THE THEORY TEST IS ABOUT TO CHANGE.......
From 7th April 2014 the foreign language options for theory and practical tests will cease. The only available theory test voiceover languages will be English or Welsh.
The option for an interpreter to be present in the car on a practical test will also cease.
There is also an article from the DSA about copycat websites offering to book theory and practical tests. These sites are not sanctioned by the DSA and will charge you more than the face value of the actual test.
The DSA theory cost price is £31, and the DSA practical test costs £62, beware of any site that charges you more.
