I would encourage that route. I hated the 400+ student science classes at BYU. I didn’t do well in that environment.
I ended up taking my o chems down at SUU over the summer right before I took the DAT. A class of 30 students and it was awesome. And the only way I ever got into dental school was because I got a perfect score on that DAT in the o chem section. I guarantee that never would’ve happened if I took that class at BYU.
