Keith, thanks for posting the questions. Personally I have found those questions, very similar to the ones I have already worked through, in fact, a few are exactly word for word. I am finding that the more times I work through my feedback, my knowledge and understanding is increasing. 2 or 3 weeks ago, I would not have stood a chance in answering the questions above. However now I am able to go through them, and similar questions with few problems.
Thanks for your help.
Good luck to eveyone sitting exams.
