Most courses will begin with a quarter of an hour of summary and then plunge into the bulk of the material. Depending on the field, there will be more or less exercises with a lot of learning at the level of self-correction to first offer independence to the participant, based on habits and repetition, and then to allow the learner not only learn from these possible mistakes but so that he / she is, subsequently, able to correct them by him / herself. The courses are in total immersions of the requested field and if the student is motivated, I can give complementary exercises to do at home.
