I will tell you this from a student's point of view. Not from an adult who already finished school! They don't know how we feel because they pay them to do it!
We have half the year in school! 5/7 days of the week I have to attend school to learn things I am never going to need when I grow up and will easily forget in a couple of months! I say lower the amount of school days by at least 20. Because believe me, simply one extra day can help you study for a lot more than having 6/7 periods in school!
As psychologists have said, forgetting is when other material interferes with the learned material.
School is a really stressful place where you go for 7 hours a day. Not to mention having more hours of doing homework even after you leave the school!
It's time we have rights. Not paid adults
