If you've: (a) studied a reasonable amount, and (b) have a modicum of finance and accounting knowledge, then the only thing you really need to deal with is exam strategy. It is very fatiguing going through 6 hours of those questions in one day under real exam conditions. Wait until you get to around 4pm on test day and you'll see what I mean. The Level I material is not difficult, there's just a lot of it. If there's a complicated formula, they are not going to ask you a question on it. Don't waste too much time studying derivatives. (I'd say the same for fixed income, but you'll be glad you learned the basics in that area once you hit LII and LIII.) Forget it and know your accounting ratios inside out, as well as the dupont ROE formula and that should get you about 30% of the exam in the bag. Do as many practice ethics questions as possible and you should be fine.
