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 scores are available online approximately 10 to 15 days if you took the computer test. GRE scores for paper tests are available six weeks after the test date. You may view your score for free online, but you must pay a fee to receive your GRE score by phone. Test scores are valid for five years. If your test was taken longer than five years ago, it won't be possible to obtain a copy of your scores.
