Hi, (I'm not too sure where to post this but this seems to be the most suitable place. Apologies if I am wrong.) If I am majoring Astrophysics and applying to grad schools, is my Math gpa an important factor in addition to my Physics gpa , Astronomy gpa and cumulative gpa? If so, how important is it and what is the approximate minimum gpa I should be attaining if I wanted to apply to top tier schools? It seems to me that Math gpa is always related to Physics gpa, but I'm not too sure if it is considered as my "major" gpa. Any help will be appreciated. Thanks!
