Good afternoon ... I needed to know if I need some instruction manual for the theoretician to do the exam. And if I need app.to give it up.and the cost.

Yes, there is a manual in Spanish and in English you can withdraw it in any office is free or download it from the agency's website. The exam is free the first time, if you scrape you must wait 24 hours to re-submit it and it has a cost from that second time plus the cost of the license process. You do not need an app to present it in the offices, there is a space with computers to present it, you can not use a phone during the exam, but you can run the risk that you will not be able to continue doing it. They are just simple selection questions with a specific time to respond. If you spend the same day you can take the practical exam

Look at a manual, but better go to the office for better information, as far as the cost I think they are 35 ..
