Each course unit is accompanied by a number of questions. Answering the questions ensures that the student has read, watched and listened to the content. Most importantly, these comprehension tests confirm that the student has understood the course unit. Each unit has to be passed in order for the student to progress to the next unit. Accreditation for passing the course is available from several governing bodies. These include internationally recognised organisations such as the Registro Profesional de Tennis (The Registry of Tennis Professionals or RPT). Based in Madrid, The RPT was responsible for the training of Rafael Nadal and Andy Murray.
