The GMAT Barcelona (TLA) course has been essential to prepare for the GMAT. The classes help you to understand all the syllabus that you must know for the exam and above all to prioritize the most important points, which is key to managing your preparation time well so that GMAT does not become an impossible task. In addition, during the course of the classes you have the opportunity to see in what aspects you are less strong and you have to apply yourself more, and the specialized teachers are of great help to explain 'tricks' to minimize failures in those more complicated questions that are more difficult for you to solve.
Its PTC platform (Practice Test Center) is a very good tool for simulate the exam and practically in real conditions to finish polishing your skills and get a good grade. There are other platforms where you can take online exams but in my experience the PTC from Técnicas Lingüísticas Aplicadas It is one of the best in terms of difficulty of the questions, similarity to the real exam, possibility of analyzing the results and value for money.
