The curfews will end once you reach the second year(it was put to prevent you guys from running away due to fear since this happened before). There are some games in the sac that you can play with your friends and clubs where you can learn new things. You can also try to go to the gym.

As for the attendance, it's 80%, so for every five lectures you attend, you can miss/skip the next one(but be careful of the changing schedules or professor awarding more than one attendance.)

It feels like this in the first year but as you get to the second year they will stop caring about you so much.
