Passed Network+ (N10-009) first try — 747. Here's the study method that actually worked.
Just passed the N10-009 on my first attempt with a 747 (pass line is 720), and I want to give back with the approach that got me there, because it's different from the "just grind practice tests until you hit 90%" advice you usually see.
Background: Working through a networking degree, prior CompTIA certs under my belt. Studied hard for this one over several weeks. 5 weeks to be exact and 2 of those weeks were 18 hour days 7 days a week.
Resources I used (all solid):
Professor Messer — free, objective-mapped videos. Backbone of my concept learning.
Jason Dion practice exams — for realistic, scenario-style questions.
Andrew Ramdayal — good supplementary course coverage.
A YouTuber called DarkBird Tech — long practice-question walkthroughs where he breaks down why each option is right and the others are wrong. This one quietly mattered a lot (more below).
Claude (AI) — this was invaluable. After each practice exam I'd feed it my misses and it would analyze them, group them into weak-topic clusters (routing, DNS tools, wireless attacks, subnetting, etc.), and drill me on each cluster until it stuck. Turning a scattered list of wrong answers into a targeted, prioritized attack plan is a huge time-saver, and it made my studying way more surgical than just re-reading everything.
The core mindset shift — recognition ≠ mastery:
The single biggest trap is retaking the same practice test until you score high, then thinking you're ready. You're not — you've just memorized that specific set. A high score on questions you've already seen predicts almost nothing. I learned this the hard way on a previous exam.
What actually builds readiness:
Take each practice exam COLD, once. That first-attempt score on fresh questions is your only honest signal. Burn it, don't retake it for a "better number."
Drill your MISSES, not the whole test again. After each exam, pull every wrong answer and work it until it's locked. (This is exactly where having Claude cluster them by topic paid off — it found the patterns in my misses I couldn't see myself.)
Drill the whole family, not just the right answer. If a question's answer is OSPF and the distractors are RIP/EIGRP/BGP, learn all four cold — because any of them can be the correct answer or the trap on the real exam.
Prove the logic transfers. This is where DarkBird helped: I didn't memorize his answers, I absorbed his elimination reasoning, then tested whether I could walk that same logic on a brand-new question with a different scenario. If it transfers, you actually know it.
Subnetting to reflex. Learn the simple block-size method and TRUST it — don't overcomplicate under time pressure. Devices needed + 2 (network + broadcast) → round up to the next power of 2 → prefix. /30 = point-to-point. Drill it until it's automatic.
Exam-day tactics:
Do the multiple-choice FIRST, then go back to the PBQs with 30–40 minutes banked. PBQs eat time.
Memorize the acronym list in the back of the official CompTIA objectives PDF.
Domains 1 and 5 carry the most weight (~47% combined) — don't under-prep them.
Read the last line of the question first to know what it's actually asking, kill two obvious wrongs, then decide the final two on one precise fact.
Use the clock. Rushing is a silent killer — read each stem twice.
One extra thing that helped: I built my own offline drill app to hold my missed questions and re-shuffle them (both question order and answer positions) so I was recalling the concept, not a letter position. You don't need to build one — flashcards or a spreadsheet do the same job — but shuffling matters.
If you're on the fence: trust the method over the memorization. Cold reps, drill your misses, learn the why. Happy to answer questions in the comments. Good luck to everyone sitting soon. 🫡
