I finished listening to Series 1 and am studying Series 2. The best part is that you explain every little detail so I can grasp the concepts accurately, which is really great. If you look at the class materials, there are diagrams that show you the concepts, which are really helpful for understanding the concepts. I think this will be a really good lecture for those who want to study on their own. I can feel that you put a lot of effort into making this lecture, so I feel like I can't give it 5 stars, so I'm leaving a sincere review :) Can you make a probability and statistics course with the same quality in the future? I hope the integral series comes out soon..! Please do it. I'll definitely listen to it!
