He's an odd dude, pretty funny, but is pretty difficult. He seems to be pretty closed off but is extremely helpful at extra help, I definitely recommend going if you're struggling!
Kettler is a great guy. Gives extra help if need it at any time. Tough grader, though.
I highly recommend you DO NOT slack off during his class. His tests are largely based of class material and the notes he makes you take so always pay attention. He likes students who talk and joke around with him, and raise their hand during class. That being said, don't fool around and be an idiot because then he will despise you. Also, he can see you uusing your phone from a mile away.
Got to love the weird sense of humor. Tough grader and a lil stand offish but overall nice teacher
Mr. Kettler is the nicest teacher ever. He really helps you a lot and gives extra-help at any time of the day that you need it.He is a great man and never really gets mad, he just smiles. I will miss him next year!!!
If your a good student and actually try to pay attention, he won't be so mean.
really nice guy and a really good teacher. he's always offering to help out
He is an amazing teacher! He really goes out of his way to help students. He has helped me out in extra help afterschool like 4 times already!
mr. kettler is a very strong, strong man. you'll also note how inept he is at basic things. but cool nonetheless.
He gives you notes. then you ask him questions and he wont answer. He just smile and shakes his head. YOUR SUPPOSED TO TEACH US!!! so frustrating :(
good guy, class is tought tho (chem) always works in coliation with Dornicheck who is the other checm teacther
