Hello! I plan on reapplying to DO and a couple MD after a post bacc I’ll complete by summer. During this time I have gained two LOR from a DO from being a CNA and MD from research, as well as a professor. I wanted to ask if I should ask my old LOR writers from undergrad (3 professors) for this upcoming cycle. Do I need them? Would it be good to ask because I had a good relationship with them or is it bad because it’s been 2 years? Is the 3 I have now enough? Or do I need maybe 1-2 more professors?
