A small collection of GRE FAQs

ETS (Educational Testing Services) is the authorized owner of the GRE.

The General Test is given year-round as a computer-based test in the U.S., Canada, and many other countries. In Nigeria, the test holds between two to four times every month in Abuja, Lagos or Port Harcourt. Paper-based General Test administrations are offered in areas of the world where computer-based testing is not available.
If you take the computer-based General Test, you can view your unofficial Verbal and Quantitative scores at the test center; however, because of the essay scoring process, you will not be able to view your Analytical Writing scores at that time. Verbal, Quantitative and Analytical Writing scores on the computer-based General Test will be available, 10 days after your test administration date, for dispatch to the institutions you designate to receive your score. You can also view your scores online.
If you take the paper-based General Test, you will not view any scores at the test center. Verbal, Quantitative and Analytical Writing scores on the paper-based General Test will be sent to you and the institutions you designate within four to six weeks of your test administration.
Although GRE subject tests are not mandatory, they test your knowledge in the subjects of your choice and thereby aid in making your profile more competitive. One must however check with their desired Universities about the GRE subject test requirement.
