What Our Clients Are Saying:

Donald L Simpson

Comprehensive Networking Foundation

One of my favorite features of the site in general is the context sensitive keyword search feature in the upper right hand corner. This is my first favorite resource when looking for information on a topic I am unclear of. The site provides comprehensive coverage of all the CCNA topics. I haven't received a zero search result yet for any keyword searchs I've done. The course material is clear and concise with Rene giving video white board explanations making abstract networking concepts appear tangible. If you are looking for an entry point into the world of Cisco routing and switching, comprehensive content provides the foundation for CCNA and beyond.

Just Perfect

I like the way that Rene organizes the lessons and the courses. His explanations are clear and with simple examples. It's just perfect and very easy to understand. I would like to recommend for everyone who is interested in networking.
