I think they are still interviewing people with high GPAs
I think they have already filled the interview dates until early March..
However, there should be one more cycle.
That cycle should be mostly filled by people with lower stat..
This is the thing...
there are probably 800 people (if not more) with GPA below 3.4 and are waiting for an interview..
I have no idea how they are going to pick out 120~150 ppl from that pool
It varies from individual to individual (ie academic trend, ECs...)
Here are just some facts directly from USC Dental Website
The entering class science GPA is 3.45 and the average overall GPA is 3.40. Both GPAs range from 3.20 to 4.00.
Cross your fingers
and hope for the best
