    Private lessons in Math, Physics, Chemistry and SVT
    The courses of Mathematics - Analysis - Matrices - Statistics - Algebra - Geometry - Physics - Mechanics - Electricity - Chemistry - Organic Chemistry - Biology, and Geology of secondary or university levels (French, Belgian, European, or international programs) are given by explanations either in-depth either by a quick course and summary of essential need depending on the case of each student supported by exercises from the book or assessments and exams from other high schools. My experience is too long and for years I have learned methods for each case and for each student to fill in their gaps with the best results of Excellent, Very Good, and Good. I can also help students to better prepare for courses and support them to better prepare for the duties of CNED in science subjects.

    Excellence: Maths Courses - for College - High School - University levels
    ⭐⭐⭐⭐⭐ 👨‍🎓 With 4 years of experience in distance education, I am a mathematics teacher specializing in support lessons and private lessons. I also teach physics and chemistry as well as scientific subjects in general. I hold a Master's degree in Operational Research (Applied Mathematics) and I have been teaching private lessons for more than three years, mainly mathematics for middle and high school levels. ✏ I have taught students from different schools, whether public, private, following the French program (mission), Belgian, Swiss, Spanish (students from French-speaking or English-speaking Spanish schools) or American. In summary, all French or English programs. ✏ I support students from A to Z in all stages of their learning, using a simple, new generation and effective methodology: explanation of lessons, summary of lessons, application and deepening exercises, etc. ✏ I also prepare students for exams and competitions. ✏ I also support students with their homework (homework help). ✏ All my students have made extraordinary progress and achieved their goals, with grades of 16, 17, 18 or 19 out of 20. Sessions usually take place as follows: 1️⃣ The first sessions are mainly intended to assess the level of the student in order to determine the shortcomings noted. 2️⃣ Then we make a plan to fill those gaps: number of hours of work required, parts of the lessons to focus on, lots of training and development exercises, etc. 3️⃣ We make sure to stay up to date with the student's class teacher to track their progress and align our work with what is being taught in class. 4️⃣ Then I provide exams similar to what may be offered in class. 5️⃣ Upon request, I write a monthly report to keep parents informed of their child's level throughout the course. I also adapt my methodology according to the needs of each student, which means that everyone has a personalized working method adapted to their needs! I also offer crash courses for those preparing for the start of the school year, so that they start the year well prepared 💪 and with a head start on the program.🧠 💭 If you have any questions, don't hesitate to contact me ;)
