None of the PF posts are particularly helpful. More about chest beating than anything..
I was exactly the same in the Irex exam. I used the Bob Tait book and dutifully read each line of the text, smiling more and more as my understanding of the topic grew. Then I’d get to the sample questions and low and behold would get stuck at the first one! I’d assume Bob had “made a mistake”
and I would be the first to tell him… then of course after re-reading the SAME section four or five times, turns out Bob was right after all!! (shock, horror)
Then I'd move onto the second question…..
Point is it took me a good while to get the info into my head. Never had a problem with the other topics, just that one.
Happens to us all…..
