Hi all, I'm sure this subject has already been posted before, so please forgive me if this seems like a rehashed post. I know from google searches what the GRE is, but how exactly is it different from a physics GRE? And do I have to take both? I know that probably depends on what grad program I apply to, but is it better to take both anyways? I am planning to take them in April (so if I do poorly, I can retake them in November). Does anyone have any good book recommendations? I know the GRE changed this year, so does anyone have any books that they would recommend for the new version? If anyone has any tips, I would appreciate it. I know April is far away, but between work and school, I know the time will go by too quickly. Thank you for all of your help!
