I wouldn't worry about it at all. Noemi really just wanted to look over the transcripts to make sure the pre-reqs were taken (or that they are in progress and will be completed before matriculation) and all degrees have been earned.
Absolutely nothing to stress over! There was no discussion over grades. Oh also it was done after the interview while we were waiting for the rest of the group to complete their interviews, taking, maybe, 2 minutes at most.
You've gotten the interview. Take a deep breath and try your best to relax and make it a fun experience. The chances of you getting in are extremely high.
All the faculty and staff were really, really friendly! There was definitely an emphasis on why dentistry, whether or not you'll be able to handle the stress, and making sure you're applying to dental school for the right reasons. Think through your responses on these topics and rock it!
