I had Mr. Kaelin for Pre-Calc, and it was literally the easiest class ever. Even though I cut his class 10 times, did no homework and did average at best on his tests, he gave me a 65 on my final grade. The only thing is that his class gets boring at times, but you can play on your phone and he won't reprimand you in the slightest bit. Just pretend you are listening. That is it. Participate a little too. Honestly, he is so nice, and he is so chill. All his tests are MC, easy 90 plus. I <3 Kaelin

I had Mr. Kaelin for Pre-Calc in my senior year and for Geometry in my sophomore year. Math is not my thing but somehow when he teaches it, I understand and I do well. He is the best Math teacher that I ever had.

Great guy. He accepts any homework late for the term. Kaelin also explains how to do certain geometry questions well that may popped out in the regents. He's very nice and is able to interact with other Tech kids well. Only thing is the monotune but you will understand him fine. Just do your hw, listen, take class notes, and you should be fine.

Let me start off by saying that geometry is not my thing. But, Mr. Kaelin is really nice. He's nice with grading and it's really considerate to his students. Just do your homework, copy the notes he writes on the board and study for his tests. You will get a decent grade.

Amazing teacher. Makes everything clear. I was afraid of geometry because i heard proofs were hard but he makes them seem so easy. He's also like my only teacher that accepts late homework so I don't have to worry too much if I ever forget to do it.

Mr. Kaelin was my teacher and cosa 10 yrs ago. He was great even with his 9x joke. I don't know if he still does it, but us old schoolers laughed at the corniness of it every time. Mr. Kaelin was not only a good teacher, but was always available to his students when they had problems, no matter how busy he was. I spent many an afternoon in his office crying and being comforted by him. He is the reason that I graduated Tech, he had confidence inme when no one else did. Thanks for everything Joe.
