TCP Segment
App data gets a TCP header — source port, destination port 443, sequence numbers.
Early preview access.Lessons, labs, topic notes, charts, and practice trainers are open now. Full practice exams (400+ original questions) are still rolling out and aren't included in this preview.
The 10-week roadmap
Follow the packet from foundations to exam day — every station on the board is a week you can open.
Learn by doing, right now
Interactive trainers you can open today — subnetting, routing, wireless, automation, and more. Here's one running live.

CCNA Practice Exams
Four 100-question blueprint-weighted exams, random weighted quiz, domain drills, tiered scoring (70% / 82.5% / 90%+), and local history tracking.
Every core topic, covered
Each exam topic links to a trainer, a unified guide, or a lesson — pick the format that makes it stick.
Built for understanding, not memorization
Most prep stops at flashcards. This site is built around how frames and packets actually move — with original notes and questions, not braindumps.
A full path, not a pile of links
Ten weeks with objectives, lessons, labs, and weekly quizzes — mapped to the official CCNA blueprint.
See traffic move
Packet walks, encapsulation labs, and animated topologies show switching, routing, ARP, and TTL on the wire.
Trainers that expose gaps
Subnetting gates, routing-table reading, TCP timelines, NAT/PAT, and ACL placement — built to catch weak spots early.
One guide per topic
Unified topic notes, charts, and cheat sheets merged from several study sources into a single on-site reference.
Aligned to Cisco's blueprint
The authoritative exam blueprint from Cisco — domain weights, objectives, and what Cisco says is in scope for CCNA 200-301. Always verify your study plan against this page before you sit the exam.
Pick a starting point
Week 1 if you want structure. A packet walk if you learn by watching traffic. Resources if you already know where your gaps are.
