Hello, I am a first year Mathematics and Philosophy student at King's College London. I spent almost three years tutoring 4 different teenagers in subjects like mathematics and physics. The outcome was really positive as they all managed to pass successfully these subjects and one of them also managed to improve his average mark in physics from 50% to 70%. Generally, during the lessons I start by checking the Homework that the students are supposed to do and work them out together. In case of lack of understanding, I try to go back and reinforce their knowledge of the theory so that it is possible to me to explain how the exercises must be done. Once we reached this point, we try to do a reasonable amount of them in order to strengthen the understanding in the pattern of reasoning.
