Problems On CFA Website Are Really Hard

Anyone else finding the practice problems by section (not the mock exam) to be worded to trick you? I feel like these problems are harder than the mock exams.

Like n-day VAR=sqrt[(250/n)]. Is that in the book?

Sorry it is anualized VAR=(n-day VAR)*sqrt(250/n).

Sorry it is anualized VAR=(n-day VAR)*sqrt(250/n).

I think the same questions are asked in CFA PM mocks ?

the exam is worded to try to trick you yes. be thankful to have practice trick questions.

either that or those are not really trick questions at all, and you’re just behind
