I usually like to start by testing the student's level in physics. Afterwords, we can begin by explaining the most important concepts that the student fails to grasp. Then, I like to work on as many problems as possible so that the student incounters all the possible types of problems. We classify these problems and then begin to focus on the problems that the student always fails to answer. I like to also test how fast a student can answer a problem by timing him which is a great way to prepare for examinations. I always encourage students to ask as many questions as they can so I can clarify all the missing points. I also try keep track of the student's performance between each and every session so that he can see his improvement and if he doesn't I am always willing to provide more time and effort to get the best out of my sessions.
