That's right - Tufts & BU. I forgot, they have combined programs too. Adding them to the list above.
I don't know really what they were looking for in high school to get accepted. I had good grades in high school, took a gazillion AP courses, and had a decent SAT score. At my program, they interviewed 5, accepted 3, and 2 of us enrolled. They definitely wanted to see some experience in dentistry b/c both me and my classmate had done some shadowing our senior year in high school.
To stay, we had to maintain a 3.3 (a joke at my undergrad) and earn a 17 on the PAT. Each year, the dental school administered this ghetto version of the PAT by itself to us and the international dentist applicants. The students now have to take the entire DAT on the computer, but only the PAT will be looked at for the program. We didn't have to apply through AADSAS or anything. Sometimes I feel like they opened the back door to the dental school and just let us in b/c I didn't have to go through too much stress or agony in college to be here. Our undergrad bio department was not fond of the joint-degree students. I felt like they looked down on us for two reasons: 1)We weren't staying the full four years to get the true bio experience - blah. 2)We were pre-dent and not pre-med, so we weren't bringing any pre-med glory stats into their department. I had a lot of professors convincing me to drop the dental thing and go pre-med.
It was nice going through undergrad without the stress of "Where am I going next?" I knew all along. The only regret I have is I never bothered to look into applying out of the program, so I'll never know what other options I may have had.
