If you're studying to take your driver's license test in Spain, then you'll need an application like TodoTest: Driving Test to help you review everything you learned in driving school.
This tool gives you access to hundreds of tests for permits like B, A1, A2, BTP, and ADR, with all the latest information and questions that have appeared recently on the DGT, along with explanations for each correct answer.
TodoTest: Driving Test is a good application for reviewing the topics you're less sure of as well as for broadening your knowledge of driving rules.
Besides helping you prepare for the test, TodoTest periodically checks all rule changes so it can offer updated information. It will also display specific warnings for these kinds of changes, so you can be sure about what the new standards are by the time you take your test.
