Hit the gym

This is such an important one. Even if you think you don't have the time to go the gym, make sure you go. Moving around helps with concentration and gives you an energy boost when you're going back to study. If you've been studying by yourself all day, try and go to a class or workout with a friend for some social interaction. On days with no tests, you can workout at whatever time you want, so pick a workout time and stick to it, or just go when you need a break from study.

Make a schedule

Pick times for when you're going to study each subject, then switch to a new one after you've been studying for a certain amount of time. It is easy to burn out after reading about the same topic over and over again, so give your brain a break with a new subject. Making a schedule also helps with not feeling restless because there is a set end time for what you are working on.

Switch locations

If you start drifting off in the location you've been at for awhile, pick a different place. If you're at the library, go to a different one, or even pick a different floor or desk. The little walk over to a new place refreshes you and gives your brain a break from studying. I've been rotating between my favorite library, the lounge on my floor, and my dorm room to stop myself from getting bored in one place.

Grab a bite to eat it

Bring a snack to the library and take a short break while eating it, grab coffee with a friend, or go to the dining hall. You need fuel to study, and you also need breaks, so combine the two of them together. My new favorite snack has been Made Good Granola Minis- they are bite size and come in different flavors. 10/10 recommend the chocolate chip ones!
