You are in preparation for this school year? (primary school, college, high school or university) and encounter difficulties in mathematics, physics and chemistry (misunderstanding of the course, exercises, inappropriate working methods)? Do not let the gaps accumulate and opt for quality support. With more than 250 students followed over the last 8 years and more than 6,000 hours of classes, I was able to refine my methodology to provide effective support and coaching adapted to the needs of each student. Following an initial analysis of the pupil's level, strengths and goals, I define with him / her an educational strategy in terms of improvement axes, working methods, frequency of classes and of media used. RUNNING OF A TYPICAL SESSION 1- Answer the student's questions (course points, exercises and corrections given in class) 2- Assess the student's comprehension (direct questions, direct application exercises, quizzes, validation of the student's cards) 3- Verification of the work required of the student 3-a- Identification of possible misunderstandings 3-b- Detailed explanation of questions not included 3-c- Correction of possible errors 3-d- Tips solving method and tips 4- For all the exercises / annals done together, the pupil is strongly encouraged to do everything alone and to write them on his own. The student is also asked to note any difficulties encountered as well as the time spent on each exercise. This approach aims to: 4-a- Validation of assimilation 4-b- Editor's rating 4-c- Evaluation of effectiveness (speed, absence of errors, etc.) 5- Summary item - Minutes of the meeting 5-a- What was done during the session 5-b- What the student could remember 5-c- What the student should do for the next session * I can give you references: students that I followed and who have integrated the most prestigious schools (ENCG, MEDCINE, ENSA ...). * Possibility of classes for several students at the same time (group classes) and distance courses (by webcam)
