I always like making a to do list, especially on a super busy day because it helps me feel less stressed and I can visibly see what I need to get done.
Or ask your professors to look over an assignment to make sure you are on the right track.
Also, don't be afraid to ask your friends to look over your work or to edit things for you.
Meet new people, attend things you never thought you would, take a course you wouldn't normally pick and just enjoy every moment you can because it goes by quick.
