The DIAmond Advanced test
Administered by the Driving Instructor's Association of Great Britain (DIA), this test qualifies you as a DIAmond Master Driver.
The examiners are driving instructors who have received special training from the DIA.
The DIA test is structured in the same way as Part-Two and is marked to a similar standard.
If you want an in dependant 'mock test' the DIA test is probably a good starting point because of the similarities with the DVSA test and the fact that you will be tested by an instructor who may offer valuable advice.
