Do you have difficulty not understanding your course in mathematics or physics? Do you want to prepare for your exams and need to review your methodology? I have the effective solution to overcome your difficulties. Courses are structured according to the following steps: 1. At the beginning of the session, I check with the student if he has done his homework and exercises requested by his teacher and I answer the questions he may ask. 2. As a result, I repeat with the student the badly assimilated course points by practicing some exercises. If the student has control, I revisit with him at the table his old homework and controls to achieve better results at the next control. 3. I ask the student to do some exercises so that he can put into practice the notions he has seen in class and take control of the working methods seen together. 4. At the end of the course, I give the student a summary sheet that includes: at. The notions to know b. Some typical examples to remember c. Tips to remember the lesson 5. I give some exercises of a level of difficulty similar to those discussed during the course to allow the student to review alone the notions seen together and to assimilate his course durably.
