Don't worry: you set your own pace of progress. Indeed, the study durations of 20h00 indicated on the information sheets are only given as an indication. This allows you to adapt the duration of the training to your own schedule.
No rhythm is imposed: you can therefore speed up or slow down the duration of your studies. However, the Pedagogical Service recommends going through all the courses for adequate preparation for the RBQ exams and to increase your chances of success. Your results on the formative exams are a good indicator of your mastery of the subjects currently evaluated by the RBQ.
