My first ISC2 CC exam attempt ended at question 90. On the retake, it ran the full 125 — and I passed. Here's what I did differently, and what's next.

The first time I sat the ISC2 CC, I was writing into a fog — a first attempt at a machine I hadn't touched yet. This time is different. I've been inside the exam, I know the terrain, and the prep this round was targeted at the specific gaps. Here's where my head is the day before Round 2 — grounded readiness, not anxious anticipation. 💜

On the ISC2 CC, the scenario questions are a different animal from the knowledge questions — and they're where a lot of people freeze. "What should you do FIRST?" isn't testing what you know; it's testing how you choose. Here's how I'm studying them differently: ISC2's Least/Most/Best framework, reading the call word before the options, and budgeting judgment practice separately from recall. 💜

On June 20, 2026, my ISC2 CC exam session ended at 90 questions — with time still on the clock and no error message. ISC²'s own CAT documentation puts the minimum at 100 items. I'm a data analyst, so I did what I do when something terminates outside its expected parameters: I went looking for the data. Here's what turned out to be noise, and the one thing that didn't.

Two certs on my entry-level path — one I've gone deep on, one I've previewed hands-on. This is the honest version: what the material revealed, and where it exposed gaps I didn't know I had.

I failed. Except I didn't. When my ISC2 CC exam stopped at 90 questions, the system gave me bogus results. I could have accepted it. Instead, I found the truth. Now I'm going back in on August 15th to prove it.

The domain I was most afraid of — Network Security — was the one I passed. The ones I felt confident in came back below proficiency. Here's what that taught me about how the ISC2 CC actually tests you.

Two days until the CC exam. The temptation? YouTube at 2x speed and memorizing port numbers I've been avoiding for weeks. But I've done that dance before — for my thesis, with cold chai tea at 2 AM. This time? I'm doing the opposite. Here's the plan, the protocol, and what I'm eating after.

Not another study guide. Just what a data professional wishes she knew about the five ISC2 CC domains before studying.
