Yes! Fear not! Since I intend on providing a course of similar depth to an academy course, we will go from the very basics (what is a network?) to the end (how to create a full network with routers, switches, WAN, etc.). In fact I have met several people with experience who have had a more difficult time trying to erase incorrect assumptions or knowledge, than someone who knew nothing at the beginning. Starting fresh is good! For those of you who are familiar with the CCENT certification, this CCNA course will cover CCENT, which will basically be the first half, and the rest of CCNA is the second half.
