He was the economics teacher. He had helped me throughout my four years of high school. I could also come in any time for extra help and he was a very knowledgeable man. He also gave me advice on what to do in the future. He overall was my second favorite teacher.

Here's the thing. People dont like him because he actually makes you do work. if u pay attention, take notes, and study, it is sooooo easy to get along with him. i hate learning about gov. but with him it was enjoyable. he was funny and was open to debates about anything. he was one of the best teachers i have ever seen. and ppl who disagree are the ones failing his class because theyre too dumb to do anything else!!!!!!

Mr. Koszarek was one of my favorite teachers in high school. He ignited an interest in Russian history that lasts until this day. Most students don't like to be challenged--if you don't you won't like his class, but if you do you will learn a lot!

I graduated in Honors at Slinger High School and his West Civ class my Freshman year was the hardest class I took. I did not understand his teaching or videos that he made us watch. I ended up with a D in the class and its the only D i recieved in my high school career. This came from his lack of teaching and caring about helping his students out.

He's an all right teacher. He just expects you to do your work.

His tests are really hard and demanding, but I think he is a good teacher. He lectures which makes it a little more easier, but there is a lot of map memorizing

he was a nice teacher, but watch out... his questions on tests are worded oddly so you get them wrong...
