I took this course while I was at the intermediate level of Python. So to save time, I skipped most of the lectures and studied only with the PDF provided. I understood it very well just by reading the PDF. It must not have been easy to make it easy to understand just by looking at the lecture materials, but you are amazing. Since you provide such a high-quality lecture for free, I want to buy the next paid lecture even more. I will leave this review and go buy Java Basic!
