1 Total Time: The computer-delivered GRE takes 3 hours and 45 minutes for the average student.  Experts recommend sitting for the GRE exam one year prior to entering graduate school. This allows for ample study time and the option to retake it if desired.
GRE Cost: $50 ($53.90 in China) You are charged this GRE price when you change the date and/or location of your test. You must do this at least four days before you were originally scheduled to take the exam (and at least ten days if taking the test in China). If not, youâll forfeit your entire GRE registration fee.
