Questions students ask

Will this actually fit my schedule?+

Pick Light (~25 min/day), Standard (~45 min), or Intensive (75+ min). Intensive adds extra math-FRQ reps on signature days.

How much math is on APES?+

More than students expect - about 25% of FRQ points involve calculations (dimensional analysis, efficiency, half-lives). Students who skip the math section of the FRQ cap their score at a 3.

Do I need to memorize every environmental law?+

Know the big ones cold: Clean Air Act, Clean Water Act, CERCLA, ESA, Montreal Protocol, Kyoto Protocol. They come up in FRQ solution-proposals.

How do I practice FRQs if I don't have a teacher to grade them?+

Use the scoring guidelines on the College Board PDFs, or sign in to GradGPT for instant AI feedback on the exact FRQs in this plan.

APES FRQs reward specific examples - not general statements.

Write a timed APES FRQ. Find out if your answer names specific laws, studies, and units before exam day.
