Do I have a chance at a top medical school?

A little bit about me: I went to two different 4-year undergraduate schools (transferred out of the first one due to clinical depression). Let's call them college 1 and college 2 (the most recent college I am at). Currently a senior in undergrad, with 3 quarters left of school (hoping I can raise my GPA in that time). I am planning on taking a gap year and in that time working with a local community in a healthcare-related way. Race/ethnicity: Chinese, Mexican, White... Do I have a chance at a top medical school?
