Everything you actually need for Step 1 fits in five — because one of them absorbs the rest. Kaplan, Boards & Beyond and Bootcamp are not on the list, and that is deliberate.
For years the advice has been to add. Kaplan, Boards & Beyond, Bootcamp, another qbank, another video library. That advice is out of date and it is expensive in the only currency that matters.
The filter I use is one line: if it does not move your UWorld score, it is not a Step 1 resource. Five things survive that test. Everything that failed it is in a separate list.
This is the resource that lets the list be five instead of forty, because everything people normally buy separately already lives inside it, anchored to the same page numbers.
What it is: the spine. Everything else on this page either explains it, tests it or repairs it.
How: page by page, system by system, with every extra point you learn written into the page — never into a second set of notes. One book at the end, revised once. Four readings, each doing a different job, and the whole thing is done in about eight weeks.

What it is: a learning and assessment tool, not a first-pass resource. Opened cold it returns 40% and convinces you the problem is you. It is not; it is the order.
How: Read the system in First Aid → Pre-solve with that page’s MCQs → Solve by system in tutor mode, 20 questions → Review every miss back into the First Aid page it came from. That review is your second and third pass of the book.
Leave a system when your last two blocks hold above 65% — a score, not a date.
→ The RPSR method · when a system is actually finished
What it is: the one thing that tells you whether you are ready. You get eight forms — never burn one on a cold baseline.
How: always offline. 10 blocks of 20 questions, 30 minutes each, first pass finished by 23. Pair a form with a Free 120 and you have 14 blocks — a real exam day.
Ready means above 67–68% on NBME 31, 32 and 33, consecutively and progressively.

What they are: the only two video resources that earn their hours. Both free, both dense, and neither one is a first pass.
Mehlman teaches how the examiner thinks rather than the answer. Conditional: the moment a system’s UWorld drops under 65%, sort his playlist by date and watch the last three years. Above 65%, skip him. His HY Arrows document is different — keep it open throughout, and run it hard when an NBME stops moving.
Neil Randy is the most slept-on channel there is, and not just for biostats — cardiovascular, CNS, psychiatry, ethics, biochemistry. Run him before an NBME and again before the exam. Worth 5–10% on its own.
