This is a valid point. One of my DAT instructors/tutors was a guy who had graduated from the Univ of Houston, travelled and worked a while. Later, he returned to another college and earned a 4.0 and eventually performed in the 20+ range on the DAT.
When confronted with questions (in the interview) about his first bachelor's, he commented that he wasn't serious and partied, but went back to school and proved he could do well academically then suplanted it with a very strong DAT.
Gavin is correct that additional courses should be included to help your cause along with any other things you could fit in.
I myself fell into a simliar category, since my first bachelors was in Communications (B avg). I spent 2 1/2 yrs taking a full load of science courses (A avg) and other activities to be the best applicant I could when it was time to apply. This was the advice I was given circa 2002, long before I eventually applied to dental school, providing time to improve.
Also, I was advised that it does matter what school you attend. This is what I found to be most questionable. Since not everyone can afford to attend a high end private school, it is weird that a school's reputation would come into play, but it does. At least, that is what I was told at Baylor by more than one faculty member. It seems that admissions' committees take note as to where you went to school and how you performed against arguably stiffer competition. From what I understand, Baylor is not alone in this caricature and that other schools do this as well even though it is not always directly stated.
I guess there really isn't fairness in anything. Man, I've got to stop watching FOX News (Damn O'Reilly). 😳
Admissions into dental school is not clear cut as I once assumed it was, but it is helpful to get as best an understanding as possible as to how the process works, which can vary depending on the school.
For example, the Univ of Detroit-Mercy states that it looks highly on the latter semester averages than those in the earlier college years. The reasoning provided in their literature is that students who performed marginally earlier on, are in a mathematical quandry as to being able to increase their GPA's. I had never heard that before reading UD Mercy's admissions requirement packet. Ironically, I did not apply to UD Mercy eventhough I debated on it greatly. In the end, I just could not see myself residing there for 4yrs and being comfortable. But that was a personal decision. Take care and GOD Bless.
