@blankk: No, I don't think so. I leafed through a few pages and frankly, at that high of level where you're aiming for the high scores (like I was), books will tell you little more than what you already know instinctively. When you're heading for the 2400, your goal is NOT to make dumb mistakes, not to use tips to boost your score. If you want that 2400, you should be testing/retesting/correcting answers regularly. Gotta be on your A-game to get that 2400 single sitting.
