panicking about ap chem 😭 help me

I’ve always been a very high achieving student and I’m aiming for T20 colleges. I’m planning on going into the medical field and majoring in biology for undergrad, and I’ve planned high school all around this. I’m used to being a top student in all my classes, I even took Calculus BC and I didn’t struggle. I don’t mean this to brag just as context— this year, I’m taking 5 AP classes, all of them are going fairly well (and I’m loving biology) but I feel so stupid in AP chemistry. Everyone in the class is doing very well, scoring 80-100% on the first test today. I had one of the lowest scores at 60%. I know chemistry is very important for med school so I feel so lost. I feel very embarrassed being in that class because I’m so used to being smart and I think I’m the dumbest one in there. Anyway the point is— is my future career doomed? Should I keep the class and just do my best to get through? I’m kind of panicking please help me figure out what I should do!

Edit: I guess my question was not so much if struggling in AP chem will cause me to have a lower chance getting into college, because it won’t reflect in my applications unless i say it explicitly, or if i get <5 on the exam (I’m most likely still going to have a 4.0 because of assignments and grade inflations lol).

My question is: if I’m struggling right now, will working hard get me where I need to be, or does this kind of ability only come naturally? Everyone in my class seems like they’re just naturally good at it and that’s what scares me— I was told because I’m good at math and biology i’ll be good at chemistry but I’m just not.

Sorry this is long I’m just confirming what my question was, thank you
