Ya...I had a bunch; all of them were blended together into my committee letter. What helped me is I always took advantage of office hours and talked to professors. I wouldn't just go talk to them about school though; I would just ask them about their weekends and just talk like I would talk to a friend. In fact, some of my professors I can consider friends. They have given me such great advice, and even after I applied, I still pay them visits to say Hello. I also actually became great friends with my dentist. We often go out to eat and just hang out whenever I come home from school. Although I wasn't the strongest Biology major at my school, I got the highest recommendation, which I think only 2 others received out of our class of 20. I attribute this to the fact that I often communicated with my professors in formal and informal situations. Dentistry is a field that requires great people skills, and if you can show off those skills with your professors, then they will write you great recommendations.
