Whats up Raz. I did world twice. It took me about a month to do WORLD and then I redid 1400 questions the last week before the exam... I only read the educational objective the second run through which is why I was able to get through 1400. Personally, I really think this was key.....I learn best through repetition. I think as long as you remember the concept behind the question, it doesn't really matter whether or not you remembered the answer. Plus, you score significantly higher the second time around.... some will argue that this gives a false boost of confidence but its confidence no less. I haven't received my score yet so take what you want from this. I can say that even though I didn't walk out of the exam feeling like I killed it, I did feel comfortable and familiar with 80-85% of the questions. Hope this helps
