I don't want to tell you how many hours I studied or how many practice questions I did.
And everyone here has already heard it: Know your domains. Take practice tests. Think like a manager. Yep, we all know that. But CISSP isn't just about that. It also tests your mental stamina, your psychology, and your ability to survive weirdly worded questions.
The point is, CISSP isn't about memorizing facts. It's about keeping your cool when everything feels uncertain and making decisions even when there's no obvious right answer. Success isn't measured by what you know, it’s measured by how you handle confusion, racing clocks, and second‑guessing yourself.
Here's the dirty secret. There will be questions that make no sense. Questions where every option looks right… or wrong. You will doubt every choice you make.
If you go in expecting an engineering test, expecting a clear right answer, or thinking manager mindset only, you will 100% fail CISSP. The exam pulls from every angle and forces you to make decisions, because real security isn't black and white.
Train yourself to read questions twice before choosing an answer, eliminate obviously wrong options, don't chase the perfect one, and get comfortable with being uncomfortable.
Resources, my favorite theme. Stick to the basics and add something extra from the long list of recommendations in the sub. I used ISC2 CISSP test prep. Period.
Any thoughts?
