CFP is not easy mzwerner. Nuff said. You have to memorize tax code, estate planning techniques, corporate retirement plans, etc. You might think that you know this material, however you are humbled once you have to start memorizing all the crap. Do you have the CFP mz? I would be surprised if you did as I suspect you might have a different opinion. Trust me, having to memorize corporate benefits is not easy and you will never use it later in your career. I would argue that the CFP covers too much material for the designation as you will not need 90% of the material after you pass. However, that is true with most tests. It takes a good 12-18 months to memorize and pass the test.
CIMA (Certified Investment Management Analyst) is the easiest one to obtain however it is barely recoginized and it is super expensive. You have to spend 2 weeks at Wharton or Cal-Berkeley as pre-req to passing the exams. You do get to learn from their professors (and pay them!!) which is a nice bonus although you forget all of it after you take the exam anyways. You can obtain this in a month.
