Remove the 4 o'clock due date
The teachers can finish the homework work in 30 minutes, but we are just kids, it takes us hours, and the due date forbids us to have time. Most of us kids have some kind of extra curricular activities after classes end, yet only some are lucky enough to be 1st 2nd 3rd 5th 6th or 7th period where they can finish their work during lunch break unlike 4th period which wouldn't even have a chance to do it at lunch. We have extra curricular and homework for 7 other classes too. We get overwhelmed. We might unexpectedly have to go somewhere where we come back after the 4pm deadline. We use our time to do homework, yet there is no time to study for tests. We often find ourselves finishing our homework at 6, 7, even 8pm!
This is why the 4PM due date should be abolished.
