All our apps contain all revision questions, answers and explanations, licensed by DVSA (the people who set the test).
DVSA no longer publishes the list of exact questions which will appear during the test. Therefore, all apps on the market, including those by DVSA, contain only revision questions.
From our experience more than half of the questions in the revision database tend to appear during the actual test. Others are somewhat rephrased, but their meaning is left unchanged. Overall, you will have no problems passing your real test if you study using our apps!
