A meaningful part of what I found useful was that I knew ~<10% of the content. It was 8 hours effort (Tuesday+Thursday 1 hour lunchtimes for four weeks, including all videos, quiz's, note taking (on the phone I was watching it on), and tests), and I'm now sure I know how to study effectively.

I think one working day is worth it to make sure you're up to date.

I also found the working memory, and memory information in general very informative and helpful.
