honestly though, you are the one that put yourself in this position. Its going to take at least a year or two of proving to adcom you are worth it. Unless you have stellar MCAT's ... then maybe just one year of acing some upper levels would work. I my experience, undergrad advising didn't help much b/c if you didn't fit the cookie cutter of a premed they automatically discounted. If you want this, get clinical experience and improve your grades. Talk to some of the schools on how to strengthen your app. If grades were the issue, then work on them. I'm guessing with your GPA it was your grades. It also could be the trend in your grades as well.
Its not going to change over night and I hate to be blunt, but the sooner you see and accept that, the easier it is to take action and barrell ahead. I had a 2.3 gpa graduating and 2.5 overall. Its going to be tough but I'm expecting at least 2 years of undergrad. I talked to a few schools about my hole, one MD and one DO and they both said, GPA has to go up.
