The QAE has been a very useful book, indeed. Lots of curve balls in its answers. The Review Manual was comparatively skimpy and unsatisfying. Did you take ISACA classes, or did you take a specific boot camp?
For the CISA I took a class organized by my ISACA chapter.
For the other 3, I took classes organized by the NY Metro chapter, given by Jay Ranade.
Both classes were given by ISACA-approved instructors, tho these aren't the classes they offer thru their website.
