LoR from science professors
I know that generally most if not all dental schools require letters from 2 science professors. However, I was wondering if they HAD to have taught you in a course in order for it to fill the requirement. I’ve been volunteering at a research lab at my university for 2 years now and wanted to ask my PI for a letter but I’m not even sure if it would count for anything because I never took a class he taught.
