Do u have these test weeks at school? In here our school year is divided into 5 parts. And after every part we have this test week. It's 1 test per day and then 1h of school. (the same class that the next days test is) There is usually like 1-2 days when ppl don't have any test because to have 1 test every day u would need to have 7 different classes. And one class is 5h/week.
I like the system very much. Actually I think it's awesome!
An average school day for me (normally) is like 8-14. Now that it's test week I go to school usually at 9. Then I do the test, takes 1-2 hours. Then I go home, and then I go back to school for that 1h, which is 12.15-13.00
So the total is about 3h of school per day.
So do u have stuff like this?
