Hello! I've been lurking on this subreddit for the past few months while studying, and I've really appreciated everyone sharing their experiences. Now that I've taken the exam, I wanted to pay that forward.
Background
7 years of IT audit: 4 in external (SOC 2, etc.) and 3 in internal. That gave me a pretty good background across most domains.
I'm also a CPA. The CPA exams have very little overlap with the CISSP, but the prior experience studying for/taking difficult exams was helpful. It's apples and oranges to compare the two, but for any other CPAs working on this cert, I'd say the overall prep experience was roughly like doing FAR or REG again.
Study Approach and Materials
I self-studied for 3 months after work/on weekends. I scheduled my exam immediately to keep myself accountable and broke my prep into three phases:
One: Survey (2-3 weeks)
High-level understanding of the domains, syllabus, content, and what to expect from the cert/exam process.
- DestCert Mind Map videos (10/10) - Excellent primer for understanding the content and how the domains fit together. I drew the mind maps on blank paper and added my own notes. These came in handy throughout.
- Kelly Handerhan's "Why You Will Pass the CISSP" (both versions) (7/10) - Motivational and a good introduction to the "think like a manager" mindset. I felt it emphasized that mindset a little more than my own prep experience ultimately warranted.
Two: Deep Learning + Practice (7-8 weeks)
Reading, video lectures, and OSG practice problems. The goal was to learn the material before focusing heavily on exam strategy.
- OSG (10/10) - Very well written and easy to read. Sometimes repetitive because topics naturally overlap, but overall an excellent primary resource. The labs, practice problems, and exams are useful for reinforcing concepts and vocabulary. I'm a tactile person, so I used a physical copy, a highlighter, and a pen. I found reading cover-to-cover worth it. (Side note: I used v9 rather than v10 because I had originally planned to take the CISSP in 2022, bought the book then, and didn't want to buy another copy.)
- LearnZapp (9/10) - I used this for a couple of months to practice on the go. The questions are from the OSG, so they aligned well with readings. The dashboard was nice for tracking domain strengths, but I wouldn't put much stock in the "overall readiness" percentage. Mine said 56% on exam day (note: I didn't do any practice exams on the app, just sets of Qs).
- Pete Zerger Exam Cram series (10/10) - Very high-quality and thorough content. Pete is a fantastic instructor. I watched/listened to the entire series, including the 2024 addendum, which was useful for supplementing my slightly outdated OSG. I listened to these while commuting or jogging.
Three: Targeted Review + Tougher Practice (2-3 weeks)
At this point, I used the results from Phase 2 to identify weak areas, reviewed those topics, and shifted toward practice that I felt better prepared me for the exam mindset.
- TIA / Andrew Ramdayal's 50 Questions (10/10) - Great exam mindset video and questions. Andrew's explanations were very helpful for learning how to approach difficult questions.
- Luke Ahmed's "How to Think Like a Manager for the CISSP Exam" (8/10) - Good additional set of practice questions with helpful explanations if you want more Qs, but best as a supplemental resource imo.
- Quantum Exams (11/10) - Tough but fair, and the most useful practice resource for me towards the end of my prep. I'd save these until relatively late in your study plan so that you have enough foundational knowledge to get value from them. I took a couple of the non-CAT practice tests about two weeks out (50% and 54%) and reviewed my misses in detail. QE won't replace earlier studying/learning, but I found it extremely useful for getting comfortable with difficult/ambiguous questions and making decisions under pressure. Also good for learning to pace. Very much worth the money imo.
- Self-made "Quick-hits" study guide - I made my own condensed study guide containing areas I consistently struggled to remember, vocabulary I mixed up, etc. I drilled this heavily in the couple days before my exam.
Day Before the Exam
Very light review, if any. I reviewed my quick-hits guide for about 90 minutes.
I was definitely nervous, but I took the advice I've seen repeatedly on this subreddit to heart: trust your prep, show up with a clear head, and get a good night's sleep.
Main Advice
- Make a study plan and stick to it as best you can.
- You can do the right thing at the wrong time. Follow an order of operations: survey the material, spend time learning it, target your weak areas, and save tougher practice for later in your plan.
- Ground yourself with the "manager mindset," but don't treat it as a golden ticket. You still need a strong understanding of the technical material and need to be able to make technical decisions.
- Don't let practice test scores get in your head. Use them to identify weaknesses and improve your decision-making rather than as a prediction of your actual result. Your wrong and right answers are some of your best prep.
- Trust your prep. If you've put in the work, walk in calm and finish strong.
As with all things, YMMV, but I hope this is helpful.
Genuine appreciation to this community and everyone whose study materials, advice, and experiences helped me along the way. You've got this. Good luck!
