CISA passed first try with a 488 — here's how I structured 14 weeks of prep
Just got my results back and I'm still a bit in shock — 488 out of 800 on the CISA, which clears the passing threshold of 450. I've been in IT audit for about 4 years but had always put this exam off because the reputation for difficulty felt daunting. Finally committed in January and sat in mid-April.
My study structure was 14 weeks total. First 10 weeks I went domain by domain using the official ISACA review manual, spending roughly 10-12 hours per week. Weeks 11 and 12 I shifted to a third-party question bank and drilled about 50 questions a day, reviewing every wrong answer in detail. Weeks 13 and 14 were full practice exams under timed conditions. I was consistently scoring 68-72% on practice exams going in, which aligned pretty closely with my actual result.
Domain 1 and Domain 5 were my stronger areas coming in. Domain 2, Governance and Management of IT, took the most work — the COBIT framework questions are nuanced and the exam doesn't test it the way most study guides present it. I'd allocate extra time there if you're planning to sit.
One thing that surprised me: the exam isn't as purely technical as I expected. A lot of questions are scenario-based and test auditor judgment more than knowledge recall. If you've done real audit work, lean on that instinct — it's actually useful here, unlike some certifications where experience almost works against you.
I sat for CISA after 6 years of audit experience and still needed every bit of 12 weeks of prep. Experience helps you reason through scenarios but the terminology and framework specifics still have to be learned deliberately. Don't skip the manual.
Congrats! That score on a first attempt with 14 weeks of prep is solid. The governance domain tripped me up too — I kept trying to apply real-world audit logic and the ISACA framing is sometimes subtly different from what you'd actually do on the job.
The 50 questions a day review approach in weeks 11-12 is exactly what I did and I think it's the most efficient way to surface weak spots. Passive re-reading doesn't reveal gaps the way working through wrong answers does.
Domain 2 with COBIT is where a lot of people leave points on the table. The key thing I learned is that ISACA wants you to think in terms of controls and governance principles first, operational reality second. Takes mental adjustment if you're used to hands-on work.
Honestly I almost quit twice. Around week 6 I was convinced I'd wasted my money because the practice scores weren't moving and the domain 5 stuff just wasn't sticking. What turned it around for me was finally accepting that this exam isn't testing whether you can do the job, it's testing whether you think like ISACA wants you to think. Once I stopped answering questions based on my actual 4 years of audit experience and started picking the "best" answer their way, things clicked. If you're sitting there feeling like you don't get it, you might just be overthinking it the way I was.
The 14 week plan helped but I'll be real, I didn't follow it perfectly. Some weeks I barely touched it. What mattered was the last month where I did question banks every single day and actually read the explanations for the ones I got right, not just the wrong ones. That's the part everyone skips. Don't. And if your scored practice runs are landing in the low 70s percent range you're probably more ready than your nerves are telling you. I felt nowhere near ready and still cleared it with room to spare.
Congrats on the 488! The thing that honestly moved the needle for me was stopping trying to memorize everything and starting to think like an auditor instead. ISACA writes the questions to test judgment, not recall, so once I started asking myself "what would the audit manager recommend here" rather than "what did the manual say," the answer choices started making a lot more sense.
Also, don't underestimate the value of doing practice questions under timed pressure, even if your scores aren't great at first. I bombed my first few mock exams pretty badly and it was demoralizing, but the explanations for the wrong answers were where I actually learned the material. By week 10 or so it started clicking. Four years of IT audit background definitely helps, but it's not a substitute for learning ISACA's specific way of thinking.
Honestly, I almost bailed around week 8. The practice scores weren't moving and I'd convinced myself I just wasn't cut out for this level of exam. Kept second-guessing every domain, especially Information Asset Security and Control -- felt like no matter how many times I reviewed it, nothing was sticking. What kept me going was weirdly small stuff: I told one coworker I was sitting for it, so quitting felt embarrassing. That tiny bit of accountability was more effective than any study plan.
Congrats on the 488, that's a real score on a real hard exam. For anyone lurking who's at the "should I even bother" stage -- you probably feel way less ready than you actually are. The test isn't punishing you for what you don't know, it's rewarding the thinking patterns you've built over years of audit work. Trust that more than your practice test percentages.
Thanks for the detailed breakdown — this is exactly what I needed to see right now. I'm about 5 weeks in and just hit 74% on my last practice run, which felt good but I'm not sure if I'm drilling the right stuff yet. Spent a lot of time this past week on cisa/questions/it audit standards and frameworks 2 because frameworks kept tripping me up. It's starting to click.
Planning to sit in late September so I've got roughly 10 weeks left. Honestly I didn't expect to feel this confident at this stage but the daily practice is doing something. Did you find the real exam leaned heavier on one domain over others? Trying to decide where to double down these next few weeks.
