I’ve had this discussion with a friend of mine who is a CPA. He said depending on your educational background, it may take 300-500 hours of studying in total to pass the four sections of the CPA. This seems to line up with what prep providers recommend online.
In comparison, it should take about 300 hours for Level 1 and 200-300 for Level 2 and 3, again depending on education and work experience.
So in total, CFA should significantly outweigh CPA.
