Hi Rinky,
I have been qualified about 17 years and being so long since I had studied I found it really hard. My friend had done the Canadian exam too and thought this one was a picnic compared to that though!!
I found the study connect website really helpful - "apec caop exam' thread. Read from start to finish and you'll know exactly what to expect.
Also I paid for membership of the apecexam.com website which was money well spent for me.
If you're newly qualified then it probably won't phase you though.
It all takes a lot of time and money but all worth it as now have a 189 visa!!
Just need somebody to buy my house and hope to be packing my sunscreen sometime soon.....
