Some people are naturally brilliant and ace the MCAT without breaking stride, just as they ace classes they take. The rest of us have had to work hard to get the desired outcomes.
Other than those brilliant and very accomplished people, most apps are a mix of stronger and weaker factors. Schools are looking for the strongest applicants they can get in a process that is competitive from both perspectives. It sounds like you have some good positives on your record. If your MCAT doesn't come out to be as competitive as you'd like it to be, do a better job of preparing and take it again. Hard work and practice tests will improve your verbal scores.
