I teach in online mode using the meeting platform that the student is familiar with and feels comfortable with. For grades 9 and 10, I provide power point presentations to students and teach the concepts with its help. To help students with numerical and for higher grades, the pen-paper method is the best used. Sometimes in order to teach a concept better, I provide supplementary material, like links on the internet or supplementary notes. Class timings are set as per the convenience of both the student and the teacher.
