LOL, this man. Everyday he would always take his sweet time just setting up his laptop, projector, and his notes. By the time he would finish and be ready to teach the class the bell had already rung. True story.

Excellent teacher and always listened. Tests were fair if you studied and did homework. Loves his dog and has a nice ponytail. One of my favorite teachers at Applewood.

Well Mr.Kosow is a hardass no doubt about it, but to say he doesn't care about his students is inaccurate. He likes to test his smarter students and really dislikes his more lazy/stupid stupid students. I would say that he has high expectations of his students but for the most part is pretty good. P.S he may say Quantum mechanics is useful for university but its all BS

He's a great teacher, if you do your homework and understand the topics you'll do fine and you shouldn't blame him for not teaching properly because you also have to study on you own and make sure you have a good understanding of chemistry

Mr.Kosow, he is hard at time, well, all the time, but this teacher knows what hes talking about. Just because he makes a simple question so advanced doesnt mean hes a bad teacher. Few things, when your answering a question, he might ask little sub questions of that question. Also, he will make you look stupid at one point. He also is a joker:P

He wasn't THAT bad, makes you nervous or look stupid when attempting to answer his questions, and you never know exactly what kind of answer he's looking for. Found his tests fair.. then again, i did pass with an A...

ahh what can i say about the school's worst fear (well second to mr. charmourian), though at times he can lack respect for his students, he overalls knows his stuff...very intelligent person, but he should keep in mind, we're not all as intelligent as he is, if you've had a bad teacher who taught you nothing for a whole year, beware of mr. kosow

Yes he's a hard marker with high standards and expects people to become self learners, but he can definitely prep us for university.

Although it is unfair as Mr. William's class hardly had any unit test but it will be helpful for us in University. We are more likely to survive

Mr. Kosow likes students that are self learners. He would only help those who comes for help. He should be more forgiving if he wants to be everyone's favourite
