Best DAT YouTube Channels for Free DAT Prep in 2026

The best DAT YouTube channels for biology and chemistry review are general science channels, not DAT-specific ones: Crash Course, Khan Academy, Professor Dave Explains, Leah4Sci, and AK Lectures all cover the content the science section actually tests, for free. For PAT, the honest answer is that YouTube is thin, because PAT is a visual skill built through repetition, not a lecture-driven one. Either way, watching is step one, not the whole plan: the score comes from what you do after you close the video.

We've both scored in the 97th-plus percentile on the DAT and now build practice tools for a living. Here's the ranking, section by section, and the case for why passive video has a ceiling that only active, timed practice breaks through.
