Boosted my Self-Confidence!

I am preparing for CCIE to upgrade my career. Before I found my theory knowledge was lacking to study CCIE. I was feeling depressed, but then I found NetworkLessons.com! The monthly fee is very affordable. I already learned CCIE and OSPF from your lessons. All topics area very clear, even on difficult items like LSA Types, Path Selection, Filtering, and Summarization. I got SO much self-confidence from your teachings! I believe I will get my CCIE number thanks to your lessons and explanations. Much Obliged and thanks!

NetworkLessons.com has become an invaluable resource for me. Of course, the official Cisco press books are just fine and cover all the material in thorough detail. The difference though is that Rene emphasizes the important topics that you really need to know in a real production environment. He gives you the meat and potatoes and does so in a way that's very easy to understand. My favorite thing about NetworkLessons.com is that I can use it as a quick reference when I am troubleshooting on the job. This is much better than lugging around official Cisco press books and sifting through pages and pages to find something specific I'm looking for.

Very Good

NetworkLessons.com has an amazing way simplifying complex materials without oversimplifying things. Nice drawings of the scenarios. I used their materials (and some other) to achieve CCNP level (RS) and am now using it to complement my CCIE studies. Their courses are ordered in a way that you can find answers to questions you got fast. I really recommend their materials!
