Schoolwork: 15-30 hours
ECs: 35-45 hours-ish depending on the week
Studying for SATs/SATIIs/APs: 0

Don't believe in it.
Exercising: 4-25 hours... this overlaps with ECs sometimes...
On CC: between hw assignments and randomly..
Watching TV: depends on the week..
Reading: For school, I counted under schoolwork, otherwise... I don't read much except for school breaks and summer.
edit: The number might seem a bit skewed, because I often miss school for ECs, and then count make up time as schoolwork, and I don't sleep a lot on weeknights.
