I re took this class because he's an **** and got an A with Prof. YOung.

He doesnt explain clearly, grades tests based on answers not work.

Terrible teacher. Hard to understand sometimes because of his accent. Does not grade homework and if you want to know anything he tells you to see him during office hours. A rock as a teacher could have made the class more exciting. Definately do not recommend taking this class with him. Not very hard material but he will do his best to make it hard.

Had for matrix algebra. i read these possts before taking his class and I AM TELLING YOU DO NOT TAKE IT. DO NOT DO NOT DO NOT. i didnt believe them, but BELIEVE THEM. IF NO ONE REGISTERS WE CAN GET THIS **** GONE.

This guy is terrible, he is very hard to follow and he moves so quickly your lost from the start. His tests are insane, you have to know how to solve some of the hardest equations with barely any practice. The homework is long and difficult, he grades harsh and is not helpful at all, so expect to learn on your own and read thoroughly.

He was rude throughout the course and generally un helpful. Would not suggest taking a class with this teacher

I am warning you, I been at RIT for over 3 years now, I never had worse of a professor than this guy. Professor himself is nice, but highly recommend not taking because of difficulty of exam/quiz. Grades so strict and inconsistent. Don't understand most of his lecture because the way he talks. It is enough said.

Ive had my share of tough math teachers, but Ive never experienced such a punitive grader on exams and quizzes. He expects 100% correct, full paragraphs, with absolutely nothing wrong. If you slightly mess up, instantly a 0 for that problem. I studied with him every week, he even convinced me not to withdraw. Worst advice I ever followed.

Lectures are boring and hard to understand. Tests are extremely difficult and you will receive little to no partial credit. Offers no practice exams and waits until the day before the test to post what sections the test will be on. You only have an hour for the tests and you will run out of time to work because of how much content he puts in.

He can switch between being caring, and inconsiderate. He gets visibly frustrated when people cannot recall earlier concepts during lectures. He has no apologies when many people in the class could not finish his exam in time. 3 people managed to, everyone else should've too right? Take his class if you want the most rigorous P&S exp. ever.

Youll probably only end up with him if you get a terrible appointment time like I did. Do anything you can to avoid him. Very few grades and incredibly rapid paced lectures lead to a GPA massacre.

Professor Kumar is awful, avoid this teacher. Currently taking his online Webassign class, and he has no empathy for students during quarantine. He doesn't give nearly enough time for the quizzes, making his class overly stressful, because he expects you to have perfect work. His lecturing style is confusing as he jumps from problem to problem.

Oh dear god where do I begin. I hate this man, especially with this semester being Zoom based. He takes attendance, however this doesn't count towards your grade at all. His lectures are very dry, and all of the homework is from the textbook and he steals quiz problems from the book and other schools. He never answers emails. 0/10 don't recommend.

Do yourself a favor and never take one of his classes. I don't know if its because it has been zoom based and he isn't quite sure how to teach in this format, but he is by far one of the worst professors I've had at RIT. He takes ridiculous points off for every quiz/exam, is quite rude and has an attitude towards students, and has NO empathy

By far one of the most strictest professors in terms of grading, will literally cut off points for the silliest of mistakes. Avoid at all cost.

I would never recommend Kumar as a prof, by far one of the worst I've had. His lectures are hard to follow and he will take off so many points for the most minor mistakes. He is available for office hours which is great, but he can be very condescending and rude when you ask for help. He simply told me to "practice more" rather than helping.

Please listen to the other reviews and never take classes from this guy. I have never failed or dropped a course before until now. Prof. Kumar's lectures are terrible online, and his grading policy is awful. Tests are worth 85% of your grade (with no makeups or extra credit), and is a very strict grader. He doesn't believe in partial credit.

I've never written a review for a professor until now. He is an extremely tough grader and will deduct all points if the problem is solved differently than his method. If you do not use his format to perfection, even if you get the correct answer, you still get a zero. His quizzes are mostly one question, so you have no chance for partial credit.

One of the worst professors at RIT. Do yourself a favor and do not take him. His exams and quizzes press you for time and is a petty and anal grader. Do not even take him even if his section is the only one available, the better choice would be to drop it that semester. I worked really hard at this class, did lectures, still got a bad grade

Honestly the worst professor I've ever had. Did not help me to learn this course at all. Go with someone else if you can, don't waste your time and money with this professor.

Terrible professor that doesn't give enough time for quizzes. Many people had an issue with just 10 minutes and another 10 for submitting a pdf.

