Hello, I am a mathematician. I am giving lectures for university students. For Seven years, I teach Calculus, Linear Algebra and differential courses. Last 3 years, I am giving these courses online. In the first lesson( which is free), I try to understand the needs of the student. After that, we decide together whether we can continue or not. In the case where I realized that I cannot teach, I stop teaching. When we decide to study together, I prepare notes, questions,quizzes for the student. I also help for homeworks.
