The General Test is given year-round at computer-based testing centers.
Appointments are scheduled on a first-come, first-serve basis.
A candidate may take the General Test only once per calendar month and not more than 5 times within any 12-month period. This applies even if a test taker cancelled the scores of a test, taken previously.
