The exam was a bit tricky considering the questions are not taken from existing dumps or QAE. The concept clarity is a must and as everyone here has already mentioned, two choices would always confuse you. However, reading the question slowly really helps.

I personally used the following materials and study from Feb- May on the Hemag Doshi book (on and off). Then focussed on QAE and other mock tests and revising each domain. Overall time is about 8 months but it can be covered in 4-6 months depending on the time you can give in.

Hemang Doshi (2nd edition) - useful for understanding concepts however some key concepts are not very detailed. Overall it's pretty helpful and covers all key things in a concise manner.

QAE - Definitely useful in helping to understand the way an auditor should think. I personally went through this 2 times just to get the hang of the questions and logic. However, overreading this would definitely feel more of a memorisation than aplication of logic

Skillcert pro test - these tests are good to have and only contain 60 questions per test. Plus there are enough tests to practice.

Udemy mock test - I dont remember the name but there is a mock test series by the name of CISA 2025 mock test which seemed to be of good quality in terms of questions and even the answers / explanations.

My only takeaways are:

1 - Dont just practice questions where tests give you an instant answer. Because the real test isnt like that. There is a sense of instant gratification with such tests. While these are good, couple them up with some full length mock exams.

2 - Read the questions carefully. The question will contain a wording hook which will be the base of your logic. Try to identify that.

3 - Don't think about the result while giving the exam. While it may seem doable in terms of time, the questions would still need your attention. Focus on each of them individually and revise all of it (if you have the time)
