Large public school, ~2400 students, 20+ APs offered (I think).
Senior year:
AP English Literature: First semester = 3-5 hours every night (...this is with decent time management). Second semester = 0.5 - 1 hour every night.
AP Micro/Macro: For both, 2 hours before quizzes/tests. 15 minutes for homework.
AP French Lang: What a joke. 30 minutes before tests.
AP Euro History: Slacker class. 2 hours before tests.
AP Physics: 4 hours before tests. 2 hours on webassign if applicable.
ECs: Usually get home at 6 PM on Mondays, Tuesdays, and Wednesdays from ECs.
Sleep ~2 AM. I write, and most of my inspiration comes between 12 and 2, so... Time management skills are decent; was a bad procrastinator until last semester when AP Lit forced me to give up on my procrastination tendencies. Otherwise, I would not have gotten any sleep at all. Also, I nap 2 hours after I get home from school.
