Several U.S. PhD programs in physics may waive GRE requirements for admission, as evidenced by personal experiences shared in the discussion. One participant noted that they were admitted provisionally to a program without taking the GRE, later becoming a PhD candidate after a year of coursework. This suggests that some institutions may offer flexibility in their admissions criteria, especially for candidates with relevant research experience. Another contributor advised that while some schools may waive the GRE, taking at least the general GRE could be beneficial and is often less demanding in terms of preparation. It was also mentioned that candidates should consider their current institution, as they may have policies that could accommodate students looking to continue their studies without GRE scores.
