I just bought the Schweser Level III QBank yesterday for $299.99 and started working my way through it just to get some immediate feedback on areas that I need to review and focus on more. The questions are certainly not as challenging as the CFAI cirriculum, but they seem to give me a decent guage on which sections of the CFAI text I need to go back and review. Again, I’m not sure if the value-to-cost ratio is there or not with the QBank, but it seems to be decent for purposes of obtaining immediate feedback on specific areas of the cirriculum. I just wish the cost of the QBank was much less since I don’t plan on using it as my primary tool for review purposes.
