horrible teacher that is not at all helpful or considerate. Thinks everybody slacks off when he can't really teach himself. doesn't curve

Discrete math is a hard subject, but he makes it ten times harder, I dropped with about half the class. Mind you, he may be your only option, but avoid him if you can.

Do not take this class. Dr. Kustin is probably a nice guy but is not a very good teacher. If you want an A be sure you took BC Calculus in high school. Tests are amazingly difficult and it is almost impossible to follow his lectures. Is not very kind with grading and doesn't give out a lot of partial credit. Good Luck if you are taking this class.

Gave me my first failing grade in my entire life. He has poor social skills so its hard to ask him one on one questions. Will not work with you and will fail you and not think twice about it. This is by far the worst teach i have ever taking!!!

I do have 2 agree with the situation that much of what the teacher teaches is unclear. I took the class in Summer & it was really horrible. I study 10 hours every day & I don't that much progress. I find it difficult to learn these concepts when it feels like I need to memorize many of the proofs just to get decent grades on these tests. avoid him

HORRIBLE!!!! He is goes so quickly and gets mad when you ask a question. He gives one quiz a week with one question, so if you get it wrong you get a zero. He even said himself that it is extremely difficult to survive his class. DONT TAKE IT!!!!!!

Absolutely the worst professor I have ever had. I would not be surprised if this man had Aspergers. By the final there were 7 people in a previously 30 person class

This professor is AWFUL. He could make simple addition seem difficult. It's obvious he is a very intelligent man, but he is a terrible teacher. He chooses the most difficult problems for tests and doesn't curve at all! Avoid him at all costs!

DO NOT TAKE! At first he seemed nice & helpful, but ended being extremely hard. Is not helpful at all, philosophy is you either know it or don't. 1/2 class dropped, the remaining 1/2 still failed. Doesn't answer questions in class b/c he goes off in his own calc world. If you even deviate from the right answer slightly, he will mark it all wrong

STAY AWAY. literally worst professor in the whole school. no amount of studying will prepare you for his tests. he gives no partial credit even for trivial mistakes(mixed up negative signs and such). He is rude to students who ask questions and leaves insults on your tests when you inevitably get something wrong. avoid at all costs.

While he seems like a nice man in lecture, he has an impossible grading style and gives little to no partial credit. He also leaves rude comments on student's quizzes. I highly recommend avoiding his section at all costs. HE ONLY PASSED 6 PEOPLE LAST SEMESTER LIKE WHAT

Kustin is very smart but a horrible teacher. He takes a difficult course and makes it impossible by giving extremely hard questions on his tests, and by handing out little to no partial credit on incorrect answers.

He is all over the place in his lectures and talks to himself.

He is probably the worst teacher I have ever had at USC. He expects you to know everything he is talking about and scolds you for not. I have studied for hours upon hours and still struggled immensely on his tests. He did not offer office hours when I asked and suggested that I drop the class instead of wanting to help me.

By far the worst professor I've had. He doesn't care if you pass. He only cares that he went over the sections as quickly as possible. And questions are ignored

Genuinely a nice person who memorizes students' names and gives feedback on every quiz, but has the worst lectures and teaching style of any teacher. Avoid taking from him. Get ready to learn from YouTube lectures.

Prof Kustin is very confusing and does not do a good job of teaching. He expects students to know a lot of things that I did not know coming into the class. He also does not explain any methods or processes, just does problems during class. There is a quiz every class and tests are only 5-7 problems, but very tricky. DO NOT TAKE THIS CLASS!!!!!

Stood up at the board and did a few examples while he talked to himself the entire class every class. impossible to understand even if he did speak clearly. very rude if you don't understand what he is doing and doesn't give partial credit. BUT if you fail everything and make an A on the final you get an A or B in the class. (thank god for chegg)

This class tests your ability on memorization. Why show up when the web can teach you just as well minus the sass. Yeah the problems are easy for you Kustin. You've been doing the same problems for 92 years. Thank you. Save yourselves.

