The courses will be structured in this way: - Answering the student's questions - Course questions to answer - Help with homework - Identification of gaps and explanation - Some additional exercises to consolidate the basics, better integrate the theorems, know when and how to use them and ensure that the student has understood the work required. Of course, each student will go at their own pace, the important thing being that everything we cover in class is acquired. With work and perseverance, the results will be observable! Courage !
