I am a fourth-year student who graduates in May and I only realised mid last year that I was interested in graduate school. Unfortunately due to my shyness, I didn't get to know most of my professors very well. This is exacerbated by the fact that all my classes are online which makes it even more difficult to connect with professors. I also cannot find any research opportunities related to the field I am interested in on the university career website.
Is it too late for me to get recommendation letters from professors?
