DAT practice test

Here are 20 free DAT-style questions we wrote ourselves, covering biology, general chemistry, organic chemistry, reading comprehension and quantitative reasoning. Perceptual Ability isn’t included, because those questions are all diagrams. The DAT has no pass mark, so aim for 70%: 14 out of 20. You’ll see why each answer is right, and you can ask the tutor if it still doesn’t click.
