Early action vs regular decision if mediocre GPA?

Is it better for me to apply nonbinding EA, or to try to gamble on my senior grades going up? or is it better to apply now?
I have a 3.4wGPA, but this year I’m taking 2 AP classes, CS and stats. CS seems to be a hopefully easy A (my only regret is not taking this class last year), but for stats i’m getting B or borderline B-. 2 regular classes with Bs, another with an A.

idk if colleges don’t count orchestra in my GPA. that’s my easy A and if they don’t count it I’m screwed.
