace you'll never use.

30 minutes, longer stems

30 minutes for 20 questions is 90 seconds a question. Offline trains exactly that. And the real exam has longer stems than any NBME, so if you can't move decisively at pace on an NBME, the stem length alone will cost you on exam day.

How to give it offline

Every form, 26 through 33, is 200 questions. Offline that is 10 blocks of 20, 30 minutes each, hard stop. That unit never changes.

  1. Start in the morning, like the real exam. Begin at 7:30 or 7:45. No phone for the 30 minutes before you start.
  2. Mark your answers on a sheet of paper, A to E, block by block. You need that sheet for the score check in the review.
  3. Run 3 timers. 30 minutes per block (resets every block, hard stop), your total break time, and the overall clock: 5 hours of questions plus your breaks.
  4. 2 passes in every block. First pass in 23 to 24 minutes, never more than 1 minute 20 seconds on a question. Torn between 2? Write B / C on paper, flag it, pick one, move. Spend the last 6 to 7 minutes only on your flags.
  5. Breaks. After every block: 3 deep breaths, then the next 20. After every 2 blocks: a 5 to 6 minute break. Restroom, water, glucose. Keep the total to roughly 40 to 45 minutes across all 10 blocks.
  6. Simulate completely. No phone, no breaks outside the structure, no pausing mid-block.
Why only 40 to 45 minutes of breaks? That's right for a 10-block NBME. The rest of the break time is still there on exam day, because the real exam is 14 blocks, not 10.

How to give your first one

If your first NBME goes badly before you're ready, it can destroy your confidence for weeks. So the first one has 2 conditions.

  1. Every system finished first. Not "read". Finished: every UWorld question in the system, last 2 blocks above 65%. Never in week 3. When a system is actually finished →
  2. A dedicated week before it. 7 days at 10 hours a day: 1 hour of Sketchy Micro every morning, organism by organism; FA Foundation Anki in the order you studied the systems, First Aid open beside you; and 2 timed offline blocks of 20 from NBME 26 every day.

FA Foundation Anki for the dedicated weekAll 17 systems in First Aid order. Every card maps to its First Aid page, so you can keep the book open beside you.

Day 8 is NBME 27, 200 questions, exam conditions. NBME 26 stays in blocks during the week so your scored forms are preserved.

▶Before giving your first NBME, watch thisThe dedicated week and the 2-pass block method, from me.

On your Vault schedule, both of my NBME videos are already tasks before your first form: how to give your first NBME, and how to solve NBME blocks. The whole dedicated week is laid out day by day.

The order

Step 1 forms run 26 through 33, in 4 groups. Each group has something you finish before you open it, and each one hands you the syllabus for the next.

The 3 that predict

Ready means 68% or more on all 3 of NBME 31, 32 and 33, climbing, not wobbling. 67, 70, 73 is ready. 68, 67, 68 is a plateau. Only the trend predicts. 1 good form out of 3 is noise.

On the schedule, 32 and 33 are full 14-block days, the shape of the real exam. NBME 31 runs as 6 blocks during the NBME Booster Anki days, and its other 4 blocks join NBME 32 as Mock Exam 1. NBME 33 and the Free 120 make Mock Exam 2. On Step 1, the Free 120 is practice for the full day, not a predictor.

The predictive ones are NBME 13, 15 and 16 as a trend, and the Free 120 is the most predictive test on Step 2 CK (only on Step 2): 80% or more on it = a good chance of 250+.

How to solve

Same 4 phases on every question, until it's automatic:

  1. The first 3 seconds. Labs, a derm image or a simple X-ray? Look at them first, then jump to the last line. Skip the ECG and complicated imaging.
  2. Read the stem with intent. Line 1 sets the scene. Build your diagnosis line by line.
  3. Decode the last line. Lock in diagnosis and management before you read it. "Next best step" and "gold standard" are different questions.
  4. Whisper your answer before you look at the options. Switch only if a line in the stem rules your answer out.

The single habit underneath all 4: never look at the options before the whole stem. Most "silly mistakes" come from breaking it.

How to review

The review is the exam. Taking the blocks is only half the work. Review the same day, 24 hours maximum, while you still remember why you picked the wrong option.

  1. Score check before answers. Find out which questions are wrong, block by block. Not why. Not the correct option.
  2. Cover the options. Read the stem only.
  3. Can you answer it now? Yes: practice gap, do a timed block on that topic. Blank: knowledge deficit, read the First Aid page and understand the mechanism.
  4. One-liner for every incorrect, filed by system, the same evening.

After it: the score, and the next form

On the Vault schedule, your first NBME picks 1 of 3 roads, and all 3 are planned before you give it. A low score is a known road, not a verdict.

Already took one online?

Don't throw it away. The review still applies: same day, score check first, stem only, one-liner per miss.

Just flag the score as an online score. It's 4 to 6% higher than it should be, so don't pick your exam date from it. Your next form goes offline.
