I just started Book 4 (“Leaves”), and scanned ahead. Once again, no lengthy discourse on some completely non-testable (irrelevant) statistical phenomena. I really count on those sections in order to get through these books. I don’t think I’ve seen one optional reading yet!!!
Swaps, Book 5. It is the only one I have seen so far. I love those sections. I treat them as if they don’t even exist.
You won’t get nothing until you get to the swap section at the of book 4. Which I thinkl that I will have to skip next week. They are liar, there is basically nothing to skip.
I just read Schweser and treat the entire CFAI texts as optional material.
