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
Mangru is the only chem teacher who knows his stuff. He's the smartest out of all of them even though he's not always kind. Great teacher and really smart though!!
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.
BEST CHEM TEACHER OUT THERE! didn't really like him at the beginning of the year but he's growing on me! His stories are hilarious and is always there to help when needed.
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~
Are you guys kidding me??? He is only the best chem teacher out there who will actually prepare you and go in depth and over. HE IS THE BEST. His tests are super easy and when you take the regents, 90
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
I regret being in his class for a whole year, i learned absolutely nothing, and i don't recommend students to take this chem. teacher(unless you're a science wiz or a carl sagan student)...
i don't know about anyone else, but i love this guy. one of the best science teachers i've ever had. because of him i understand chemistry :)
haha the pressure cooker is always on never shuts up right?
He's definatley not one of the popular ones, but he's a great teacher. He actually has a method and inspires you to learn chemistry and master it. Hey, Mr. Mangru if you are reading this, BE PROUD
mangru is the best teacher ever. he knows the subjest and teaches very well. in fact he simplifies the material so one can understand it. BEST CHEM TEACHER.
Lol he's one funny guy. Can't understand him though.
This is a man who knows his stuff very well. At least he's not clueless about the subject. And he tells bad analogies that link to chemistry but that doesn't really matter :)
His tests were very hard, you needed to learn from that prep book and bring it everyday, but he passes you if you come everyday, get 40+ on tests/quizes, and dont talk to much.
Mangru's a pretty nice teacher and he can teach well but hes gonna lose his mind when you ask him a question. Since he teaches so well, i dont have to touch my chemistry textbook.
He is capable of teaching well but yells at students a lot. If you make a mistake during lab for example, he'll raise his voice..and after a while you get irritated
mr.mangru is the best, even though he hates wen pll ask questions, he never smiles well there is an exception i made him smile once.haha, his class can get kinda boring
the best chem teacher of the 3, moves fast, and makes a bit easier, but his lessons can become a little boring. his analogies are great and he can sometimes be funny
mangru's awesome, its just that some are you just dont want to listen. Go to earth science or drop chem. Hes a good teacher.
I had all 3 chem teacher and he's the best. lot's of notes, moves quickly, explains well & finishes the stuff early with lots of time for review
He is a smart teacher but he cant explain many of the stuff. He just doesn't care sometimes. I know he's old but maybe he should retire.
he is wonderful ans understanding. Makes students enjoy the lession and laugh at some of his methods in memorizing important ideas.
Very helpful and explains concisely, but is sometimes lazy.
He is the best teacher ever.... explains everything so clearly .... U go Mr Mangru
Couldnt understand anything he said, and he didnt explain himself at all. I transfered out of there pretty quick
great teacher...just gotta pay attention, i suggest takin a seatin the front.....
really enjoyed him as a teacher and explained everything so well in a concise and coherent manner. Eventhough has an accent, i could understand him.
Mr. Mangru is the best!!! I just simply love him! Finally, i had a teacher who explained everything so clear, that i didn't even have to open a book once!!!!!!
he is okay, but with his accent i can't really understand the things
hes very smart & but his way of teaching is hard to understand. but his tests are easy since he takes it out straight from the textbooks. study A LOT !
he is ok. I learned something from his class but i failed all the test but he is a pretty good teacher
He absolutely horrible. A very very evil man! I have never had so much dislike for a teacher before. He's probably the worst teacher in the world!!!!
hate this guy accuses people of cheating, babbling infants are more articulate
a teacher whose unclear and difficult to understand. he should go back to work as a factoryworker
