No videos. On purpose.

This is a text-first course that links out to the best supporting material on the internet instead of trying to replace it. The goal is to make this the best course on ccna prep you can find — even without producing a single minute of custom video.

Exam-focused but understanding-first

This course is designed to help you pass the CCNA. But it teaches concepts, not just answers — because understanding networking makes every exam question easier.

Packet Tracer recommended

Cisco Packet Tracer (free) lets you build and test network topologies without physical hardware. This course references Packet Tracer exercises throughout.

Links to official Cisco documentation
