This is fairly representative experience for high achieving students. When I was in high school, I was typically up at 6:30 AM to get to my 7:00 AM AP class. Classes can end anywhere from 3-4 pm, depending on your course work. After school clubs and activities ranged from commitment. But we were under the assumption that it mattered a lot for college admissions, so many of us participated in 2-3. Once you got home, you had a considerably amount of homework from each class. If you were prepping for standardized exams, you probably dedicated some time to study that as well. Overall, I felt the amount of time spent working in high school was taxing. But also it worked out for me - went to a good college and got a good job and life.
