we are doing the IT essentails in my computer science class....its ok but it is kind of out dated(stuff is from 2003....) you can do it but i wouldn't rely on it to learn everything...imho google or even this forum is probably better
I took it back in high school and it wasnt too bad. But i'm taking it again in college to get a review on it, and it's alot more complex. I tell ya, subnetting is the worst thing to do by hand
