Crack DAT Reading - Transform Your DAT Score with Unlimited Practice Stop letting the Reading Comprehension section stand between you and dental school acceptance. Crack DAT Reading delivers UNLIMITED practice tests that have helped over 10,000 students achieve 400+ on the DAT score (20+ DAT scores on their old scale). The Game-Changing Difference Other apps offer a small, fixed question bank you'll finish in a week. Crack DAT Reading combines 10 full-length, test-day-authentic tests with an UNLIMITED test generator. Every generated test is entirely new - fresh passages and questions on any topic - so you never run out of material. Endless practice to build reading speed, accuracy, confidence, and scores.

Why You Can't Afford to Wait Most students underestimate Reading Comprehension because they assume they already know how to read. The DAT doesn't test casual reading - it tests speed, precision, and stamina across dense scientific passages under a brutal 60-minute clock. You can't cram those skills - you need time, exposure, and UNLIMITED repetition. Top scorers don't wing it or start late - they start early and practice consistently. The Real Cost of Being Underprepared One DAT attempt costs hundreds of dollars. An application cycle can cost thousands. If you're underprepared, the real cost isn't another testing fee - it can mean months of restudy, a retake, reapplying, and losing an entire year before dental school. That's why we built this app around unlimited generation instead of a small question bank. Keep practicing, keep seeing new passages, target weaker areas, and build the speed and pattern recognition that only repetition creates - without running out of material. Fear of Falling Behind? Your competition is looking for every edge. If someone walks in with far more Reading practice and faster comprehension under time pressure, that's a real advantage. While others get faster with unlimited practice, are you still planning to start "later"? Time runs out. The test doesn't wait. Don't let others take your dental school spot! A Straightforward Investment $50 for a month, or $200 for an entire year (about $16 per month for unlimited practice and a full-year head start). For a student facing years of tuition, expensive applications, and competitive admissions, about $16 per month for your DAT score is a straightforward decision. Everyone is free to prepare however they choose. We built this for students who would rather have every possible advantage than save a few dollars and wonder afterward.
