exam format

I have seen that a lot of the mock exams (from 3rd party providers) break the exam down into specific topic areas. My question is, is this the same format and structure of the actual CFA Level 1 and Level 2 exam? I.e., can we expect something like “Questions 15 – 35 relate to FRA” etc? Or should we expect all the questions to be shuffled around so that (for example) question 1 is FRA, question 2 Fixed Income, question 3 Derivatives etc etc…. Cheers…. JM
