I am applying to math graduate programs, have a list of schools of different range, but I am so worried about being accepted to a grad school, that am considering to apply to 20 schools.
My undergraduate institution is one of the top schools in math, #1 or #2 in several math fields.
My worry is that I messed up grades of some important classes, also totally messed up my gre sub, since I didn't prepare for it at all. But I do have lots of research experience in fields related to applied math (I want to do applied math, now I am pure math major).
Should I apply to 20 or there is no point in applying to so many, maybe just 15? I also don't want to disturb my rec letter writers so much. I am not thinking about the money I have to spend on the application process
Thank you :)
