Are All LOS Created Equal

I am wondering if the mock exams provide an indication of which LOS are most likely to be tested. I know they are all supposed to be fair game, however, based on the Mock exam, it looks like the following were really stressed;

5.20c Lifo-fifo conversion

6.22a investments in associates, etc (big time)

7.27c,d,e impact on ratios and fs

any other observations?
