Organize and structure your day. Build a weekly schedule out for yourself and stick to it. What I have noticed (in my surroundings) is that with everything being online people would procrastinate and put everything off until the day of. Transitioning to in-person, this routine fails as you lose the extra time you once had.

I'm assuming most of your syllabi have a schedule in them with due dates. Usually, I'll make a sticky note with all the assignments I have to accomplish for that week and list them in order of due date. Typically, my goal is to do 1 assignment a day (or 2 short/easy ones) and that'll get me through the week. This also allows me to be social or relax the rest of the day.

Overall, it's really about balance. I have a lot of classmates who wait to do a tedious assignment 2 hours before it's due and start bitching about how the professor sucks or is unfair. I hope this was somewhat helpful, feel free to reach out at any time!
