Level 1 is offered twice a year (June and December), Levels 2 & 3 are offered once a year in June. i have two professors who passed level 2 and 3. In order to get your charter you must have 3 years of relevant work experience (so you should get that while taking the exams). Also to actually get the charter, you need a CFA member to sponsor you. By then you should have joined the Institute as an affiliate member and gotten to know people and attend some local society events.
I am signed up for December and have only put in 100 hours of studying. I have a friend who passed level one this summer right after graduation, he studied a lot and was very academically gifted already. No one should kid themselves, this is not a fun exam.
I have also heard the same, most people who pass level one get destroyed on level 2 because of a confidence and therefore reason not to study as much. Level three is a lot of writing. i know investopedia.com has a good breakdown of what each exam consists of. From what I know, most finance majors take the exam but level one has a large focus on Financial Statements, something you can only get from taking intermediate accounting 1 & 2. Many Finance programs do not require these classes putting students at a disadvantage. If you get this down, you have 1/4 of the exam beat. Good luck to any one who signs up. They say the recommended amount of study time for level 1 is 250+ hours.
