Why is the test-maker not offering the GRE in the month of August?
For administrative reasons, there will be gap in testing from July 31, 2007, to September 10, 15, or 16, 2007 (depending on location). The test-maker has announced that this policy was adopted for administrative reasons, and because they will need a large volume of September test takers in order to create an accurate scoring scale in November.
