Active Portfolio Mgt in CFA curriculum -- formulas need to memorise?

I am not sure any of you have read the Reading #71 of the curriculum. I notice that on page 467 there is a note saying that the forumal from section 4 to 6 are not to be memorized. But if you have done the Practice problems in page 489 you will notice that the formulas have been used extensively. Even the formular nv seen before such as *utility loss* in question 2B. I was quite headach even when I was reading the answeres. I just worry if the institute will test these formulas in the exam day. Any comments?

Anybody has done the Question in the reading?

dddolphin…I don’t think the questions were designed with the LOSs in mind.

That question really makes me haywire…
