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.
You can view your official GRE Â® revised General Test and GRE Â® Subject Test scores online in your My GRE Â® Account about 10 to 15 days after your computer-delivered test date. If you take the paper-delivered test, your scores will be posted approximately six weeks after your test date.
