Look, I’ve been doing this certification thing for years. I know the grind. I know the flashcards, the practice exams, the YouTube videos at 1.5x speed because Professor Messer talks like he’s got all the time in the world and you don’t. I know what it takes to pass these exams.
So when my coworker told me they passed both CompTIA A+ and Network+ after one insane day of studying, I should’ve been skeptical. I should’ve been annoyed. I should’ve rolled my eyes so hard they got stuck.
But here’s the thing. I’m actually proud of them. Because they did something most people who cram for these exams completely miss. They didn’t just memorize definitions. They lived in the labs.
The One Day Cram Session That Actually Worked
Let me paint the picture. My coworker decided on a Tuesday that they were taking both exams on Wednesday. Not spreading them out. Not giving themselves a week between tests. Both. Same day. Back to back if the testing center would allow it.
This is objectively a terrible idea. I want that on the record. CompTIA A+ has two exams alone. Core 1 covers hardware, networking basics, mobile devices, and troubleshooting. Core 2 hits operating systems, security, and operational procedures. Then Network+ wants you to know subnetting, routing protocols, network topologies, and about seventeen different cable types that all look the same in the exam photos.
Most people spend weeks on this material. Some spend months. My coworker gave themselves 24 hours.
And somehow, it worked. But not because they got lucky. Not because the exams were easy that day. They worked because they focused entirely on the part of these certifications that actually matters.
They Skipped the Textbook Theater
Here’s what they didn’t do. They didn’t read a 900 page A+ study guide cover to cover. They didn’t watch every single training video in sequential order. They didn’t make color coded notes or highlight half a textbook in yellow like that somehow counts as learning.
They opened up every hands on lab they could find and started breaking things. Virtual machines. Old hardware sitting in the storage closet. Network simulators. Packet Tracer scenarios. Anything they could click, configure, or completely screw up.
When they hit something they didn’t understand, they looked it up. Learned just enough to move forward. Then went right back to the labs.
No lengthy study sessions about OSI model theory. They built network diagrams and watched packets move through layers. No memorizing port numbers in a vacuum. They configured actual services and saw which ports opened. No reading about RAID arrays. They set them up, watched one fail, watched the array keep running.
The Labs Are Where the Knowledge Actually Sticks
CompTIA loves their performance based questions. You know the ones. They drop you into a simulated environment and say “fix this” or “configure that” and you better know what you’re doing because there’s no multiple choice safety net.
My coworker walked into those questions like they’d seen them a hundred times before. Because they had. Not the exact scenarios, but close enough. They’d already troubleshot boot failures. They’d already configured VLANs. They’d already set up DHCP scopes and watched devices pull addresses.
The theory questions? Those were almost easier. Because when you’ve actually done the thing, the theory stops being abstract. You’re not guessing which answer sounds right. You’re remembering what happened last time you tried it.
Why This Approach Works Better Than You Think
I’m not saying everyone should cram two certifications into one day. That’s chaos. That’s asking for a migraine and a credit card charge when you fail and have to retake.
But the lab focused approach? That part you should steal.
Most people study for these exams backwards. They read everything first, trying to build this complete theoretical foundation before they touch any actual technology. By the time they get to labs, they’re exhausted. They rush through them. They treat them like a checklist instead of the actual learning tool.
My coworker flipped it. Labs first. Theory as needed. Hands on repetition until the concepts stopped being concepts and started being muscle memory.
When you’ve physically swapped RAM, you don’t need to memorize which slots to use for dual channel. You remember. When you’ve configured a router five times, subnetting stops being this scary math problem and starts being that thing you just do.
The Part Where I’m Actually Proud
Here’s why I’m not mad about this one day miracle. It wasn’t a miracle. It was focused, intense, practical work. The kind of work that actually translates to the job.
Because let’s be real. Nobody at work cares if you can recite the OSI model layers in order. They care if you can troubleshoot why the printer won’t connect. They care if you can figure out why half the office lost network access. They care if you can walk someone through a boot issue without making them feel stupid.
Those are lab skills. Those are hands on skills. Those are the skills my coworker drilled into their brain during their insane one day sprint.
And now they’ve got the certifications to prove they know what they’re doing. Not because they memorized textbook definitions. Because they can actually do the work.
What You Can Learn From This Chaos
Should you try to pass A+ and Network+ in one day? Absolutely not. Please don’t. Give yourself at least a week per exam. Two weeks is better. A month is reasonable.
But should you spend most of your study time in labs instead of textbooks? Yes. Completely yes.
Build things. Break things. Fix things. Run through scenarios until you stop having to think about each step. Use Cisco Packet Tracer for network simulations. Spin up virtual machines for operating system practice. Get your hands on old hardware if you can find it.
Treat the theory as reference material, not the main event. Look things up when you need them. Build context around the concepts instead of memorizing them in isolation.
And if you work with someone who somehow pulls off an impossible certification speedrun, don’t assume they got lucky. Ask them how they studied. Because they might have figured out something the rest of us took way too long to learn.
My coworker did. And honestly, I’m impressed. Even if I’m never letting them live down the fact that they scheduled two major exams on the same day like some kind of certification adrenaline junkie.
Big Dog Cert
Alright, lemme give it to ya straight. No sugarcoating, no corporate fluff, just the real deal. I'm Mike. Fifty years on this planet, and I've done it all. I started out in IT back when "the cloud" was just what you saw out the window, worked my way through HR (yeah, I've been the guy who had to sit across the table from people and keep a straight face), and then did a stretch in sales where I learned real quick that if you can't sell yourself, nobody's buying what you're pitching. Three careers. One guy. Zero patience for textbooks that read like they were written by robots.
