In the discussion on graduate school admissions, the consensus is that GPA is generally more critical than GRE scores, especially since many programs, including prestigious ones like MIT, no longer require GRE scores. Admissions committees tend to prioritize research experience and strong recommendations over standardized test results. While GRE scores can help compensate for a lower GPA, particularly in cases where applicants have strong subject test scores, a solid GPA is often seen as a more reliable indicator of future success in graduate studies. The importance of GRE scores can vary by field; for instance, in physics, subject GRE scores may carry more weight, but in engineering, they are less significant. Overall, poor undergraduate grades are viewed as a significant barrier to admission, while lower GRE scores may not be as detrimental if the applicant has a strong academic background and research experience.
