How do you survive junior spring?

So I go to a really competitive prep school. Everyone’s always secretly trying to outdo everyone else and it is super stressful. I’m a relaxed person so the prep school energy really isn’t my thing.

My school does trimesters, and I had to miss the first week of this spring’s trimester for sports, which didn’t really set a great tone for this term. I’ve caught up on all the work, but I definitely feel like I am doing worse this term than in the winter/fall. I play a varsity sport and I am taking AP math, AP physics, and AP lit. I’m also taking Chinese which is so hard. I also need to study for the ACT. I don’t want my grades to be worse than my winter term grades, but I can feel them slipping. I’m feeling tired and kind of burned out at this point.

Do any of you have any tips for surviving this term? Any thoughts would be appreciated.
