If this is the Kostel that I had 86-91, then he's a great teacher. Math is a hard subject that requires discipline, not a soft easy time.

As much as he might not be the best teacher in the world, but whats the purpose of being in a math honors class if you can't get by alone.

If you're scared of him you're a wimp, he's a good teacher, people can learn a lot if they'd stop whining...
