I'm glad I wasn't the only one who had an issue with that question then G-EMMA! Next time I'm stuck with the confuser I'll send you a PM!
The volume of study is definitely tough to fit in among work, family commitments etc. I find that it helps to set a realistic target date for each exam and then commit to doing it on that date to your instructor/family etc. That way there is enough pressure on you to make you want to do the work, but if the date arrives and you are really not ready then you can still postpone.
I agree with G-EMMA's point of view that the exam questions are very much suited towards people who are good at 'learning the question'. I tend to have a go at the confuser questions within the day or so prior to the exam. This gets good results (not quite as good as G-EMMA's though!) but I'm concious that it doesn't help me remember things in the long term. As such I try to do plenty of study and note-taking from the books and CD-ROMs before even looking at the confuser.
