Will I hurt myself if I take the AP Exam and not the class?

Sorry, the title is a little click-baity. My school doesn’t offer AP Chemistry, but I really want to learn about it. I’ve already taken regular chem. Anyways, my problem is with my schedule. I currently take four AP’s (Physics 1, Biology, English Lang/Co, and Psychology)(I also take honors Pre-Calc). Anyways, if I were to self study Chem, I would drop AP Biology and just take it senior year. I feel like with everything going on in my life, I wouldn’t have time to self study chem. However, if I drop AP Bio, then I would have more time to study it. Overall, I’m just afraid that it’s going to give colleges a bad impression of me, like I didn’t choose my courses wisely. Senior year I’m taking all AP’s, so I’m not too worried about that. Sorry if this was a little messy, long story short I can either keep AP Biology, and end up not taking AP Chemistry in my high school career, or study AP Chem this year and take AP Biology next year.
