CISA Review QAE Manual 2014 Supplement Paperback – November 15, 2013

I took the exam in December 2014, and I can honestly say that if you use this and understand the questions then you will be fine. Is it necessary. I would say no if you have purchased their exam review questions bank. But if you haven't and do not intend to purchase their questions bank than I would highly suggest you at least obtain this and understand this inside out.
