Your AP exam takes 3+ hours. What you eat the night before and morning of matters more than students realize. Here's what to actually eat — and what to skip.

Night Before

  • Eat: Protein-rich dinner (chicken, fish, lentils). Complex carbs (rice, pasta). One vegetable.
  • Avoid: Heavy fried food, late spicy meals, anything new to your stomach. Stress on the gut = bad sleep.
  • Skip alcohol entirely. Yes, even if your buddy says one beer "helps with nerves."

Morning Of

  • Eat real protein: eggs, Greek yogurt, peanut butter on whole grain toast. Protein stabilizes blood sugar for 3+ hours.
  • Add slow carbs: oatmeal, banana, berries. Quick-release sugar = crash 90 min in.
  • Hydrate but don't overdo it. 12 oz water + breakfast. More = bathroom break panic mid-exam.
  • Coffee if you usually drink it. Otherwise skip — caffeine on a non-tolerant body = jittery handwriting.

What to AVOID Morning Of

  • Sugary cereal (Frosted Flakes = energy crash by Question 30).
  • Donuts, pastries, pop tarts (same crash, plus stomach issues).
  • Energy drinks (Red Bull, Monster) — heart rate spike messes with focus.
  • Anything you've never eaten before. Today is NOT the day to try kombucha.

During the Break

  • Bring: a granola bar, a banana, a small water bottle.
  • Skip: sugary candy, soda, anything that requires utensils.
  • 10-15 minute break is short. Eat your snack, sip water, breathe. Don't review notes — your brain needs reset.

What Doesn't Matter

Don't stress the "perfect" exam-day diet. The point is to eat normally, not crash mid-exam, and not introduce new variables. Stick with what works for you on regular test days.
