not strange at all
by focusing more on some important chapters and lesser care to those not so important chapters
examiner can easily catch all students off guard if he really want to fail you all
i myself had tried this b4 ... not focusing on linear progression on f5 since it came out last sitting
oso did not revise on ABC as it was asked as well
when i flip the question booklet and saw both ABC and linear progression...I was stunned
however, "luck" did side me as I managed to get 51 ...so close to fail
thats why I emphasis on better not knowing the tips and rather revise all
and the luck I mentioned..apart from "preparation meets luck" from another forumer ...
it's the luck u got the questions u liked, have confident... rather than the questions spotted by lecturers but you're not really good with it... or u're not good with it but u have some luck to get 50% of the total marks
when u noe tips...u will tend to focus more and lost some care for others no matter how u argue
im not trying to stand on high ground and menegur u all
i was rushing for time so i leave short reply... if not i will type long posts

Added on May 18, 2012, 7:00 pmp/s: by revising all ... u can at least get 50% from all questions eventually (theoretically) rather than hoping to get 50% from those important chapters alone
But the truth is, acca syllabus is really huge. To study every chapter and continuously pay attention takes really serious dedication.
I'm not even sure if there's enough time now to revise all the chapters and manage to retain everything for the exam. Thats why ask for tips for important chapters. Haiz...sucks to be an acca student T.T
