Ap classes

i have a question if you all dont mind. Im a sophomore in highscool now and I’m currently taking pre ap algebra 2 but im debating wether or not i should drop the class to on level since its quite stressful and i feel im not going to do well in the class. Im also taking pre ap geometry too and other various classes so dropping the class would help lessen the stressand perhaps i could get a better grade than staying in pre ap. But,Im conflicted on if i should drop because my friends who are taking pre calculus are saying that pre ap algebra 2 will help for both pre ap precalc and AP calculus. and since i want to pursue engineering ( perhaps biomedical specifically) taking math is essential and im afraid it’lll look bad to colleges to TAMU,UT and more if i take on level math classes and pursue engineering. What effects will taking all on level math classes in admission to college? What is more important, GPA or ap credits?
