I graduated in April 2016 with a BS in Biology. I'm applying this cycle, but I'm not optimistic as I still haven't taken the DAT. Should I not get in, I will apply again and possibly start a masters program Fall 2018. I'm wondering if I'll have to worry about re-taking my prerequisites down the road as it will be three years between finishing my undergrad and starting dental school. Anyone with information on the matter would be helpful.
