Math support courses for high school students (Science Maths, Science Exp, Letters ...)As a teaching professional, I have always enjoyed sharing my knowledge. My goal is to provide quality education. I am aware that some topics may seem complex, but often this is simply the result of an inadequate explanation by the teacher. With me, you will discover a real interest in the material!
We strive together to achieve academic excellence, overcoming the shortcomings and difficulties encountered by your child. Studies will become a pleasant experience for him. In addition to the courses, I can also help with school orientation, identifying their preferences and highlighting the advantages and benefits of a fulfilling educational ambition.
The sessions generally take place according to the following stages:
1️⃣ The first sessions are devoted to the assessment of the student's level in order to detect existing gaps.
2️⃣ Next, we create a personalized plan to address these gaps, including the number of hours of work needed, specific areas to focus on, and appropriate training and development exercises.
3️⃣ We stay in constant contact with the student's class teacher, to keep up to date with the latest requirements and ensure a consistent approach.
4️⃣ Subsequently, I provide exams similar to those that are likely to be asked in class, to prepare the student effectively.
5️⃣ Upon request, I write a regular report, usually monthly, to keep parents informed of their child's progress throughout their course.
I adapt my methodology according to the specific needs of each student, thus offering them a personalized and adapted work approach.
In addition, I offer crash courses for students preparing for the start of the school year, allowing them to start the year well prepared, with a solid lead on the school curriculum.
If you have any questions, do not hesitate to contact me. I will be happy to help you.
