The Last Month Before Step 1: The Exact Day-by-Day Plan

Your content is done and NBME 27 is behind you. This is every day from there to the exam: consolidation, and no new content. It is the plan Part 6 of the video points to.

The whole month in 1 line.

Only NBME 31, 32 and 33 carry the verdict. Everything else this month is consolidation: the NBME Booster system by system, Randy Neil, Mehlman High-Yield Arrows, full 14-block days, then a final week with nothing new.

68%+

On all 3 of NBME 31, 32 and 33. Not your best of 3.

3–4 min

Left on the clock at the end of your blocks.

40 a day

Mehlman High-Yield Arrows. All 160 in 4 days.

Am I ready? The 33 days The final week Not at 68%?

First: how you know you are ready

Only 3 forms carry the verdict: NBME 31, 32 and 33. Everything before them is training. Even NBME 34 is not that predictive.

The trend beats a single number. Scoring around 68–73% and 1 form drops to 65%? That does not undo the rest of the evidence. It was 1 bad day, not a collapse.

A single spike is noise. Stuck at 63, 64, 65% and 1 form jumps to 71%? That is not a reason to take the exam. That 1 form could be the anomaly, and you would be taking the exam too early.

The bar, both halves of it: you are above 68% on all 3 of NBME 31, 32 and 33, and you are finishing your blocks with at least 3–4 minutes left. Both conditions, or you are not ready. The full reasoning is in How to Know You're Actually Ready.

Day by day

The 33 days, from NBME 27 to the exam

In the Vault schedule, the stretch after your first NBME is normally 33 days, and your exam date is 35 days after your first NBME. This is that stretch, in order. The form order is the one from Part 5: 28, 29, the NBME Booster, then 31, 32 and 33, and the Free 120.

Day	What you do
Days 1–10	Repair round. 1 system a day: that system in First Aid in the Vault, or its Foundation Anki deck. Fix exactly what NBME 27 exposed. NBME 28 and 29 go in as timed 20-question blocks, offline, reviewed the same day.
Days 11–17	NBME Booster, forms 20–30, system by system. Finish every system before your next form. The last 3 of these days also carry 2 blocks of NBME 31 each.
Day 18	Full-length day 1: NBME 32 plus the last 4 blocks of NBME 31. 280 questions, 14 blocks of 20. Same wake time, same breaks as the real exam.
Days 19–22	Randy Neil PDF + Mehlman High-Yield Arrows. Arrows 1–40, 41–80, 81–120, 121–160: 40 a day, all 160 in 4 days. The Randy Neil PDF takes 2–3 days at most. Clear your due Anki and revisit what full-length day 1 exposed. Days 21 and 22 also carry 1 block of NBME 33 each.
Day 23	Full-length day 2: the rest of NBME 33 plus the Free 120. 280 questions, a full 14-block day.
Day 24	Review day, and the verdict. Review the Free 120 and NBME 33 in full, every question, with the review protocol. You now have NBME 31, 32 and 33. Check them against the bar.
Days 25–26	NBME Booster, forms 31–33, system by system. Half the systems on day 25, the other half on day 26.
Day 27	Full-length day 3: Vault Assessment 1. 14 blocks, 280 questions, under exam conditions.
Days 28–32	The final week. Nothing new. See the breakdown below.
Day 33	The day before. Rapid Review and weak systems from First Aid until 5–6 p.m., books closed, lights out at 9 p.m. The full day-before plan.
Exam day	14 blocks of 20. 3 deep breaths after every 20 questions, a 5–7 minute glucose break after every 40.

Why this order: the forms you have already taken become flashcards before the forms that count. You walk into NBME 31, 32 and 33 having already harvested 20 to 30. Then the forms that carry the verdict are taken as full exam days, not loose blocks, because a 14-block day is the only thing that trains the stamina.

The 7 NBME Booster days, system by system

Run it system by system, never form by form. This is how the systems split across days 11–17:

Day	Systems	Plus
Day 11	Renal · Respiratory · General Pharmacology	—
Day 12	GI & Liver · Biochemistry	—
Day 13	Reproductive · Endocrine · General Pathology	—
Day 14	Immunology · Heme / Onc · Ethics	—
Day 15	MSK · Microbiology	NBME 31, blocks 1–2
Day 16	Psychiatry · CNS	NBME 31, blocks 3–4
Day 17	Cardiovascular · Pharmacology · Biostatistics	NBME 31, blocks 5–6

Short on time on a given day? The counts are a recommendation, not a quota. Take the systems you are weakest in first. How the Booster is built, and why it works: The NBME Booster.

Days 28–32

The final week: nothing new

In the final week you don't do anything new. This is all you do:

Daily

First Aid Rapid Review, plus the FA Foundation Anki or the NBME Booster Anki. Then the Mehlman High-Yield Arrows and the Randy Neil PDF again. You have seen them once, so this pass is fast.

Spread across the 5 days, alongside the daily work:

Day	Add this
Days 28–29	Pharmacology revision straight from First Aid, then the NBME Booster, pharmacology only: every pharmacology question from the NBMEs, as flashcards.
Days 30–31	Sketchy for micro, and the 90-minute high-yield antimicrobials video. Then the NBME Images Anki: every image asked in the NBMEs, as flashcards.
Day 32	The High-Yield Biostats PDF, then finish whatever is left of the Images deck and the pharmacology deck.

Why only revision: you don't learn in the last stretch. You consolidate and you actively recall. Every item above is something you have already studied, now asked back to you. The full list of last-fortnight resources, with links to the PDFs: The Last 2 Weeks.

Not above 68% on 31, 32 and 33?

Then don't make this your final month. You only take the exam if you are above 68% on NBME 31, 32 and 33. If you are stuck in the 60s, another month of the same plan will not move it.

Fix the plateau first. Stuck at 62–65% on your NBMEs has what to study to get over it and into the 68%+ range.
