Do not expect that classes will be any easier at a “top 10” university. One thing that happens when students arrive on campus at any highly ranked university: They discover that they have suddenly become average, they discover that they are surrounded by a very large number of very strong students, and they discover that classes have become difficult.
I am speaking from experience, having attended a “top 10” university (specifically MIT for my bachelor’s degree).
On the other hand, some students excel in some subjects and struggle in other subjects.
In terms of whether to drop the class, I do not think that university admissions would be anywhere near the top of my list of concerns. Rather think about what is right for you, and what is needed for you to graduate high school. Then find colleges or universities that are a good fit for what you have gotten done.
I am hoping that you have already taken regular chemistry.
