A lot of other factors come into play during this whole process.
Whether or not you get an acceptance depends on your MCAT, GPA, ECs, LORS, Essays, PS, etc.
First off, your app is rather late and based on what you are telling me so far, you only have 100 hours of volunteer work? Any other ECs? You are just starting clinical experience?
What about your MCAT and GPA?
Also, your chances of acceptance can depend on the schools you are applying to.
