I am taking 18 credits this semester including:

5 - organic chem + lab
4 - calc 3
4 - CE 212
5 - physics 2 + lab

I also want to work around 20 hours a week and join a club.
I can’t really drop anything and alot of my hours at work will be on the weekends. Should I work less hours? Or could I be fine? I could also not join the club.
