so I have 3 choices in my area for graduate school(mathematics). Currently, my gpa is not the higest, so the letters of reccommendations are very important to me. I want to apply to all 3, and and depending on which one I get accepted into, I can choose. How do I handle my letters of reccomendations from proffessors? I'm not close to my profs at all, but I do have 2 or 3 that I think will be able to help me out a bit. Do I ask them each to write 3 letters, one for each school? how do people usually handle this type of situation?
