6 playlists = 6% growth (Step 1 edition)

For IMGs who would rather watch than scroll tonight. All free, all Step 1.

Which YouTube playlists should I watch for USMLE Step 1?

My 6: Neil Randy's psychiatry playlist, Neil Randy's biochemistry, Dirty Medicine's ethics, and Mehlman's heme-onc, immunology, and microbiology with pharmacology. Everyone watches Neil Randy for biostats, but his psychiatry playlist is what brings the real difference. Run Neil Randy as revision, in the weeks before your NBME, with First Aid open. Watch Mehlman's videos, not his PDFs.

Read this firstThe pattern with YouTube for Step 1: the good stuff is free, it's already out there, and almost nobody uses the right part of it. Students watch the famous playlist and skip the one that would have moved their score.

So here are the 6 playlists I'd give you, with what each one is for and when it comes in. Then the full 10, for when you've done these.

Short on time tonight?Start with 1 video, not a playlist

If a whole playlist is too much for tonight, start with my 90-minute antimicrobials video. It wraps up all of the antimicrobials in 90 minutes. Watch it once at the start of your prep and again 1 week before your exam. How to use it →

The playlist nobody watches

Do it once, goated forever

  • What: the ethics playlist.

Every topicThe best video is already on the page. Here's how we do it.

Playlists are for whole systems. For a single topic, you don't need to search at all.

  1. We went through First Aid page by page. My team and students who had just passed picked the best video on YouTube for the topic, on every page that needs one. Sometimes Dirty Medicine, sometimes Neil Randy, sometimes Mehlman.
  2. It sits on the page itself. Open a page of the First Aid Guide and the video is there, next to what the page tests and how it's tested.
  3. The MCQs are right under it. Watch, then test that exact page in the same minute. No rabbit hole, no 3 hours of searching.

Try it on Renal, freeFirst Aid Guide · Renal: the videos, what each page tests and the MCQs, page by page.
