I am a current SGU student studying to take my step 1.
I know people in my class you had a lower MCAT than you and also less EC than you. that being said- you should try and improve your verbal if possible, but even w/ your current stats- you are a good applicant for SGU. My MCAT was 13 BS, 11 PS, and 7 VR, and writing L, my GPA was 3.7. But, I know tons and tons of people in my class who had MCAT around 24-25ish and GPA around 3.0, and on the other side of spectrum did know tons of people with 30 + MCAT and GPA close to 3.9/4.0.
overall, i'd say you have a good shot at getting in as long as you are not a total act like a lunatic during ur interview.
