There is only one place to book your theory and practical driving tests and that is through the official DSA website. Destiny Driving School has links to these on the homepage under Useful Links and, unless you want to pay too much, the DSA website is the only place you should be visiting to book these tests. £31 and £62 are what you should be paying for theory and practical tests respectively. The DSA have already informed Trading Standards and the Advertising Standards Authority and feel that these sites are misleading consumers and tricking them into paying extra fees. Please use only the following addresses:
