@Swimming: the more MCQ you do, the better the chance of stuff sticking. You will always have ‘ahh, that's what I should have done' moments when you do MCQ and believe me I have gone over FAR stuff many times enough to know that the key is to attempt as many MCQ as you possibly can.
When I started, I did MCQ and looked at my notes to get clues when I couldn't answer without notes (of course sometimes I still failed the MCQ even with my notes in front of me). When you go over and over and over again, you will start to rely less and less on your notes. That's the point where you'll realize stuff had been sticking all along without you ‘knowing'. 🙂
I started off just like you, in 2010, wondering if I would ever know enough to have a chance at passing. After passing 3 partsI gave up because I was too scared of FAR to try to understand it. But in April 2015 I started again and I am at the point where I know that with enough MCQ and practice, I can do it. So, just keep on, you will get it eventually, but it will take hundreds of MCQ.
Also, if it's any encouragement, sometimes you don't know stuff has been sticking but you get to the exam, see a question, and then you remember what you had studied about it.
Good luck! Don't drown like I did in 2010! 🙂
