I offer online tutoring in Mathematics and Physics both for the IB but also for other systems. I usually carry out my lessons on Google Meet, where I connect my iPad and where I can carry out the exercises with the students. Students usually tell me in advance the topics to be covered in the following lesson, so that I can better prepare the material. At the end of the lesson, depending on the student's needs, I can also leave "homework" exercises to be carried out as additional practice.
