advanced video lessons?


I don't know know if this should be asked in site feedback.
but how does the videos get the category advanced.

I have just seen a video that was rated advanced but I think I understood it.
should I skip videos that are advanced and only focus on beginner/ intermediate videos? what is guideline how to use the videos.

I know I can watch all videos but will advanced videos overload me with information that I am not ready for?
