Good teacher. If you don't understand the material you will need to do the homework or ask him questions. Don't take his cynicism too seriously, he yelled at me all the time and I got a 5 on Stats and Calculus BC with a C in both of the classes. In the last month you do a bunch of AP review that makes the tests a breeze. He will always help you when you ask, and is extremely knowledgeable about the material he teaches, and is very passionate about it as well.
very tough. can be harsh and mean to students even if they don't deserve it, doesn't always answer q's well. personality is not the nicest, marks on tests hard to decipher and tests are extremely hard. i dreaded this class every day. that being said, he prepares you very well for the ap exam - i was pulling a C and still managed a 5 on the exam. stay on his good side. DO THE HOMEWORK AND CLASSWORK, pay attention in class, be polite, DONT bring in phones or backpacks he will see and be v angry
extremely difficult to work with, not approachable, not helpful, calls out students, discourages questions. do not recommend.
This man is amazing, though the material is tough AP Calculus AB. I have never had to get additional help ( so far) because he teaches the material like a true scholar. Be prepared to get homework every night but most of the assignments he assigns are not lengthy.
This man knows what he's doing. If you actually do the homework how you should, you'll be fine. If you ask questions in class, you'll be fine. If you don't do what he tells you to do, you'll struggle to get a C. That means you actually have to apply yourself in this class. Again, he knows what he's doing.
Very good teacher who truly knows his stuff. You will get Calculus if you have "Iron Mike"
As a teacher, Mike Koehler is amazing. He explains the logic and reason behind the math he teaches. His tests are difficult and demanding, but his teaching is worth it.
Mr. Koehler is the best math teacher I have ever had, ever. He seems to know everything about math, and if you can get on his good side he's a really nice guy.
Mr. Koehler is an awesome man. He is a calculus and statistics god and one of the nices men you will ever meet.
He's very intelligent and hilarious to have as a teacher!
He yells at kids and makes them feel bad about themselves at times, but he is a good teacher.
This man is a god, the greatest calculus teacher in all the world
