Stuck at 62–65% on your NBMEs for weeks?
These next three moves are what pushes my students above 70%. The third one is the most important — don't skip it.
A plateau isn't a talent problem, it's a strategy problem. You've already studied these systems once. The fix isn't more of the same — it's hitting the same material from a sharper angle and front-loading what the NBME actually tests. Here's the exact 3-step method. 👇
1
Close your knowledge gaps from a new angle
If you keep missing questions from one particular system, that's a knowledge gap — not bad luck. Fix it in two moves:
- Watch the Mehlman Medical videos for that system.
- Then do the AMBOSS high-yield concepts (Step 1) for that same system.
Why it works: you've already learned this system from First Aid once. Coming at it through Mehlman + AMBOSS gives you a fresh angle on the same content, which is exactly what fills the gaps First Aid alone left behind.
2
Run the two high-yield PDFs
Two PDFs do an enormous amount of work in the final stretch:
- The Randy Neil High-Yield PDF
- The Mehlman High-Yield Arrows PDF
Both are linked for you in the University → Files section.
Why it works: these two PDFs alone have helped several of my students gain at least 10 points on their next NBME — they distill the highest-yield concepts into exactly what shows up on test day.

The NBME Booster deck
⭐ MOST IMPORTANTThis is the one that breaks the ceiling. The NBME Booster deck on the Vault pulls high-yield, system-by-system points straight from NBME 20 through NBME 33. Before your next NBME, do the cards system by system — and you'll cover every high-yield point the NBME has tested over the past five years.
Example: You took NBME 28 last week and you're taking NBME 29 next week. Go to the
NBME Booster deck, and cover
NBME 20 through 28, all systems. That's every important point the test has already asked — front-loaded right before you sit the next form.
Why it works: the NBME recycles itself. The topics on form 30 were already tested on forms 20–25. Drilling them by active recall means you walk into your next form already knowing the patterns it uses to test you.
What this does: students stuck in the low 60s have moved past 70% in a single form using these three moves — and the same active-recall work pulls UWorld up alongside it.
