Depends on your course load really, how much you're willing to take on, extracurriculars, study habits, social life, time management. It's easy for it to get overwhelming so either micromanage if you know you have a lot on your plate or lighten the load. Or do like me and try to do as much as possible then let everything else fall on the wayside. My life is basically a ping-pong of priorities, what needs the most attention now is the standard by which I take action and get stuff done. ? But that's not really the best course of action.
Noo, I enjoy being a student. Someday you'll miss the feeling when there's a news in tv about class suspension.
