I just scraped through this exam and just passed. Thought I had it all covered well after using the practice exams from AFT and scoring very well in it. But the CASA exam questions were something shocking. No questions about past accidents and incidents related to poor CRM, nothing about glass and modern cockpit design (it's ATPL afterall) and the questions were written to deliberately trick you and not test on your knowledge and understanding. I actually enjoyed the course material (used the ones from AFT) and found it interesting and actually learnt alot for the sake of my own health with flying but CASA's exam questioning leaves a lot to be desired.
