Sorry to hear that JamaicanJem. Hope you will have renewed enthusiasm for April. I passed but feel very lucky as the whole m subscript x thing on the last question really threw me ... didn't remember reading about that!
I feel for anyone writing CT4 - i knew the work but the exam threw me a few times!!!!! Just keep pushing it will pay off
Passed on first attempt, so glad I did, I was dreading having to sit it again along with 2 more CTs in April.
