It somewhat depends how selective your college is, and where your stats fall within their typical admission profile.
But the short answer is: Not. (You can do that when College starts, when you only have a few classes each week).
Being done with applications, essays, etc., and not having the anxiety of admissions/rejections, and not having your parents and guidance counselors breath down your neck, should be “relaxation” enough.
Then continue with roughly those grades for a little while longer.
Basically, you cannot suddenly fall into a “rabbit hole”, because the college is expecting you to be essentially that same high-performing student come May that you presented yourself as when you had applied.
If you’re taking AP classes you’ll have to keep your efforts up and get the best possible AP score, in case your college allows you to use those classes towards credits or for placement.
