High school is easy af, but you can definitely get away with not doing homework some nights. I feel like i had more homework and bitch assignments in high school versus college. Work on it in class when everyone is dicking around. Do you have a joke class? I used to do my math homework and whatever else I had during American government, and study for chem during math class haha. Do you play any sports after school? I used to do my math during the hour of waiting for football practice to start after school. Sure you can cheat, but that won't do you any good in the long run. Especially come exam time. Is your teacher assigning a book to read? Use spark notes and cram them right before the quiz. Is an assignment mandatory? If not, don't do it. If it is mandatory, then will the teacher check it? If not, don't do it. Just don't let things like up and be proactive. Pay attention in class so you don't have to study as much for the exam.
Take adderall so you can work faster and more efficiently? Or coffee.
