I agree with many comments above. You are a very strong candidate, and I think that you have characterized your schools appropriately. I think that you have a chance at any school that you have applied to, but that reaches are after all reaches. My guess is that you are likely to get into a reach or two.
I understand that most students who start off as premed students end up doing something else. However, it looks like you are serious about premed (for example you already have some medical experience) and you should plan finances to keep medical school open as an option. You might want to figure that medical school will cost $100,000 per year by the time that you get there. If you can get an MD with no debt that is great, otherwise you need to minimize the debt as much as you reasonably can. Thus you should definitely plan on avoiding debt for your bachelor’s if it is possible and it would be even better if you can save some $$ in a college fund (or your parent’s bank account) that you could use for medical school.
I think that you are doing very well. You might very well get into BU in the ED2 round which might make the rest of this moot.
When you start university, expect your premed classes to be significantly more challenging than anything that you have seen up to now. Classes will be full of strong students and exams will be challenging. I think that you can do it, but be ready to work hard.
