i had to respond about your parties with 27s comment b/c in case a pre-med reads this, s/he may not be as motivated to score any higher than that .. i just wanted to be sure of that b/c above all else, everyone should try their best .. i've known a few people who didn't take certain parts of their application seriously, and i wouldn't want to see current students make that same mistake ..
you originally posted "mediocre student" .. i don't see how you expected me to know that you have outstanding ECs (as you've just cared to elaborate, initially they looked ok) as i never consider people with many unique experiences as mediocre .. when you mentioned mediocre, i took it as average across all aspects of the application .. with your ECs, i would say you have great chances of getting into a TX medical school, and you shouldn't be concerned with "mediocre student" medical schools (and i'm not sure if you mean mid/low-tier by this) .. i've worked all through college myself and came out debtless as well .. so congratulations to you for that b/c i know how difficult that can be .. the adcoms have looked kindly upon that in my situation, although my grades didn't suffer .. but i'm thinking they would still understand in your case .. i don't understand why you're desperate if A&M cranks out so many accepted students with below avg/avg scores .. you're very lucky to have a great advising office (as my school didn't have such, which i believe would be the reason behind the differences in our data) .. i can't tell you if out-of-state schools are within reach if they do an initial screening process which does not take into account your ECs, but i'm assuming you wouldn't need to worry so much .. i'd be fairly confident suggested by the A&M data .. if i were you, i'd go ahead and apply anywhere i wanted if within my budget, because you just never know. to this day i regret applying to 2 schools, but live and learn.
i'm not sure if you've checked the threads i've gathered for you, which have many good suggestions for schools .. in the end, it can be a crapshoot .. although i wouldn't say it is in its entirety (someone can get 9/10 acceptances, and since s/he didn't get in the 10th, it's a crapshoot? to some degree maybe) .. but i would definitely say that since you are a very well-rounded person, you shouldn't become desperate .. and you're welcome
... and one thing about SDN, don't let anything on it piss you off .. take whatever we say with a grain of salt .. we're here to advise students, but obviously no one knows everything, esp. when we don't know everything about the OP .. and i would definitely not listen to other pre-meds who haven't gone through the process yet .. just another piece of advice that i had to learn
