Are you a middle or high school student and are you having difficulties in Maths or Physics-Chemistry? Or do you want to improve your course and/or your methods for solving exercises? Don't let yourself get overwhelmed by letting your gaps accumulate. In my journey to a master's degree in theoretical physics, via an engineering school and a scientific preparatory course, I was able to help my loved ones and my students in their studies, which allowed me to develop learning and exercise-solving methods that I would like to pass on to you. I offer you an initial assessment of your situation to evaluate your objectives and the working methods which will enable you to progress, then we can define an educational strategy for the future.
