 Hi, my name is Wenming Li from China. I have finished one 20 hours on online Tesla trading and I'm very glad to hear that I have completed this course successfully and I learned a lot from this course. And the most impressive part is the lesson plan, which I developed very carefully in the first time, but I didn't pass. Surprisingly, I got the feedback with very detailed suggestions and comments. And then from this part I learned a lot and improved this lesson plan developing skills by following the instructions and feedback. I was really moved and I think this kind of course training are very helpful for the teacher to develop his or her teaching skills and with a lot of practice following the instructions from this course. Thank you very much again, really appreciate for this course. Thank you.
