Agree about Tulane.
few suggestions OP:
-MUSC has a huge IS bias (only around 14% OOS matriculants). Of those 14%, the vast majority have strong ties to SC (attended undergrad in SC or used to live/work in SC).
-Brown is mostly BS/MD w/ only a small amount of direct entry seats available (~50). B/c of this the average GPA/MCAT stats are misleading and it's very competitive to get in esp. w/ no ties to the school.
-Commonwealth's mission is to train rural primary care docs for NE PA. They look for apps that have demonstrated a strong desire/committment to work as a PCP through their ECs and PS.
-Be aware that GT and GW get over 12K apps/yr and have very $$ secondaries. GT looks for apps w/ a strong history of non-medical community service in underserved communities. They also like apps from prestigious undergrads (Ivy/top state schools).
If your MCAT stays ~28, you would likely be more competitive and have a better shot at places such as:
UA, UA-Phoenix, Toledo, Albany, Creighton, SLU, UCF*, USF-Select*, VCU*, and EVMS*
If you can get your MCAT up to 31+, you would also have a decent shot at places such as:
Colorado*, Wisconsin*, Rochester, and Iowa
(* programs that prefer apps w/ heavy leadership and clinical experience)
Definately apply to all IL state schools in addition (and Loyola, Rush, RFU).
Don't worry bout undershooting your EMS director time comittment. As long as its not something ridiculous (like 70+ for student org) or adds up to more hrs than there are in a wk w/ school+research, u should be fine. (I worked full time as a FF/medic Lt. during undergrad [3-24hr shifts, 72hrs/wk] along w/ non-clincal volunteering+research) Its your biggest strength, use it to highlight your time-management + leadership skills.
Do you have any non-medical community service besides the EMS? If not it would help to get some and it would make a good update letter for schools.
Good Luck!
