Comment:
Really great professor! He teaches backwards in the way Calc 4 is to be taught, which was a smart move. We use Laplace transform for EVERYTHING, so pay attention! Taking good notes, doing the webassign hw genuinely and attending SI is a ticket to a good grade. He will help you if you ask, so take advantage! Be sure to study up well.

He is super caring and helpful, and very sweet! I've been in his class and his SI for MATH 204 and he's always been very enthusiastic and kind. His group project is a mess; however, he was always helpful when I had questions about it and guided me through the whole thing. No textbook, just webassign. Exams reflective of homework, how I did well

Comment:
One of my favorite professors in this school. Really kind and approachable outside of class, and it's obvious that he cares about the students and their success. There is quite a bit of homework, but it is really relevant to the exams and quizzes. If you do the homework and actually understand it, you won't have any problems getting a good grade.

Professor Hayrapetyan is Awesome! Abstract Algebra is very difficult, but he does a great job explaining the material and the problem solving mindset required. His quizzes and tests are very difficult, but he is extremely fair. He is very approachable with questions, and patient with explaining difficult concepts if you are confused.

He is a great professor. Many people talk bad about him, but if you just show up and do the homework you'll do great. He's a fun guy and is always very willing to help outside if class.

He's a funny character but he doesn't go easy with the class content. Definitely do the homework, if you don't you are not gonna pass and that is where he pulls his test problems from. He cares a lot so if you do badly on a test he's gonna scold you but he just wants everyone to understand the class.

Comment:
"I am very disappointed with all of your test scores. I am not sure why you had a problem with it. I have no comments for you." He says to the class. Not sure why we all are doing poorly... hmm... Lectures drag on forever, and just writes on the board and narrates it. Teach yourself and you might pass.

Comment:
Do you know matlab? If you said no then you're about to sit on a rollercoaster. Lots of complicated matlab with 0 instruction; even a test in Matlab where you have to code AND write it down on paper. If you do the homework, you'll pass.. Just keep chugging through the matlab. Talk to him, he's personable. Wrong answer, right process? 50% GOTOCLASS

His class has an outrageous amount of homework for the amount of material covered. There are homework and matlab assignments due every week. The normal coursework is pretty well taught and easy to understand, however he expects you to know how to code in matlab, without teaching you any coding.

Overall good prof, kind of hard to understand, and often found better ways to do things than how he explained them, but he's an easy grader and curves the class. Also has an especially small class so we were able to relax a little and have fun with it. I struggle with math, but I got through it respectably.

This course is HARD. The homework is difficult, go to his office and ask lots of questions. The tests are 50% memorization of definitions and 50% questions usually modified from homework by changing numbers. If there is a homework question which uses a variable, he will often put a number in place of the variable and use that question.

Ruben is the best professor at Kettering. He is hilarious, cares about students, and loves his job. This course is hard. The concepts are abstract and require a lot of work. Do the homework he assigns, ask lots of questions, and go to office hours. Tests are hard, but based on homework. Do homework --- Get A

Comment:
I don't know why Hayrapetyan has a good rating on here. Worst teacher I had at Kettering. He curves quite a bit but has no grading scale in his rubric so you don't know what grade you have until finals are posted. Unclear during the lectures and I had to google a majority of the homework problems.

Excellent professor. He would spend about an hour every class period answering questions about homework. He takes the class at whatever speed is manageable for the students. Quizzes come directly from homework but tests are very difficult.

Ruben is that rare kind of professor that can bring joy to an entire term. Inspired, loves his material, loves teaching this course, patient when needed, but in-depth when appropriate. Cheerful, pleasant disposition. Homework is there, but never overwhelming. Tests are spaced pleasantly, and you know what you're getting into. Top tier math prof.

Very complex exams and doesnt convey the material in a manner that can be understood. All he does is say what he's writing on the board and that's all.

What can I say, my favorite teacher this far at Kettering!! I actually look forward to going to his class. He has a very structured class, and material you are quizzed on comes straight from the homework. He is super approachable and such a good guy, he wants you to learn and do well. Wish I could have him for every one of my math classes!! :)

You will have homework that will be graded, but he is very flexible about helping his students. Do not be afraid of asking his help. On tests, if you turn it in early, he will look at it, tell you if you have made a mistake on it, and let you correct it. He also has a very low fail percentage, so you may be doing better than you think.

Definitely my favorite professor here at Kettering. He gets off topic from time to time, but he can be pretty hilarious. Took him for Calc 2 and Diff Eq, can't wait until he's teaching Matrix Algebra.
