I did. I took it in December.
You would have enough time if, and this is a big if, you commit yourself, meaning studying for 2 or 3 hours every weekday, and more than that on Saturday and Sunday. Trust me, I’m not exaggerating, you need a lot of time to prepare for this, especially if your academic background is not finance-related.
I studied with the official books the Institute provides. The Kaplan Schweser books are a condensed version of it, some people say they’re essential, I think they’re helpful but not indispensable. What you really should get are sample tests: practice is key.
Overall I spent close to 200 hours studying, counting three full practice tests. Results will be released next Tuesday, I’ll let you know if my method was successful.
