One of the best teachers I've ever had, best science teacher by far. Vastly intelligent, pedagogical genius, keen sense of humor, appropriately cynical towards stupidity, probably having the time of his life in retirement. He is greatly missed.
By far the best science teacher I've ever had. He loves what he teaches and definitely knows what he teaches. It's such a shame he's not teaching anymore! I love him!
An amazing teacher. My favorite at North. Very helpful. His honors class is hard but he works with you to help you understand the material. A very nice guy.
Mr Kost= Amazing. The world needs more teachers like him!
Mr. Kost is probably one of the smartest teachers I have ever had. Even though his class is difficult he is always willing to help you. His honors class is very challenging, so if your used to getting As, dont have a melt down if you get a B or C.
MR. KOST IS THE BEST TEACHER I HAVE EVER HAD!!!!!! he is seriously one of the sweetes people, even though he tries to act like he's not sometimes. it was my last class of the day and my favorite. i've never had a better science class. i seriously love him to death!!!!!
So what if i have no idea what i'm doing? He's always ready to help if you ask him, and he doesn't care if you break stuff.
Mr. Kost is the coolest teacher i have ever had..especially when he stands on the counter to show us about the periodic table!
He's the sweetest man ever! and one of the coolest and best teachers at North. Makes the science department not so much of a joke.
he is the most awsome teacher in the school!!! sometims the work is really hard though
had Mr. Kost as a teacher many years ago...he was awesome back then too. I STILL have the periodic table memorized!
same thing that everyone else is saying.... MR KOST IS AWESOME!
Mr. Kost is the best teacher ever! Any teacher you can laugh with and not at is great! he's more than a teacher, he gets on a personal basis with everyone!
Mr Kost is one of my fave teachers ever. AP Chem was horrible, but he was HILARIOUS. I have so many memories from that class. He gets 2 kno u personally & helps
GOOO Mr Kost! HE is the best teacher ive ever had! and he is a way cool dude too! I never really liked science until his class but he made it really fun!
Best teacher I've ever had. Very kind and generous man. I hated chem but I loved coming to class just to chat with him.
Definetly one of the best teachers i have ever had, such a wonderful person, and absolutely hillarious guy....makes chem enjoyable....great way to begin my day
there are no words to describe how cool he is. its a hard course, but he makes it fun and easy.
Mr. Kost is mad! i love it. watching him jump around, getting all excited about electrons and the periodic table..his class is the best way to start the day
Best science teacher I've ever had. He actually makes the class fun.
Mr. Kost is by far the best teacher i have ever had. his enthusiasm helped me so much and i love him hes the best!
