Failed the CVSS the first time with a 68% and it stung. I thought I understood IP camera specs and analog signal routing well enough but the NEC code questions and structured cabling topology section hit me out of nowhere. Spent 4 hours a day for 3 weeks before the first attempt and clearly I wasn't focusing on the right material.
Second time I restructured completely. Went deep on coax vs fiber attenuation loss specs, made flashcards for every cable run distance limit in the AVIXA standards, and timed myself on every practice question instead of just reading through them. That shift alone probably accounts for most of the improvement.
Ended up scoring 81% on the second try. The troubleshooting scenario section — about 20% of the exam — was where I picked up the most ground. First attempt I barely touched it. Second time I treated every scenario like an actual field call and the answers felt a lot clearer.
If anyone's studying right now and wants to compare notes on the cabling specs, happy to share the flashcard deck I built.
Failed at 71% on my first attempt, retaking in 3 weeks. Your point about timed practice is exactly what I needed to hear. I've been reading through questions slowly instead of drilling under pressure. Changing that now.
The troubleshooting scenarios clicked for me once I stopped treating them as theory questions. Ask yourself what you'd actually grab first if a client called with that problem — the right answer usually follows from there.
Congrats on the pass. The NEC code questions hit differently if you haven't done field work — that stuff doesn't come from reading alone. I got through with 79% and the structured cabling topology section took more out of me than anything else on the exam.
What study resources did you use beyond AVIXA material? I'm sitting for this in 7 weeks and the camera compression ratio and signal resolution questions are where I keep losing points on practice tests. Most online prep feels either too basic or assumes prior field experience.
The NEC code stuff got me too on my first attempt. What finally clicked was stopping trying to memorize the code sections and instead actually understanding the "why" behind the requirements -- like once I understood why certain cable distances exist for structured cabling it stopped feeling like random numbers I had to cram. I also spent way more time on the topology section than I wanted to, drawing out star vs bus vs ring diagrams until I could do it in my sleep.
Honestly the thing that made the biggest difference was doing timed practice runs in the last two weeks. I wasn't running out of knowledge on my first attempt, I was running out of time and second-guessing myself. Forcing myself to answer and move on, even when I wasn't 100% sure, changed everything. Good luck if you're still grinding through it -- it's definitely passable, just takes the right approach.
The NEC code stuff got me too on my first attempt. What changed for me was actually slowing down and working through practice scenarios instead of just reading the codebook sections. Like, I'd see a question about cable distances in a structured cabling run and I'd freeze because I'd memorized the numbers but didn't really understand why they existed. Once I started treating every practice question as a mini troubleshooting problem it started clicking.
Congrats on pushing through and taking it again, that second attempt anxiety is real. For anyone still studying, don't skip the topology section thinking it's just diagrams. It's not. I spent maybe 30% of my final week on nothing but star, bus, and hybrid scenarios in context, and I think that's what pushed me over. The exam wants you to apply it, not recite it.
