I agree with seventy
I had a bit of a road to school, so going an hour to school for 3 hours is a waste of time. I usually skipped the days when I had less than 5 hours of school. An hour to school and an hour from school is 2 hours, and if it's just for 3 hours, it's wasted time. I had books that usually said the same thing as teacher in class.
Highschool should be only for people that want advanced education, not an obligatory. In elementary school people learn to read, count and do some more advanced stuff, geography, history, basics. But after that we know basics, we can read and count, we have books to teach us most of stuff and we attend school mainly to spend the time productively until you encounter a stupid teacher that thinks he is better than any of you. Well he's a teacher and you can become a president, who laughs now ?
Schools should always consider what difficulties some students have to even get to the school, be it elementary, high school or college/uni. Waste of time is waste of time.
