don't hand in anything late. if you do, your mark will drop faster than a brick in water.
you don't need to be there for every class, but you do need to keep up to date. if you aren't already, check with teachers for any assignments you might've missed, or upcoming assignments you might not know about. if your school uses blackboard or another mobile app to update grades and assignments, use that shit so hard.
if you can afford to live off campus, i suggest doing it. it'll cut down your debt later in life, especially if you're living with a friend, relative, or S/O. only live on campus if you don't have any other alternatives.
learning to cook for yourself is key if you plan on living by yourself or with a friend, and get creative. you may end up living on noodle cups for a couple weeks, so don't stress about it, try and think up cheap dishes to eat, and include the food groups if you can. healthy diet is key to productivity.
overall, don't slack off and make sure you keep handing in your projects and workloads on time and you'll be golden. watch your money and keep everything as cost efficient as you can.
good luck with college, bro <3
