Success Story Passed CISSP at Q100 (non-native English speaker) - what worked and what I'd change
Background
17 years in IT, with ISC2 CC and Security+ already behind me. I'm Spanish and took the exam in English. Screen went black at 100, and I passed. Here's what I learned.
Study routine (3-4 months)
I studied every single day: some days 4 solid hours, others just 1, squeezing questions into my commute, bathroom breaks 🙈 and gym time.
Pick your sources early and stick with them.
Don't keep jumping between resources. If you need to invest some time upfront choosing your materials, do it: it's time well spent. Once you've decided, commit and don't fall into the trap of constantly adding new sources. Dispersion costs you more than any gap in a single book or course ever will.
My final set of resources
Destination Certification (DestCert): Very good. Their book is a must-have. I also highly recommend their YouTube Mind Maps. I played the audios on a loop for semi passive listening while working out, driving, cleaning... 🥲
Pete Zerger (Exam Cram): Straight to the point for review.
Andrew Ramdayal (Udemy): I used his course mainly for the Networking domain, but his "Manager Mindset" videos were also incredibly helpful to get into the right headspace.
LearnZapp: I did almost 2000 questions and was scoring 80%+ by the end. Great question bank, but two caveats. First, it sometimes uses slightly different terms or synonyms than DestCert, which tripped me up as a non-native speaker. Second, the explanations are very brief.
My workaround, which I highly recommend: screenshot every mistake or lucky guess and feed it to an AI for the detailed breakdown the app lacks.
My biggest mistake
I ran out of time to properly review all my saved and incorrect Learnzapp questions, so I went into the exam with some blurry concepts. If I did it again, I'd reserve the last 2 weeks exclusively for reviewing my mistakes.
The Q100 barrier and time management
The exam stopped at 100, which was a lifesaver: I only had 52 minutes left. If it had gone to 150, I would have struggled badly with the clock. Without realizing it, as I approached Q100 I started taking much more care with my answers, praying it would end right there.
The language factor (non-native)
I took it in English (like my CC and Security+) because reliable translated materials are scarce.
I expected convoluted, tricky paragraphs, but almost everything made logical sense. The trick: don't just hunt for MOST, LEAST or PRIMARY. Pay close attention to small adjectives like "new", "old" or "current". A single contextual detail can change the whole answer.
The "Manager Mindset" debate
I've seen posts dismissing the "think like a manager" advice as an outdated fad. In my experience it's essential.
You need a solid technical baseline, but a big chunk of the exam is managerial, and adopting that mindset to protect the business is vital.
Happy with the result and the knowledge gained. I expected a harder exam.
You can do it too. Good luck to everyone still studying!
