Is getting into a top-tier medical school realistic for me?

Thank you all for the responses. I think you guys are focusing more on the fact that I said “top-tier” rather than just any medical school. Getting into a top tier school is my preference, not my focus, getting into ANY med school is the goal. I should have made that more clear. The main question I’m asking is whether I am on track to succeed in the medical school admissions process GPA-wise.
