Yesterday, I took the CISA exam and the preliminary result indicated that I passed!
It was my first time taking an ISACA exam and my current job has me doing more audit work than I have done in the past so I wanted to get the certification. My work paid for an ISACA membership as well as the CISA question and answer database from ISACA's website.
I purchased it around April but did not start really hammering away on the questions until late July. My strategy (as my coworkers recommended) were to do all the questions that I had not seen yet first, then go back to the questions that I answered incorrectly. I was down to around 100 questions that I was not answering correctly and was consistently getting 60s on the quizzes. Was starting to get frustrated and a bit concerned as I was struggling on those last 100 questions.
A couple of days before my test, I did the practice exams which I got a 66 and a 75 respectively. Yesterday, took the actual exam and passed.
I only used ISACA's QAE database. My experience at work plus experience taking other certifications, specifically the CISSP, helped in eliminating 2 out of the 4 questions then making my best guess on the final 2.
Work will probably want me going for CISM next year. May try to do CCSP to round off the year
