He seemed like a good teacher for awhile but slowly started to joke around to much and then he emailed my mom because I was late in the morning twice and I wants to even that late it was 5 minutes at the most but he emailed her saying that my parents should change there parenting style like I don't think he should be saying that

Math is in no way my strongest subject, but teachers in the past have helped me through it in a kind, open way. This man is honestly the worst teacher I've had the displeasure of having. He is wildly unprofessional in the way he lashes out against students and openly discusses people's grades in completely inappropriate settings. On top of that, his teaching style is completely unclear, and his tests are hardly related to class. If you see this man's name on your schedule, run; don't walk.

Dr. B is one of the toughest and best teachers I have ever had. His calculus class is intense and at times makes you want cry. However, he loves anyone who will work hard and wants to see you succeed

Calls home on everyone for everything and when he does he's to f'n old to remember the students he's calling and says you did things you didn't and he spoke to you about it (which he dosen't). Unless your a real math geek, if this man's name is on your schedule: DROP HIS CLASS!!!!!

I had him for two years and was very happy to see his name on my schedule a second time. We were one of his first IB classes and I got a 7 on the Methods test! Now I'm a math major in college and I have to believe he helped me get there.

His tests, and quizzes are hard, but stay for extra help, and he will help you. He makes you ask for help, he doesn't babysit you.

I think Dr. Bernstein is a fairly good teacher, I had him for two years in honors math. He isn't a very outgoing guy or particularly nice guy, but he is friendly, and he is a great teacher. He does tend to play favorites.

He's a very nice person, unless you get him mad which is hard to do anyway, and Visual Basic class is fun but he doesn't give us a chance to take notes.
