✅ How I finished Step 1 in 14 weeks
The real problem
❌ Problem 1

You can't find the right video for the topic you're stuck on.

&
❌ Problem 2

You start one video and fall into a 3-hour rabbit hole — learning nothing.

The problem was never the videos. It's knowing which to watch, and where they fit.
The secret that ties it together

We mapped the best video to every First Aid topic

First Aid — page by page, topic by topic→ The single best YouTube video for each→ Linked for you — no searching

The Antimicrobials Video

90 min
All of antimicrobials, one video. A topic that feels endless — made finite. And free.
▶ Watch — all antimicrobials in 90 minutes
usmlevault.com. This is where I've aggregated all of those important YouTube videos, page by page, topic by topic. So let's say biochemistry terrifies you. You open any single biochemistry page, and right there on the page is a two-to-three-minute YouTube video that me and the students who just passed actually watched to understand that exact topic. Sometimes it's Dirty Medicine, sometimes Neil Randy, sometimes Mehlman — whatever we found to be the single best video on all of YouTube for that topic, it's linked right there. You never have to go searching YouTube again.">
