Gday CJ,
Most certainly, some main ones that spring to mind immediately are;
PEC of -20 was given in a question that is flown as a VOR approach, (of course PEC does not directly affect this kind of approach), so it will mislead you.
Tracking into a gps approach (a reminder there are sector entries for GPS approaches, so take a look at which one best suits
LSALT when tracking outside 50nm and being 20 degrees off course from an ndb (most poorly worded one)
asking LSALT Boundaries with/Without 5nm buffer
Underlined altitudes after a reversal turn to turn onto final track (have a good look at what this means)
clouds over mountains and there related shape and turbulence
fuel requiring emergency was very poorly prescribed, just remember, priority approach generally is the incorrect response, they are more or less looking for MAYDAY
sometimes the question will specify an ERC low, but, wou are much better off looking at TAC (how far from dme will you hit this airspace)
YSSY and YBBN have traffic holding time prescribed in ERSA, have a good hard long look in notes
Departing IMC with engine failure after takeoff and continuing to destination (i believe MSA but dont quote me on it)
Edit: In an ils procedure, remember, it is a degree rather than percentage, thus check the front of daps for degree rather than %)
That is most of what i can think of, just remember, i didnt sleep before the exam, and am naturally fairly braindead, BUT,
I can happily say i PUT THE WORK IN, and familiarised myself with as many questions as i could to under stand the tricks casa does, and my result always makes me happy of that fact, dont stress, if i can do it, anyone can!
The burden of the exam no longer bothering you will be worth it all when you are punching through cloud!
Best of luck and let me know how you go!
Regards,
Stephen
