I'm a rather shy person (maybe not so much on the Internet), and I haven't bonded much with many of my professors. Would it be better to have a third recommender who knows me well but is a humanity professor or someone is a math professor but remembers little about me? Also, my first and second recommenders can probably attest to my skills/styles in class or in research.
Thanks a lot!
I don't think that's a good option, if it is physics professor then it should be fine. But humanity…is just too far away from math.
