Dear butchh,
The universities u had attended interview are small programs with each university having their own criteria so just because x y z university did not take u it does not mean bu will not take you. I had bitter experiences before i got the acceptance into bu. My experiences with bu is that they never miss a person with strong credentials their only criteria of selection is a high part 1score (this is the most important and u have it) toefl score above 100 (u have it and other things are ur motivation (ur intrest in getting a dmd) they measure this partly by what u have done in ur country and what ur doing after coming to us. the easiest way to get experience in us is to go to a practicing dentist and make a request about your intrest in dmd program and intrest in learning the dental system here. dont stop at one clinic, i have visited at least 6 people before i got a final yes. do it right now. keep meeting dentists and make a request. believe me bu is different from others in selecting people, to make an example of their reaction to strong credentials. i got the call within a week of application and got accepted within 4 days of the interview and people who got accepted along with me had high part1 scores and came on b1 visa(they did nothing in usa at all) so trust me if u do not get better offers than bu i am sure i will meet u. good luck for making it to class of 2012
