MCAT Arcade makes studying feel less like studying. Answer real MCAT questions across all 5 subjects, build a streak, and unlock a quick arcade break to reset your focus. It's the study app that rewards you for staying locked in. WHAT'S INSIDE • 1,000+ MCAT-style questions • 5 core subjects: Biology & Biochemistry, General Chemistry, Organic Chemistry, Physics, Psychology & Sociology • Mixed Review mode — pull questions from all 5 subjects in one session • Detailed hints on every question • Spaced repetition — questions you miss come back until you nail them • Save tough questions to revisit later • Test day countdown right on the home screen • Customizable streak goal and hint settings • 6 arcade minigames: BrainBreak (block puzzle), Color Sort, 2048, Snake, Brick Breaker, and Bloodstream HOW IT WORKS 1. Pick a subject and topic 2. Answer questions, use hints when you need them 3. Hit your streak goal and unlock a minigame 4. Play, reset, and get back to studying sharper THE SCIENCE BEHIND IT Your brain retains more when learning is paired with reward. Every correct answer triggers a small dopamine hit, and earning a game break after a streak reinforces the neural pathways tied to the material you just studied. It's the same loop that makes games addictive — we just pointed it at the MCAT. Traditional study sessions fight your biology. MCAT Arcade works with it.
