You can definitely balance it. I don't mean to sound conceited, but I'm juggling other things apart from university and work, and I can still manage my time. Everybody can manage their time if they believe they can. In fact, getting a job might increase your school performance because you'll slack off less. For example, if you know that you have work 4-11 PM
, you'll be more pressured to finish your homework early and fast.
I don't necessarily have advice how to balance it, I think everyone just finds their own way. It might take bit of time to find out what works for you
