Attendance not mandatory. Go to all the recitations and do all of the weekly assignments. Those points really add up. I went to all of three classes this semester- you can barely understand what he is saying. Take notes off his slides and be familiar with the material and you'll do ok. Exams are tricky, final was surprisingly easier then the exams.

His class can be said to be the simplest. homework depends on self-consciousness as long as you finish it daily. The first three mid-term exams were all questions after the textbook. Although final is a bit difficult, if the previous chapters have a good foundation, final will not become very bad.

Do not take Differential Equations with this professor. Has weekly quizzes that are averaged at the end of the semester. Has three midterms, and a final. Midterms aren't too bad if you study, final was ok. If you put the time to study outside of class the topics, you should be fine with the course. Lies about grading midterms, took a month to grade

Matlab homework is very easy and basically free points, and lectures are organized and well taught. That being said, he takes forever to grade his exams, which is frustrating. He is also way more conceptual than other lin alg professors, so his exams and quizzes are harder.

Lectures were a repeat of the textbook almost word for word. Very little explanation or examples. Took very very long to grade anything. At any cost take this course with a different professor. Test difficulty varied greatly, incorrectly grading most students' tests. Good luck getting in contact with him outside of class

Professor Goonetilleke really did a good job explaining material. Homework and exams were fair. I enjoyed him as a professor but he took FOREVER to grade exams. Each exam took over a month to get back, and we would be taking another exam before seeing the previous one's grade. We took the final a week ago and still don't have our grades for exam 3.

He was the best math lecturer I've ever had; he made Lin Al interesting and fun. Test are easy, study guide prep you well. Attendance isn't mandatory but if you want a good grade it is. Quizes are hard and will bring down your grade a little. Test take months to grade. I just received my Exam 3 and Final grades yesterday

This is the best Linear Algebra professor you could take. He truly understands linear algebra concepts and tries his best to get you to understand them. He is a great professor and a very cool guy, although he does take a while to grade.Your final grade is mostly based on 3 midterms + final. He is also willing to work with you to improve your grade

Great prof. C4 was pretty easy overall and he made his exams pretty easy too. His lectures are great but you don't NEED to go to class to do well in his class. The material for the most parts follows the slides he uploads and can be self taught thru textbooks. If u wanna do well in his class just do a couple practice problems after each day.

I took him for Calc 244 and he is genuinely one of the best professors I have had so far. All of his test material is directly from lecture so I recommend going to them. He does take a while to grade the exams and the recitations quizzes can be hard but he prepares you well for them.

Posting this review before any grades have been assigned. This professor is the most uninspiring teacher I have had at Rutgers. He reads straight from the textbook and makes many mistakes per lecture, often relying on students to correct his mistakes. He is unable to deliver big-picture insights. Steer clear if you are looking to learn!

I loved Professor Goonetilleke. He was just amazing, he taught Linear Algebra in a way that was very easy to understand. Whenever I had extenuating circumstances that came about because of life, work, or whatever, he was always understanding, and almost always granted me extensions. Possibly the nicest Professor at Rutgers.

Really easy class. His lectures were pretty helpful but if you don't wanna show up you can just self-learn the material. You learn basically no theory and he'll actively avoid explaining any theory. It's a computational class and the final is basically all computations and remembering specific things.

Easily one of the most disorganized + confusing professors I've ever had. Does not explain content concisely or clearly, slides are copy pasted from the textbook + not easily understandable for someone new to the material (many unfixed formatting errors too). Class frequently corrects his mistakes. Takes month+ for grades. Extremely lazy professor.

He's an extremely kind and caring dude with EXTREMELY straight forward open ended portions for exams. The multiple-choice gets tricky, but studying the slides he uploads provides sufficient practice. Extremely accessible in office hours and understanding of external circumstances. Only flaw is slow grading due to terrible TA's.

Great professor that explains everything well. Could tell he cares about his students and will make time for you especially in office hours. Does grade a little slow but his exams are all very straight forward and are fairly easy as long as you do the review. Most people shouldn't have trouble with this class. I had a tough schedule and I was fine

He was a good professor. Explained the topics very well, but handwriting can sometimes be sloppy. The homework can be tedious and requires a lot of work, but it is doable. The exams were fair: open-ended was easy, but MCQ can be tricky. Fortunately, he gets the MCQ from the textbook and previous midterms. Pay attention in class, and you'll do well.

He's a very nice person and not the worst professor, but it depends on your preferred teaching style. Some people found his lectures helpful, I didn't.
