Again, I suggest you do a post grad year at a prep school in the United States. It will give you time to take the needed chemistry and math courses you need to take. It gives you time to prep well for the SAT and maybe take the ACT as well. It might raise your gpa as well.
I just don’t think you are set for success with admissions for NYU, or with high school courses where you can take the necessary pre med courses.
Also, for now… don’t think about medical school. Think about your path to get admitted to undergrad school…and please cast a net wider than NYU.
