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.
Answer: For fall admissions, you should plan on taking the GRE in October of your senior year. If you miss October, December might also work, although some schools may not get the scores in time. (It can take as much as six weeks for the scores to become available.) Many application deadlines are early to mid January. However, a few are mid December. For spring admissions, contact the particular graduate school.
