Worst teacher I've ever had the displeasure to have had. It's obvious he doesn't like teaching or kids.
When he teaches you want to go to sleep. He never explains himself and when you ask him a question he either says that it matters not or tell you to stop talkin
He is a really good guy, althought when he taught it could get a little boring, he teachers well and you can talk to him like a normal person. Great NSI.
