Study timeline
How long it takes.
Honest estimates. The platform tracks your progress so you can see when you are ready, not just when the calendar says you should be.
| Hours/week | Weeks to ready | Suited for |
|---|---|---|
| 5 hours | 16-20 weeks | Side-time, working tech |
| 10 hours | 8-12 weeks | Already comfortable with A+ topics |
| 20+ hours | 4-6 weeks | Dedicated networking focus |
Sample question
From the quiz pool.
Domain 1.0 Networking Concepts
A workstation has IP 192.168.10.45 with subnet mask 255.255.255.224. What is the broadcast address for that subnet?
A192.168.10.31
B192.168.10.63Answer
C192.168.10.95
D192.168.10.255
Why
Mask 255.255.255.224 is /27, meaning 32 addresses per subnet. The host 192.168.10.45 falls into the subnet 192.168.10.32 to 192.168.10.63. The broadcast is the last address in the range, 192.168.10.63.

Questions.
What is live for Net+ today?+
Everything. The 25-lesson classroom curriculum kit, plus the full platform: Adventure scenarios across all 25 lessons, 500 Q-bank questions across all five N10-009 domains, performance-based practice across all five RTJ interaction patterns, 768 flashcards, and the full Practice Exam with a Mastery Index and evidence-quality label. Teacher and Academy subscribers can download the kit from /teacher/curriculum.
Do I need A+ before Network+?+
Not required by CompTIA but strongly recommended. Network+ assumes you already know basic IP addressing, OS, and hardware fundamentals. A+ on Revy's Tech Journey is fully live across all six study surfaces if you want to start there first.
Is Network+ worth it over Cisco CCNA?+
Network+ is vendor-neutral and broader. CCNA goes deeper into Cisco hardware specifically. Most learners do Network+ first then decide. We do not cover CCNA at launch.
Is the exam mostly memorization?+
Less than A+. Network+ is heavier on troubleshooting scenarios, which is exactly what the Adventure scenes and the Practice Exam performance-based questions are built to drill.
