Chemistry section and content order

I find that the chemistry course should have the video ordering revised. Or at least there should be a guide on what videos to watch in order if you are learning from scratch. I feel like it is organized by topic in a way that it goes from very basic to somewhat advanced in a particular topic, then you move to another topic and goes from basic to more advanced.

But the thing is that some concepts that are presented in these different sequences of learning are required in videos that come before. For example, chemical bonds that are presented much later but are required in earlier sections.

Maybe the sequence of learning should be presented in a more parallel and even approach with the different content sections.
