When exactly is one supposed to begin building relationships with their professors, and how? Thus far, I have not needed to interact with my professors beyond them merely lecturing me. I go, learn the material, write their tests, and that's the end of that. I understand that this is something that needs to be done, especially if I want to proceed with education post undergraduate. Professors are exceptionally busy, and I don't see when this "relationship building" is supposed to occur given I have nothing to really talk to my professors about. I suspect that my grades will not be an issue, it's merely the letters of recommendation that worry me.
