I was reviewing the mock, TT, and I believe I saw it in Schweser mocks too where the vignettes only asked questions about a specific reading. For example in the CFA mock all of portfolio management in PM was about reading 49. Is this what we should expect on the exam or will each topic be likely comprised of questions from all readings? I just found it odd that they skipped so many readings and kept asking different questions from the same 1 reading.
I think the answer is that they can do whatever they want within the %age guidelines they gave us.
There can be one AI topic test with 6 questions on commodity roll yield or two AI topic tests with 3 questions per reading.
We just have to be prepared for anything.
