    I have watched so many videos on this topic, but you have the most to-the-point, precise explanation I’ve ever watched. You explain things as it is and never have I ever seen you advertise for your tutoring business. Nothing is wrong with that, but to me it just shows your genuine and passion in teaching. Know that your work has built a community and it continues helping a large amount of students!
