It very much depends on the examiner. The form mentioned above is the topics they can ask you about- for my students (not for atpls, but for other flight tests ) I used to recommend putting s document together with about a page worth of information (or as much as you can put together) for each topic. Keep it practical as you can but cover the theory aswell.
For example:
Flight and duty limitations - what do the regs say, how much leway do you have with the limitations, "crewing calls and asks you to do x, can you do it"
