Ah, the way the lecture keeps switching to other things or inserting random bits in the middle makes it even harder to understand. It would be fine if they just stuck to explaining one thing at a time, but the constant shifting of content is really stressful. I mean, the organized files could just be explained after the lecture is over; showing the file first and saying "I'll explain this later" is really annoying. Nothing is organized in a way that matches the pace of the lecture. From a viewer's perspective, I don't understand why I have to be the one piecing everything together to make sense of it.
