I feel far too many books make assumptions that things are "common knowledge". I think they are afraid of putting too much remedial and review stuff at the beginning or in the book in general. But in reality, the percentage of people who understand something fully at the 'expert' level is very small. Best way to find out if you know something or not is too teach someone else.

This is exactly on point, for any kind of teaching. And reviewing the 'basics' can help situation information in context you already know. Ironically, I often use a paging metaphor here, for stuff that I learned, but haven't thought about recently... going over something again to refresh my memory is just swapping that page back in.
