Enjoying this liberating feeling :-D
Passed it two weeks ago in first try. 🎉 I learned for around ten days in the evenings after work and one intense 3-day-weekend.
Only used the QAE. And there is plenty of free summarys which can give you a good view on how to apply the "ISACA logic". This was challenging for me in the beginning, as I already worked around 4 years in external IT audit for a Big4 company, and sometimes the prios for ISACA are different than those how you sometimes would do it in the "real world". 😄
However, my advice it to not overthink it. I stressed myself hard after two days thinking i would fail 100%. 😄 However, If you do the QAE, write down the ISACA vocabulary which you didnt understand and get a feeling for the ISACA logic, I'd say it's definitely manageable.
Feel free to ask any questions :)
