Hi everyone, I'm planning to take GRE physics subject test probably around Fall this year. This is going to be my first experience taking GRE. I have some questions regarding this. If the application deadline in my desired university is somewhere in December, when should I take the GRE subject test (there are 4 test dates closest to December, all within September through November)? Second, what is GRE general test typically for? Does every US university applicant, regardless of their department aim, have to take the general test?
