What about your other applications? Still have any other irons in the fire other than LECOM??
As for LECOM, I would call to "see if they got your letter of intent"(although really what you want is an application status check). Then if they say they've received it, ask if all the seats are full yet/are they dipping into the waitlist yet. It's getting close to that time.
You know the saying, "Hope for the best, but prepare for the worst"? Sounds like your GPA will improve after this semester, and working as a CNA will be an invaluable experience (I did it for over 2 years and LOVED it), both of which will help your application for next year if you don't get in this year.
You might have to prepare yourself for the fact that you may have to retake the MCAT come April. For me, it was my saving grace after being rejected one cycle. I can't remember what your score was, but if you could get it to 30 or so it would help immensely. It is said that numbers don't matter in the DO applications game, but don't be fooled. TUCOM-MI gets 4000 primaries and only sends out 2000 secondaries. What do you think determines who gets secondaries? Extracurriculars? Nope. It's GPA and MCAT, simple as that. When the committee meets to vote, what do you think they discuss? Yes, extracurriculars and life experience, but they also want to admit someone that will make their school look good on paper, in the same way that YOU want yourself to look good on paper. They want their GPA and MCAT averages to go up every year, so that they can attract more competitive applicants.
I didn't get any interviews the first time, and frankly I didn't DESERVE to get into medical school that year. Why? I hadn't proved to them that I could handle the rigors of the medical school curriculum. Many will say that there is little to no correlation between MCAT and medical school performance, but many studies have been done that conclude that in fact a correlation
DOES exist.
I guess what I'm saying is that between two admissions cycles there is very little time to drastically make changes to your application. The best way to breathe new life into your application is to retake and do VERY well on the MCAT. If you started now you would have ample time to reach the 30 mark. Two months or so doesn't SEEM like a lot, but trust me, it's about the perfect amount of time.
I hope for you that you DON'T have to retake, but what happens if suddenly it's July and you've still heard nothing? Suddenly you're already a month behind those that turned in their 2007 applications! Assuming the worst, the other thing that you can do to get an edge is to have your AACOMAS submitted no later than the second week of June, your secondaries turned in and complete no later than the end of July, and I PROMISE you that you'll have an acceptance in hand before Halloween. That's a treat you can REALLY enjoy! Best of luck to you. Sorry this post is so long.
