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.
At about the same time as your scores are available in your My GRE Â® Account, your official score reports are sent to the schools you designated. If you take the computer-delivered test, it is about 10 to 15 days after your test date. If you take the paper-delivered test, it is about six weeks after your test date.
