I applied to dental school not medical school this year, but i was in the same situation as you. I graduated with my degree in 1998. None of my professors remembered me. The way my school works is they have evaluation sheets that your professors fill out, stating your rank in class, grade and how they feel you would perform in professional school. These forms are then sent to the main office where a composite letter is then typed and sent to the professional schools. I know they really can't say much about you as an individual, but you can always get letters elsewhere for that. I also had one sent from my current employer and another from my volunteer experience. Another option is to pick a class you did well in, then talked to your professor about your interests in medicine,goals,etc. Through conversation he/she could get to know you better and be able to write a more personal recommendation. Hope this helps.
