YouTube has become one of the best free resources for DAT preparation. Several channels offer high-quality content covering science review, PAT strategies, study tips, and dental school application advice — all completely free.
Whether you are supplementing a paid prep course or building a study plan entirely from free resources, these YouTube channels can fill critical gaps in your preparation without costing a dime.

| Gen Chem Content | ~3.5 hours | No | No | No |
| Biology Content | Multiple topic videos | No | 62 videos | No |
| PAT Content | No | 6-video playlist (all subsections) | No | No |
| Study Strategy | No | No | No | Yes |
| Application Advice | No | No | No | Yes |
| Subscribers | 8M+ | Growing | Growing | Growing |

The Organic Chemistry Tutor is the most popular free video resource for DAT science review. With over 8 million subscribers and dedicated DAT review videos, his channel offers more hours of quality science content than some paid courses.
The standout content includes a ~4 hour Organic Chemistry DAT review (90K+ views) and a ~3.5 hour General Chemistry review. Both are comprehensive, clearly explained, and directly relevant to DAT-tested material. His whiteboard-style teaching makes complex mechanisms and reactions easy to follow.
Best for: Students who need to build or refresh Gen Chem and OChem foundations.
Limitation: No PAT or Reading Comprehension coverage.

Mental Dental fills the single biggest gap in free DAT content: PAT preparation. Their 6-video PAT playlist covers keyholes, TFE, pattern folding, cube counting, hole punching, and angle ranking with clear strategy breakdowns.
The pattern folding video alone has 150K+ views, making it the most-watched free PAT tutorial online. Each video teaches specific strategies that you can immediately apply to practice problems.
Best for: Students who are intimidated by the PAT section or scoring below their target on PAT practice.
Limitation: PAT-focused only. No science content.

DAT Bootcamp's YouTube channel offers free playlists from one of the most trusted names in DAT prep. Their Biology playlist (62 videos) is the most comprehensive free Bio content available for DAT students, and their Organic Chemistry playlist (12 videos) covers core concepts.
The production quality is professional and polished, matching the standards of their paid platform. This makes the free content a good preview of what the full DAT Bootcamp experience offers.
Best for: Students who need thorough Biology review or want to preview DAT Bootcamp's teaching style.
Limitation: Only Biology and OChem are available. Gen Chem, PAT, and other sections are behind the paywall.

Predenting with Dr. Andrew takes a different approach from the other channels. Rather than teaching DAT content directly, Dr. Andrew provides study strategy advice, resource recommendations, and dental school application guidance.
This is the mentorship channel — it helps you figure out how to study rather than what to study. Videos on study schedules, resource comparisons, and application tips fill a gap that pure content channels do not address.
Best for: Students early in their predental journey who need direction and study planning advice.
Limitation: Does not teach subject content directly.
The best approach is to combine multiple channels based on your needs:
This combination covers science review, PAT strategies, and study guidance — all for free. The main gaps you will need to fill from other sources are timed practice tests and Reading Comprehension practice.
YouTube covers content review and strategy instruction well but cannot fully replace a structured prep program. You will still need timed practice tests, a question bank for active recall, and Reading Comprehension practice. However, YouTube content combined with free practice resources can get budget-conscious students a long way.
Start with Predenting with Dr. Andrew for study planning advice, then move to The Organic Chemistry Tutor for science review and Mental Dental for PAT strategies. DAT Bootcamp's YouTube channel is ideal for Biology-focused review.
The core science and PAT content on these channels covers fundamentals that do not change significantly from year to year. The strategies and concepts taught are applicable to the current DAT format.
