Heather,
Well done on your mcat improvement! I am in much the same boat as you – lower gpa and improved 7 points on my mcat to 30+. This is my second year applying and I'm considering my state school along with a local DO school. For me it's all about location and the financial situation (married w/ 2 kids) – but that's another string.
Anyway, there's a lot to be said about that improvement. Have you spoken w/ any admissions people at any schools. I would suggest getting some face time. Since my last application, I've spoken with one dean in particular, and even though she isn't on the ADCOM, she will be presenting my application to the ADCOM and asking them to strongly consider my position in life as well as the committment I've shown. Point is, in speaking with her a few times, she has had the opportunity to get to know me and understands that I will be a strong candidate. Lots of other details I won't go into, but face time is very valuable.
Best of luck – one other question – do your grades show a strong trend toward better grades later – that is also a huge help and a good topic to discuss. Stay committed.
