I’m currently a 4th year Biology major thinking about potential recommenders to write red letters for med school. The two professors that I took Physics with know me pretty well, I did very well in their classes, and I’m fairly confident that they will be able to write solid letters. Is it bad to have both the science LOR’s coming from professors in the same discipline? Although I know one possible Bio professor I could ask for a rec, I don’t really know him that well and I feel kind of iffy about asking him for a rec. It’s not necessary to get a rec from a prof in your major right? Any clarity would help a lot - thanks!
