This teacher works hard but students that don't try are the ones who don't do good in class or don't have the time to study or they are the ones who don't pay attention in class.
this teacher helped me to earn a 5 on the AP calculus exam, he is truly an inteligent guy, a little strange sometimes, but he's a really good teacher
Chal made me LOVE math. Not that he forced me, he is just that great!
Definitely plays favorites, but if you can get on his good side, he's cool.
