I'm currently a second year student in maths and I want to apply to some REUs but I haven't made any remarkable relationships with my profs or anyone in the department. As well, I've just been an average student, just As and Bs, so I don't have anything exceptional to show for my attendance in my profs' classes. Thus, if anyone has any advice on what I can do for LORs, I'd appreciate it.
Additional info: I am doing research in my university, just not in maths, it's in pedagogy, but my supervisors don't know what's going on in my classes. I also have emailed this great prof I had last year once this year and have asked her for an LOR already, but I don't know how wiling she will be to give me another one since it's been a couple of months since we've last talked.
