It is unclear, sometimes, whether he is joking or not. But once you get used to him, he can be a really good teacher and person. Don't let him fool you, he's not really "Hard Core"
"Hard Core Korbel" is a sweet guy. He really cares about the kids and U.S. History. Especially in Psych, though, what he wants is unclear; it has to be one way. Busy work, too.
He's a very good teacher... for anyone reading this that has the opportunity to, I urge you to take his psychology course, you'll definately enjoy it.
Your rigor will pay dividends later in life. You are AWESOME!
Great guy you should take him as a teacher at least twice!!!
Mr. Korbel, you're awesome. You helped me get 5 on AP test. You're funny too!
