Hany can be absolutely brutal. If you don't attend class or don't do well on quizzes, he'll keep an eye on you. For the physics topics, look them up on YouTube because he can't explain them well. He teaches every other topic pretty okay, and you can succeed in the class as long as you stay on top of the homework. He offers many practice tests.MATH1342 2026-05-05 01:00:45 +0000 UTC
Baseline professor. Is very enthusiastic about teaching but can be a little blunt and rude sometimes. Just fine.1342 2026-04-16 15:54:38 +0000 UTC
Highly recommend Professor Sadaka. He has his own teaching style, and I really enjoyed it. His lectures are clear and easy to follow, and he does a great job of helping students understand the material. I learned a lot from his class. Would definitely take him again!MATH4581 2026-04-11 00:54:34 +0000 UTC
Shoutout to the person who said “if you're not religious pick a god a pray to it.” Undoubtedly the worst class I've had at northeastern. Barely any office hours, annoyed when you ask questions, and the exams had content I swear I'd never seen before. Hanai would let some students retake exams but not others which was frustrating to say the least.MATH4682 2025-12-07 17:17:06 +0000 UTC
Professor was extremely difficult to work with. He implemented a retroactive attendance grade deduction mid-semester that significantly impacted grades, without clear communication in the syllabus. Material and lecture notes was decent on their own, but the professor himself was horrible to work with. Very rigid, unapproachable, and at times rude.MATH3081 2025-05-09 20:12:16 +0000 UTC
Just a straight forward professor with some strict rules regarding tests and attending the class.IE6200 2023-12-11 18:18:51 +0000 UTC
Pretty standard Calc 2 teacher. Mostly just does examples and very rarely explains the theory, but if you ask him to he will. He's super passionate about Calc 2 and made me want to go to class even though it was at 4:30.MATH2321 2023-02-27 13:33:16 +0000 UTC
He is a school teacher, not a professor. He doesn't do what he says. Would definitely not take again. Method of teaching isn't up to the professors levelCALC1 2022-02-01 23:00:11 +0000 UTC
This dude was probably one of the worst teachers Ive ever had for math. In fact, he made me hate math so much that I switched my major. I have never seen such irresponsibility when it comes to teaching consistently across all his sections, and honestly frick this guy. I b failing his quizzes bc he did not provide quality teaching. Fat thumbs down:/MATH2105 2020-11-20 18:24:36 +0000 UTC
Hanai. Is. A. Bro. I had him for calc 2 and he was very good at getting his point across, the only think is he can be a little scatterbrained during lectures. He gives weekly quizzes but they are VERY easy and never anything surprising. He will drop a quiz or give a bonus make up quiz if the class does bad too. Take him any chance you get.MATH1242 2017-04-13 11:20:52 +0000 UTC
Is passionate about teaching and supportive of students' desire to learn. He is a fair and clear marker and explains things in a way that you can easily understand.MATH1231 2016-01-16 20:15:35 +0000 UTC
Extremely charismatic. Has a thick Egyptian accent but it's easy to understand and not an issue. His teaching isn't always effective and quizzes and tests can be tough. However, if he sees you trying he'll give you a lot of ways to make up points. DO NOT use phone or talk in class or he will personally dislike you. The textbook is for homeworkMATH1215 2015-04-17 15:41:23 +0000 UTC
one of the best instructors i've ever had! if he sees youre trying, he gets out of his way to help you out. grades fairly. go to class and pay attention and you will pass.CALC3 2014-06-12 14:33:39 +0000 UTC
Great teacher, cares a lot about his students, if you don't understand, he'll take time to explain it again. Has a bomb collection of sweaters. As long as you put in effort and show up, you won't fail.MATH2280 2012-11-13 16:07:14 +0000 UTC
Hani is awesome. He has a thick accent. I get that some people are bad with that, but that shouldn't ruin your opinion of him. He explains and to no end, but he's still energetic and interesting. He holds extra office hours and is genuinely concerned about how you're doing. If logic isn't your bag but you need to take it, take it with him!MTHU115 2008-11-16 21:26:07 +0000 UTC
