Does your GPA matter if you already have a potential research advisor in the wings?

I ask because I realize that I may struggle when applying for graduate schools. It looks like I will do a masters after undergrad, but I will apply for a PhD in the future nonetheless. I have read that if you reach out to a potential advisor, and they agree to advise you for graduate school, the requisites of grad school admissions are largely redundant. Is this true?

  • Where is this happening? And the field might matter also, especially if outside the US.

  • Oh, I apologize. I remember reading it somewhere (might have been a CS prep guide for admissions into graduate school?) but I do realize that they may have been mistaken Feb 6, 2023 at 22:46

    A summary of my answer here: academia.stackexchange.com/a/192702/63475 would be that, for the US, having a supportive advisor (supportive = will pay your costs) will allow qualified students to be admitted to a graduate program that is only unable to admit them otherwise because the program doesn't have enough money.

It does matter. An advisor can strongly encourage an admissions committee to accept you, but the ultimate decision belongs to the committee. That said, it also varies a lot from country to country, and from institution to institution.

For instance, Canada tends to be on the harsher end about this, and you can get rejected even with a supervisor batting for you if your GPA is below their required minimum. I know two people for whom it was the case, and in both cases their GPA a bit over 3.0 on a 4.0 scale, while the programs wanted 3.3 minimum.
