How to Pass CompTIA CySA+ in 30 Days
TL;DR
- →Don't touch practice exams until Week 2 - use Week 1 to actually learn the material first or your scores will just discourage you.
- →SIEM log analysis and incident response sequencing are the two topics that sink most CySA+ candidates - spend disproportionate time there.
- →Use Jason Dion's Udemy practice exams and treat every wrong answer like a lesson, not just a score to improve.
- →Stop studying the night before the exam - your brain needs rest more than it needs one more chapter, and that's not motivational fluff, it's how memory consolidation works.
Thirty days to pass CompTIA CySA+. Is it doable? Honestly, yes — but not for everyone. If you've already got your Security+ and you're working in security day-to-day, 30 days is tight but realistic. If you're coming in cold with minimal hands-on experience, you're setting yourself up for a bad time and a $404 lesson. Here's the thing — CySA+ isn't a memorization exam. It tests how you think through threat detection, incident response, and vulnerability management. That takes time to wire into your brain. But if you're ready to put in 2-3 hours a day and actually do the work, this plan will get you across that 750 threshold. Let's get into it.
Is 30 Days Realistic for CompTIA CySA+?
For someone with Security+ already under their belt and real security experience - yes, 30 days works. You're not starting from zero. CySA+ is rated intermediate, and CompTIA means that. The exam runs 165 minutes and hits you with scenario-based questions that punish surface-level knowledge. People fail this exam not because they didn't study enough hours, but because they studied the wrong way - reading notes instead of analyzing scenarios. Plan for 60-70 hours of focused study over the month. That's about 2.5 hours a day on weekdays and 4-5 hours each weekend day. Don't think you can cram it into week four. You can't.
Week 1: Build Your Foundation
Start with Mike Chapple and David Seidl's official CySA+ Study Guide - it's the closest thing to a required text. Don't try to read every word. Focus on threat intelligence, vulnerability scanning, and the incident response lifecycle. Those three areas alone represent a huge chunk of what you'll see on exam day. Pair the reading with Professor Messer's free CS0-003 video course on YouTube. Watch the videos at 1.25x speed, take notes by hand - not typed, hand-written. Skip nothing in the threat detection and log analysis sections. That's where Week 1 lives. Don't touch practice exams yet. You're not ready and you'll just demoralize yourself.
Weeks 2–3: Deep Practice and Weak Spots
This is where you live in Jason Dion's practice exams on Udemy - grab them when they're on sale for $15, don't pay full price. Take one full timed exam, score it, then go through every wrong answer like a crime scene. Not just 'oh that was C not B' - figure out why the right answer is right. CySA+ trips people up hardest on two things: SIEM log interpretation and the proper order of incident response steps. Everyone thinks they know IR until the exam puts a weird scenario in front of them. Spend dedicated time on MITRE ATT&CK framework mapping and understanding what a false positive actually costs an organization. Those show up constantly.
Week 4: Exam Simulation and Final Review
Run full 165-minute timed exams every other day this week. Treat them like the real thing - no phone, no pausing, sit somewhere quiet. You're training your brain to think under time pressure, not just testing knowledge. After each one, review wrong answers only. Don't re-read chapters at this point - that's a waste of your last week. If you're consistently hitting 80% or above on practice exams, you're ready. Stop studying the night before the exam. I mean it. Your brain needs to consolidate, not absorb more. Whatever you don't know on Day 29, you're not going to learn on Day 30. Trust the work you put in.
Day-Before and Exam-Day Checklist
The night before: light review of your handwritten notes for 30 minutes max, then stop. Eat a real meal. Sleep 7-8 hours - this isn't negotiable. Exam day: bring your government-issued ID, arrive 15 minutes early whether it's in-person or online proctored. Eat before you go. If you're testing remotely, test your webcam and internet the night before - not the morning of. During the exam, flag and skip questions you're stuck on, come back to them. Don't let one hard question eat 10 minutes. Trust your first instinct on scenario questions more than you think you should. Second-guessing is how people fail.
