These are two threads which tell you everything about preparing for L3.. I would like to add my couple of points from my experience as well (as you can see from my status, I have still not passed the exams - so you are free to take that or ignore it completely)..
1. Take hell a lot of practise exams especially the essay part. Multiple reasons for that actually,
a. If you dont have the habit of writing, gets you that habit back. Much needed for the exam because you need to improve your speed..
b. Use intuitive shortforms where you can. Remember the guys who correct are charter holders as well and they know (probably) better than you & me. I strangely practised that at my personal exams, but on the original exam I was unnecessarily more verbose than I should have been.
c. Makes you think and sometimes you can get stuck in a simple word and you dont know what other word to use in place of the same

Not sure if it happens to everyone, but I was struggling for the word “strategy” in one of the personal mock exam papers

) The more you write the better it works..
2. Do not ignore the PM exam totally. Take sufficient practise there as well. Remember there have been instances in the past were people got screwed in AM and passed the exam based on their superior PM scores.
3. Do not game the exam. Lot of the topics would appear too easy, but CFAI can surprise you very well here. They did it to me and lot of other folks in 2013

Nothing is more important, nothing is less important. Remember you can get essay questions on these topics and if you dont know specific terms you are in for a shock as you just wont be able to answer… 2012 AM has a couple of questions and you would understand if you look at that paper.
4. After finishing each Reading or Study Session, see if you can write down top 10 things you learnt in the session.. This was suggested to me by a friend and this helps you get a bigger picture and sometimes helps you connect one Study Session to Another.. And in L3, its very very important to have the bigger picture.
Good luck and pls wish us well for the results as well