The worst teacher Ive ever had in my life, lectures in hieroglyphics because his handwriting is terrible. Gives 10 minute quizzes that are impossible to complete in that time. The strictest grader I have ever seen, takes points off for even the slightest mistake. Please never take, to save you time and stress

I read the reviews for this professor. I thought to myself "I'm good at math. It won't matter that he's a tough grader, I got this." He's worse than just a tough grader. This is the worst professor I've had at RIT, and I've had some bad ones. He talks from the start of class to the end of class with no class interaction. DO NOT TAKE THIS PROF!

Do not take any class with Kumar. Kumar should not be allowed to teach. I dont know how else to say he is a terrible professor, do not take him. If there were a list of worst people/profs Kumar would be too 2 and not 2. I have never seen any prof casually watch half the class get a 40 on an exam and proceed as if everything is normal.

Professor Kumar is one of the worst lecturers I have ever had at RIT, he was never clear on what topic we were talking about, or what we were doing. He just started writing and if you could easily fall behind, especially since he writes quickly and never explains afterwards and his handwriting is impossible to read. Also the grade was 90% tests.

Honestly the worst professor I have ever had at RIT. Guy has boring 1 hour 45-minute lectures that are impossible to keep up with. Grade rests almost entirely on exams. This wouldn't be the worst on its own, but the exams are almost impossible to pass. Only 1, singular, measly student got an A, with the average being 50%. How am I supposed to pass?

Worst professor by far that I've had here. While he's not horrible with the actual lectures, his quizzes and tests are just unfair. They are pretty unrelated to classwork, so you need to read the textbook to have a shot at doing well. Currently, class average is a 65 and he blames it on the class for not studying

It's good that Kumar doesn't teach freshman-level courses because some first years might not be 18 and his teaching could be considered child abuse. Do not take Kumar for linear algebra or any class. I like to think math came easy to me he showed me that 30/100 on exams are the only thing that comes easy to me. DO. NOT. TAKE. KUMAR.

Kumar has to be the worst professor I've ever had. His desire for you to understand the concepts on a fundamental level is admirable however he expects you to achieve that on your own. he will introduce the concept and a extremely basic example which pale in comparison to the exam and quiz questions. He also rushes through lectures.

Responds to questions with "I already explained this" Docked points from my midterm for writing "X: _" instead of "Let X be _" Only reason I got B+ is bc I'd already taken 4 stat classes and knew most of the material I had to tutor peers on his ENGLISH USAGE bc he deliberately wrote confusing questions that had no place in a stats exam DO NOT TAKE!

There is no extra credit or quiz make-ups. If you miss a class, there is no way to make it up. The final was the hardest test I've ever taken. Quizzes and tests are taken at the end of the class time, with an hour lecture first (on things that are not on the test). He occasionally made simple algebraic errors that students had to correct.

Absolutely awful. He is the worst teacher in the entire department by far. There was a situation where the class average on a test was a 40%, and he REFUSES to curve anything. Every time students as a whole do poorly on an exam, he blames the students for not studying enough rather than the fact that his grading is completely absurd. 0/10 :(

This guy was the worst professor I have had in my life. If you have the chance avoid him at ALL COSTS. Tests are extremely difficult and his grading is completely nonsesne. First and Last exams I failed due to little to NO points on questions that were in my opinion worthy of some partial credit. My GPA was 3.7 before his class and i barely passed.

AVOID AVOID AVOID AVOID DO NOT TAKE KUMAR IF YOU CAN

Terrible teacher. Does not understand how to grade or give enough time for exams or quizzes. Made mistakes during lectures which someone who claims to have a PHD should not make trivial mistakes. Left the class with less brain cells than when it started.

Does not know how to assign problems that truly test student comprehension. More focused on how fast can students solve problems and write paragraphs. Did not give ANY partial credit.

The professor was a harsh grader and there was a quiz almost every week. If you miss a quiz, there was no way to make it up. Kumar blames the failing grades on under preparation. I would consider myself good at math but this class was so difficult.

He structures the class in a dysfunctional way. He has no graded homework, only quizzes and exams, which are insanely difficult with low averages. It feels like you are drowning when you are on average doing well on the exam. He prefers difficult theoretical problems making the course work impossible to understand.

Please listen to the reviews and do not take this professor, even if his is the only section that works for you. While the material itself is not very difficult, his expectations and range of questions on three (3) tests, which are still 85% of your grade, are impossible to satisfy. Horrible teaching style, no partial credit. Heed my warning.
