DAT Booster vs. Chad's Prep for Chemistry: Which Wins?

Short answer: DAT Booster is built around dense, exam-style chemistry questions with brief explanations, while Chad's Prep is built around long-form video lessons that teach general and organic chemistry from the ground up. If you already know the material and want reps, Booster's style fits. If you need someone to teach you the concept first, Chad's Prep's style fits. Most students end up leaning on one of the two, then adding full-length practice tests to actually build DAT chemistry pacing, which neither one is designed to do.

We're the founders of DATPractice, and we've been asked this question enough times to write down our honest reasoning. Obvious disclosure: we built DATPractice, so read this knowing where we stand. We'll still describe both companies fairly.

How DAT Booster and Chad's Prep Approach Chemistry Differently

General chemistry and organic chemistry together make up 60 of the 100 questions on the Survey of Natural Sciences section (30 general chemistry, 30 organic chemistry, plus 40 biology). That's more than half the science section, so how you learn it matters a lot.

Both DAT Booster and Chad's Prep are popular, well-established resources that plenty of high scorers have used. They just start from opposite ends of the same problem:

• Chad's Prep is generally known for a teaching-first approach: long-form video walkthroughs that build up chemistry concepts the way a patient professor would, often used by students who need a first real pass through the material or who are shoring up weak fundamentals.
• DAT Booster is generally known for leaning harder into practice: a large volume of exam-style chemistry questions meant to get you pattern-matching against DAT-style wording once you already have the concepts down.

Neither description is a knock on the other. They're different tools built for different stages of the same climb.

DAT Booster's Chemistry Style: What You're Actually Getting

Booster's chemistry content is typically associated with shorter, punchier explanations attached to a large set of practice questions, aimed at students who want to drill. That structure suits people re-learning material they took in undergrad, or students who've already been through a textbook or another course once and now just need volume.

The tradeoff: if a concept genuinely never clicked for you, a shorter explanation attached to a practice question isn't always enough to fix that. You may need to pair it with something that teaches it more slowly first.

For exact course structure, current question counts, and pricing, check DAT Booster's own site directly, since course content updates over time and we don't want to state anything about it as fact that might be outdated.

Chad's Prep's Chemistry Style: What You're Actually Getting

Chad's Prep chemistry content is generally associated with longer video lessons that walk through a topic methodically, which is exactly what a student rebuilding general chemistry or organic chemistry from a shaky foundation usually needs. If you're the kind of student who needs to see why a mechanism works, not just memorize the arrow pushing, this style tends to land well.

The tradeoff here: thorough, ground-up teaching takes time, and time is the one resource every DAT student is short on. If you already have a decent chemistry base, working through every lesson start to finish can eat weeks you don't have.

Again, for current video counts, topics covered, and pricing, Chad's Prep's own site is the accurate source, not a third-party comparison article.

DAT Booster vs Chad's Prep Chemistry: Which One Should You Pick

Here's how we'd actually decide, based on where a student is starting from:

1. Never took organic chemistry seriously, or it's been years: lean Chad's Prep first. You need the teaching before you need the reps.
2. Solid chemistry background, just need DAT-style reps: lean DAT Booster. You don't need re-teaching, you need volume and exposure to how the DAT phrases things.
3. Mid-prep and stuck on a specific weak topic (e.g., equilibrium, resonance, SN1/SN2): use whichever one has the stronger single lesson on that exact topic, and don't feel obligated to buy the whole course to fix one gap. A focused reaction summary can also close small gaps fast — our DAT Ochem cheat sheet is built for exactly that.

What we wouldn't do is buy both in full expecting double the benefit. The general chemistry overlap between any two mainstream chemistry resources is large, and your prep time is worth more spent elsewhere, like memorizing high-yield reactions or running full-length practice.

The Gap Neither One Fills: Full-Length Chemistry Section Pacing

This is the part that actually costs students points on test day. Learning 30 general chemistry questions' worth of concepts one topic at a time, whether through Booster's questions or Chad's Prep's videos, is not the same skill as answering 30 general chemistry and 30 organic chemistry questions back-to-back inside a 90-minute Survey of Natural Sciences section, mixed in with 40 biology questions, under real time pressure.

Neither DAT Booster nor Chad's Prep is primarily built to simulate that. That's a pacing and endurance problem, and it only gets solved by running full, timed, exam-format science sections repeatedly until the rhythm is automatic.

That's the specific gap we built DATPractice to close.

Our Honest Take on DAT Booster vs. Chad's Prep for Chemistry

We scored in the top 3% on the DAT (legacy-scale 25 AA with a 30 in organic chemistry, and 27 AA with a 29 Total Science) and we're now at the #1 dental school in the world. We didn't get there by using every resource on the market. We got there by using the fewest resources that actually taught the concept and built exam reps, then stopping.

If we were starting chemistry from scratch, we'd lean toward the teach-first approach that Chad's Prep is known for. If we already had a chemistry foundation and just needed exam-style reps, we'd lean toward the drill-first approach Booster is known for. Either way, we'd pair it with full-length, timed practice tests early, not two weeks before the exam, because pacing under real conditions is its own skill that no amount of untimed video-watching or isolated question sets builds on its own.

DATPractice exists because we didn't want to pay for five different products to cover five different jobs. Our 40 full-length tests, 11,000-plus question bank with written solutions, and AI tutor are built so chemistry content, chemistry drilling, and chemistry pacing all live in one place. Whatever you choose for the concept-learning stage, that's the layer we'd add next.

For students specifically shoring up organic chemistry reactions, our high-yield ochem reactions guide is a fast way to see what's actually tested before you commit hours to any single course.
