The Seven Sheets

Everything from the post, in one place. Every download is free — and every one carries the rule for when it enters your prep, which is the part that actually matters.

You were never missing a resource. You were missing the rule that says when each one is allowed in.

A list without a WHEN attached to every item is not a plan, it is a shopping cart. That is why you can own eleven resources and still not know what tomorrow morning looks like. So each sheet below has its trigger written on it.

👉 All seven are sequenced for you day by day on usmlevault.com — FREE for your first 3 days →
1
Sketchy Micro — the 6-day week
85 bugs · 6 days · same-day testing

The order matters more than the hours. Days 1–3: DNA viruses, then RNA viruses, then parasites. Days 4–6: fungi, gram positives, then gram negatives, atypicals and spirochetes. About 20 hours of video total.

The method is watch-then-test, same day. Watch once with no notes, recall the whole story out loud, watch again at 1.75× for the gaps only, read the PDF, then do that day's MCQs before you sleep. Skip in Sketchy and read from First Aid instead: TB, COVID, HIV, Bunyaviruses and malaria.

When: your foundation week, before you touch a single system. Once, properly — and never again as a block. The goal is completion, not mastery.
2
The High-Yield Pharmacology PDF
Free download · your pharm syllabus

The reason pharm takes people three weeks is not difficulty — it is disorganisation. Nobody tells you which drugs are high-yield, and nobody tells you which resource teaches each one best. So you watch everything, from everywhere, twice.

This PDF is the answer to both questions in one document: every high-yield drug stratified by system, and the exact resource to learn it from. Keep it open the entire time — it is your syllabus, your reading material, and your checklist.

When: your foundation week alongside micro, then again as the reference every time you reach a new system's pharmacology.
3
The First Aid Guide
646 pages · 2,534 page-by-page MCQs

First Aid was written to remind, not to teach — which is why reading it cold does not work. The Guide decodes the book page by page. Every page carries Focus On, a Concept Walkthrough, "How is this tested?", Key Takeaways, and Test Yourself MCQs on that exact page.

The "How is this tested?" block is the one people screenshot: Common Confusion → Core Concept → The Trap → Your Approach. Written by people who scored 80%+ on their NBMEs, including me. Alongside it, ~2,002 ELI5 explanations, ~870 mnemonics and pearls, and 367 First Aid 2026 change cards.

When: every single day of the systems phase — this is the first of your four passes through First Aid. The Renal system is free, so you can test the loop before anything else.
4
The Neil Randy PDF
Free download · his whole library, mapped

Everyone thinks Neil Randy is only good for biostats, and almost nobody works through his full channel — which is exactly why it is an edge. This PDF breaks his entire video library down system by system, so you can run the videos that matter without hunting.

It is not just biostats: cardiovascular, CNS, psychiatry, ethics, biochemistry. Running it moved my scores, and my students', by 5–10%.

When: right before an NBME, and again in the run-up to your exam. It is a revision instrument, not a learning one.
5
Mehlman's High-Yield Arrows
Free download · one dense multi-system document

Not a playlist and not a per-system resource — a single dense document covering every system at once, built around the up-arrow / down-arrow relationships the exam keeps asking about.

Keep it open the whole way through your prep, and run it hard the week an NBME stops moving. It is the highest-yield thing available in a plateau.

When: throughout, and specifically to break an NBME plateau. Note this is not conditional on a UWorld percentage — that rule belongs to Mehlman's videos, which are a different resource with a different job.
6
Foundation Anki
~2,400 cards · the whole of First Aid

A page-by-page aggregation of First Aid — the actual high-yield lines of every page, asked actively, with the page number printed on every card so you can jump straight back to the book when one makes you hesitate.

Around 2,400 cards, not 30,000. At ~400 a day that is a complete First Aid pass in five to six days, which is a sentence worth re-reading.

When: two ways. During a system, straight after Mehlman, to lock it in over about two days. Then cumulatively in your consolidation window before every NBME.
7
NBME Booster
4,174 cards · forms 20–33

Everything worth keeping from fourteen retired NBME forms, turned into active recall. This is the deck for when you need points rather than content — you already know the material, and what is missing is the specific way these forms ask it.

When: the final one to two weeks, and before you move on to the newer forms. Not before. Run it early and you are testing yourself on material you have not built yet.

The whole sequence, on one line each

This is the part the resource lists leave out. Same seven sheets, ordered by when they enter:

PhaseWhat comes in
FoundationSketchy Micro, then the High-Yield Pharmacology PDF. Once, start to finish.
Every systemThe First Aid Guide daily · Mehlman's Arrows open throughout · Foundation Anki after each system
Before an NBMEThe Neil Randy PDF · a full Foundation Anki cycle
PlateauMehlman's Arrows, run hard
Final 1–2 weeksNBME Booster · Neil Randy again · no new content
That table is the actual product. Every sheet above is free or nearly free — the sequencing is the expensive part, and it is what people are really missing when they say they have "tried everything."
And you do not have to hold the sequence in your head. On usmlevault.com you answer four questions and the same rules become a day-by-day plan built backwards from your exam date — micro and pharm placed at the front, biochem split into the systems that need it, Anki placed after each system, and the NBME window at the end. Free for your first three days.
The guides behind each sheet.
The Resource Stack — the same treatment for Step 2 CK and Step 3.
How to actually complete First Aid — four readings, eight weeks.
The four resources I would never use again — what to delete to make room.
Seven sheets is not a plan.
A dated schedule with each one placed where it belongs is. Four questions, and it builds itself.
