A quick briefing

Make a daily discovery.

A short daily refresher of MCAT knowledge and reasoning. Five original questions. Four choices each. One from Chem/Phys, Bio/Biochem, Psych/Soc and CARS, plus a rotating fifth. Everyone plays the same set on the same day.

1. Read the passage or science scenario, then choose the best answer.
2. Move between the numbered tabs. You can change any answer before submitting.
3. Answer all five and submit your verdict. Each correct answer earns one point.
4. Open each question’s review to see the correct answer and why it works.

One score. Plenty to learn.

Your first submitted attempt is the scored result for that day. Afterward, practice as often as you like; practice never changes your original score or stats.

A daily habit, at your pace.

Aim for 5–10 minutes; there is no timer. Difficulty labels describe questions within this daily game and are editorial, not exam-calibrated. New questions arrive at midnight in Edmonton, Canada. Completing the set on its own day adds to your streak. Past sets are free in the archive and count toward accuracy, but cannot fill a gap in a daily streak.

Keep your thinking.

MCATdle uses original practice questions and is independently made. Five questions cannot predict an MCAT score.
