The majority of medical schools use an admissions test as part of their entry requirements. There are three admissions tests. Medical schools each state on their websites which test they use. You might sit different combinations of these tests according to the medical schools you intend to include in your application.
The majority of medical schools use the UCAT (formerly UKCAT). Applicants register for and sit the UCAT before the UCAS application is made. Registration typically opens in May and closes in September. Testing takes place from July until October, ahead of the final deadline for UCAS applications to medicine, which is 15 October every year. See the UCAT website for exact dates and to register.
Some medical schools use BMAT. Registration for BMAT takes place between 1 and 29 September 2023. There is one test date for BMAT: 18 October 2023. See the BMAT website for free resources and practice papers to help you prepare for sitting the test.
This test is used for the Graduate Entry Medicine courses and for a number of the Standard Entry Medicine courses where the applicant is a graduate. As with the UKCAT, an applicant must register for and sit the GAMSAT before making the UCAS application. Registration is in August while the test is sat in September. More can be found on the GAMSAT website.
