GAMSAT is available to any person who has completed a Bachelor or an undergraduate honours degree, or who will be in the penultimate (second-last) or final year of study, at the time of sitting the test, or, in the case of applicants to University of Exeter Medical School and Plymouth University Peninsula Schools of Medicine & Dentistry, who believes he/she has achieved an appropriate level of intellectual maturity and subject knowledge to meet the demands of the test. *The test is also for those for whom it will be more than two full academic years from the time they completed their level 3 (A level or equivalent) studies. This includes all graduate applicants (*The University of Exeter).

The GAMSAT test is offered twice a year, in March and September. To sit GAMSAT a test taker must be a bona fide prospective applicant to a course for which GAMSAT is a prerequisite.

There is no limit to the number of times a bona fide test taker may sit GAMSAT.

Test takers whose first degree is in a non-scientific field of study can still sit GAMSAT and succeed in an application for admission to one of the graduate-entry programs. A science degree is not always a prerequisite and institutions encourage applications from test takers who have achieved academic excellence in the humanities and social sciences. However, it must be stressed that success in GAMSAT is unlikely without knowledge and ability in the biological and physical sciences.
