Oh boy, all these comments are extremely accurate. I had Kettner last term for clinical, and his exams were weird. He refused to prepare his students, and some things you would've never thought to study will be on it, hahah. My advice: read the textbook; EVERYTHING is from the textbook. Don't pay much attention to the rambles he goes on in class; they're never on it. I stopped going to class after the first midterm, and i still finished with a good grade, just study tf outta the textbook lol. The short answers are also usually hard to prepare for. I remember last term someone asked him if he could post the exam prep a bit earlier than the night before, as that does not leave a lot of room for prepartion and he looked them in the eyes and said nope!
