I understand you are excited, but may I offer advice I saw when I had taken L2, thought I passed (I did!), and started poking around on the L3 board.
First, wait until you get your results. You may be sure you passed, but it’s possible you didn’t. Google Dunning-Kruger, which is touched upon on L3. Also, as another poster said, the CFAI can be tricky.
Second: Even when you do pass, it may not be the best time to jump on the L3 boards and start asking everybody what they should do. We don’t get results until a few weeks after you do and nerves and anxiety will be at an apex then. The best example I can think of is an underclassman asking a senior how to survive his last year when he doesn’t even know if he’s passed.
Third: Take a month or two off. I know it sounds like a badge of honor to start studying for the L3 the day you hear you’ve passed the L2, but that’s more than enough time to prepare for L3. Matter of fact, I’d say the biggest problem I had for L3 wasn’t time to study, it was retaining facts. Starting too early can be as bad as studying too late unless you have an eidetic memory.
But if you want to ignore my advice above, here’s what I’d do:
If you *have* to study, I’d recommend you spend more time on Ethics for a few reasons. First, you already have the material. It doesn’t change from L1 to L3. Spending more time learning Ethics will cost you no money. The only additional piece of information you have to learn for L3 is the Asset Manger Code of Conduct. Additionally, if you didn’t pass, this information is applicable for L2 as well. Ethics is shockingly tricky, and from what I’ve seen it tends to be one of the subjects that seperates Band 10 failures from passers.
Next: GIPS. GIPS tends to get overlooked, and is mostly a set of rules. Most CFA takers tend to overlook GIPS (because the material is dry and awful), you could establish some “test alpha” by learning it. It’s only 5%-10% of the test, but it should cost you nothing. Here’s the GIPS manual, the first 50 pages are what’s going to be tested.
If you HAVE TO just learn everything, these notes are a little old, but good. Maybe non-calculation material like Behaviorial Finance so far out.
Hope that helps
