While there are a lot of options questions on the exam (at least there was in mine), I found the options questions some of the easiest ones of all. If you're having trouble, yeah, skip through the rest of the stuff and then come back to options at the end. As others have said, draw the diagram. If you understand the name of the position, it's almost impossible to fuck it up if you draw the diagram. Don't ignore currency options either (it only takes an extra 10-20 minutes, so why not). I ignored them, thinking who the fuck needs to know that shit, and I got two questions on them. One I, luckily, knew, but the other one was so twisted I think they just put it there on purpose to piss you off (like even if I studied no way would I have got that one).
The best way to study, I think, is just do heaps and heaps of practise questions. I don't think it's really all that hard to get 70% (is it still that to pass?). If your exam is anything like mine and other people I have talked to, about 3-5% of the questions on there you're just not gonna have any clue about whatsoever, so don't get discouraged when they happen to you. I got virtually all of my 'evil' questions in the first part, and I was stressing bad, but the second part went way smoother. Ended up with 85%.
