I've had him for both Cisco and autoCAD. He's fairly easy, a lot of people find him hard because he teaches a hard course (cisco) and that's why they say he's hard, but they are tough concepts to get your head around. He flips when he catches people playing games on the computers though, but he lets us play 10 mins after class. He's a good teacher in my opinion. A lot of teachers dont let the kids play games at all :S.
A really nice guy!! Very helpful, and always makes me happy to come to class.
