The CFA exams are much harder than the CPA exams. The CPA exam has four parts: Audit & Attestation, Financial Accounting, Regulation(Tax), and Business environment and concepts. I think the Financial Accounting section of the CPA is harder than the FRA section of Level II, but overall Level II is a much tougher exam than any part of the CPA exam. I think the CPA test is similar to the CFA in that they are both very detailed and take a lot of time to prepare for, but are different in that the CPA concentrates more on how to perform detailed transactions (ie, journal entries, putting together B/S, I/S etc.) and the CFA concentrates more on how those entries affect the financial statements as a whole. I think the FRA sections of the CFA will help you with the Financial portion on the CPA exam , but you will still have to spend a decent amount of time reviewing the detailed accounting information for the CPA. Just my opinion.
