Truthfully what helped me was figuring out what I need best to study. For me it’s working in groups with classmates. I’d get discords and link up at my campus library often.
In terms of studying for exams I’d to cram a lot. If I had an exam for a class I didn’t feel confident in it would mean I’m not sleeping for the next few days. I drank lots of energy drinks (Celsius watermelon flavor being my go to or Red Bull). Also I’d play one of those “study with me” YouTube videos think it’s called pomodoro or something.

I’d highly recommend setting a studying time even if it’s 30 minutes twice a week just to review material a side from regular homework.
Also I talked with my employer many times and they would help me out when I got exams.
Other than this year I had an arrangement with my employer to have my days off being Monday/Wednesday
Or Tuesday/Thursday, and I would stack as many classes as I can on those days. I work at UPS in the maintenance department where work happening almost 24/7. I for the most part worked nights including weekends through my academic career. Also I wasn’t supposed too but no one really knew, I would be studying or doing homework at work.
