This man changed my life. 15 years ago, I didn't think I could ever become an electrical engineer. I don't know if I could ever thanks him enough.
Nice that he can teach someone who understands but any teacher who this any question is dumb shoudnt be teaching. I found him very ineffective.
Mr. Koval was the best teacher I ever had! Thanks Koval!
i had him in 7th grade, and then i left westlake...and he's the only teacher i remember and i still love him!

Koval is awesome you just have to be careful not to get him mad or ask dumb questions. I loved having him as a teacher. He's a funny guy.

ALL I HAVE TO SAY IS DONT EVER GO TO REVIEW WITH THIS MAN. IF YOU DO GO AND DONT UNDERSTAND SOMETHING WHICH IS THE POINT OF REVIEW, HE GOES BOLISTIC
