Most people don't like him because he doesn't just give out grades to people who don't deserve them. If you're actually smart and devoted youll do great. By far the smartest science teacher in hills. Such a kind guy too.

he cant explain things. He is better one on one.when taking notes in class he reads them to u and u copy, nevr goes over questions and doesn't let you ask questions. if you do he ignores and moves on. He is a bore the only way u pass his class is if u are dedicated to review and teach yourself chemistry or get a tutor. his tests are HARD. A lot of ppl cheated in his class but didnt pass the regents.he also mentioned in like 30yrs of teaching only one of his students got 100 on the regents -_-

he knows his stuff. he does not want to explain things twice so if you dont understand it, that sucks for you. His tests have nothing to do with what we learn and the way he teaches is by giving lectures. I dont like him and neither do my classmates

I had Mangru for Sagan Chemistry. He is honestly one of the best teachers out there, but unfortunately he is retiring. The class grades are extremely fair and if you improve dramatically at the end of the year he will bump your grade up.

i am a 98 average student who got an 82 in his class. If u can transfer you should because the only time he is really helpful is afterclass or lunch periods. If u are stuck in his class, i say study ahead of time so youll understand in class

Mangru has seriously lightened up this year. He make the class actually fun and he teaches chem pretty good. He's not the best chem teacher in the school (that would be mr.albert) but hes second best and thats not bad at all! If you study and pay attention then you're pretty good. I've freaked out all year and still do cuz i still have him but im hoping that i'll pass the chem regents with at least a 90 if i focus and start understanding since we only have one more topic to go. Don't worry! :)

Thanks to Mr Mangru, I got into poly. He made me understand how college worked, and it helped a lot. He always screamed at me, I hated him so much. but thanks to him, I raised my grade from failing to a 99! And I didn't like science at first, but he made me fall in love with chemistry and I'm now majoring in something closely related to it. I found out what I wanna be thanks to him. Idk how and why other people think he sucks, but he's the best science teacher i've ever had! Highly recommended~

He is a good teacher academic wise, but he can just be a pain in the neck to deal with. He makes you stand in front of the room if you only talk once, like do I seriously look like a kindergartener to

it's very hard to understand him, he has a very heavy accent. but if you take a few mins after class, he'll try his best to explain everything to you so you'll understand, and his test are just copies
