The best free DAT practice comes from the ADA itself: free practice questions on its DAT site, plus a full official practice test that's free with a partial fee waiver and $100 otherwise. Prep companies add free practice tests and free accounts you can try before buying a course. This guide lists every DAT practice test option we could verify for 2026, what each includes, when the official test is worth paying for, and how to use practice tests so your scores mean something. It's for pre-dental students planning their DAT prep on a budget, and it matters because practice tests are where most of your score gains come from. Facts were checked on November 7, 2026.

Official

The Official ADA DAT Practice Test

The ADA sells a full DAT practice test for $100, or single modules for $20. It's written by the test makers, but it reports only how many questions you got right, not a scaled score.

ModuleItems
Biology 10140
General Chemistry 10130
Organic Chemistry 10130
Perceptual Ability 10130
Reading Comprehension 10125
Quantitative Reasoning 10140

The full test takes 3 hours 5 minutes, and you have 24 hours to complete each purchase. Perceptual Ability 102 and 103 are sold only as single modules. If you qualify for the ADA's partial fee waiver, one full DAT practice test is included free. Source: the ADA's DAT application page and the 2026 DAT Candidate Guide.

Because the modules are shorter than the real DAT (the real PAT has 90 questions, not 30) and give no scaled score, use the official test for question style, not to predict your 200–600 score. Our DAT scoring guide explains the real scale.

Free options

Free DAT Practice From Prep Companies

The Princeton Review offers a free DAT practice test, DAT Bootcamp has a free account, and Booster Prep has a free PATBooster version for the Perceptual Ability section.

  • The Princeton Review: a free DAT practice test.
  • DAT Bootcamp: a free account ("Start studying for free"); the site doesn't say what's included, so check at signup. Read our DAT Bootcamp review.
  • Booster Prep: DATBooster has no free version, but PATBooster's free version includes 1 practice test and 90 Perceptual Ability questions. Read our DAT Booster review.

Company practice tests use each company's own score scale, so scores from one aren't comparable with another. See how accurate DAT Booster and DAT Bootcamp practice tests are.

Verdict

Is the $100 Official Practice Test Worth It?

Yes, for most students, as a final check. It's the closest you can get to real DAT questions, and $100 is a fraction of the $580 exam fee. Skip it if your budget is tight and you already use a full prep course with 10 full-length tests.

Strategy

How to Use DAT Practice Tests

  1. Take a free diagnostic first to find your weak sections.
  2. Drill weak areas with your course's question bank rather than using up full tests.
  3. Take timed full-lengths every week or two in your final six weeks.
  4. Save the ADA practice test for your last 7–10 days.
  5. Track trends, not single scores. Our 3-month DAT study schedule shows where each test fits, and our PAT score guide covers Perceptual Ability practice.

FAQ

Is there a free official DAT practice test?

The ADA posts free practice questions on its DAT site. Its full practice test costs $100, or $20 per module, but one full test is free if you qualify for the ADA's partial fee waiver. The Princeton Review also offers a free DAT practice test.

Does the ADA practice test give a DAT score?

No. The ADA reports only the number of questions you answered correctly in each module, not a scaled score. Use it to check question style and readiness in your final week, rather than to predict your score on the real 200–600 scale.

How many DAT practice tests should I take?

Most students take six to ten full-length tests over a three-month plan, mostly in the final six weeks. DAT Booster and DAT Bootcamp each include 10 full-length tests, and the ADA practice test works best as a final check in your last 7–10 days.
