Anybody have advice for time management?

Im in school from the morning up until 6 pm. I struggle with the acads, not that im dumb as hell, but im just particularly slow and i fear that i wont be able to catch up. The teachers would say all this things about taking it easy since stress is a big thing and students like me get easily depperesses nowadays. But i cant help but get stressed especially when we have if not 4, then around 3 assignments each day, which i struggle to find time for as i help out a lot on the house. And also probably the guilt because I dont play my games anymore
