Thank goodness he is retiring. Mr. Bittner was probably my least favorite teacher i've ever had.
He makes the classes hard and he laughs at his own boring jokes.
He's a good teacher, but he grades harshly. Not my favorite teacher, but he's ok. Look out for small errors in reports and stuff. He takes alot of points off!
If you are willing to learn, Mr. Bittner is a great teacher that will help you learn a lot, and he will try to make learning interesting through applications.