I found him to be horribly rude, dismissive, and demeaning. I'v never had such a bad experience with a professor on a personal level before. He does post great online resources for students to review before quizzes and exams.

He's literally the worst prof I've had. He doesn't respect his students, he rarely ever answers your questions and when he does it's not helpful. He gives incredibly unreasonable tests and quizzes and barely teaches anything. I probably would've gotten the same grade if I wouldn't have gone to class. Do NOT take him.

It was a very difficult class which was made even harder by his tough grading and weird teaching style. He is very unclear on what he wants and expects out of students, and is very strict on his partial credit. He gives lots of quizzes and a few test but your final grade is determined off of the final exam. It can save or fail you.

STOP. DONT EVEN THINK ABOUT THIS. Lectures are all over the place and he often makes mistakes and fails to completely to explain topics. Expects you to be an expert in every topic and rule prior to this point. Save your grade forgiveness, everything weighted off the final exam. Dont. take it during the summer if you have to. focus on old finals

Never take him unless you want a semester full of unnecessary stress.

I was hopeful that this would be my 4th and final semester of math, but now I'm not sure I'll pass. Terrible at teaching, knows everything and is rude to those who don't. Will make you know the hardest problems and I hope you aced Calc 2,haha, cuz you'll need it. Avoid at all costs, unless you can cram like crazy and pull it off.

Awful teacher, doesnt answer questions and gets mad when you dont know what is going on. Very rude and has not been helpful. Do not take him.

Five question exams with hardly any partial credit. He is also not respectful towards students. He's an ok teacher, but a very tough grader. I would not recommend him.

He never entered grades. If you asked him about your grades, he would either be rude or respond with a bunch of random numbers with no context. He was rude to people who asked questions in class, and I literally never learned a single thing from the class. The only reason I got an A is because I looked up the material and studied before tests.

This teacher, for a lack of a better term, sucks. I've never had a teacher so awful. Would never go over any examples in class and head straight to proofs. Boring class. He was so bad that he made me switch my major. The only thing going for him is that he has a fun personality. Also doesn't believe in partial credit. Grades tests pretty hard.

Worst professor ever, very rude and unprofessional with student when they have any questions about his material.

DO NOT TAKE THIS PROFESSOR. I got a F in this class because he does not teach, constantly trips over himself (physically and mentally). I had life scholarship that is long gone. University messed me over too as I had to take orientation before I could register for classes. This orientation was 4 DAYS BEFORE CLASSES STARTED. Had no other choice.

Only teaches the basics of each topic, and expects you to learn it on your own. Gives quizzes once a week with one question, and gives very little partial credit. Gives feedback on quizzes, but is very rude about it if you did not understand the material.

weekly quizzes and grades everything vary harshly. zero partial credit. i completely understand the topic and messed up on one negative sign because quizzes are time limited and got a 0. messes up on many examples and instructions given are unclear. only way to pass the class is youtube or tutors.

terrible

lectures are extremely unclear, teaches only theory, if he does give an example he messes it up, left with more questions than answers, zero partial credit. studied over 15 hours for exam and he took off 60 points for not showing every single step of my work, i clearly had the basis written out, made a 34. dropping class right now.

He only teaches theory (because that's what he knows how to do) and doesn't answer questions if he doesn't know how to. He grades harshly and there's little to know partial credit. He's terrible. Just don't take him, I'm passing but I would not want to take him ever again.

Overall is a very difficult man to reason with. Gets sidetracked and lost in narration when lecturing so they are not even worth going to, just teach yourself the material or find a different professor. You don't want to see him throw erasers across the room when he gets lost teaching. Or mad at a student for asking a basic question.

Would not recommend this class because the professor is very rude to students, gives no partial credit for anything, really only teaches theory with very few examples, and gets lost while doing problems even though he is mainly copying down already worked out problems. If you do take this class, be prepared to learn it on your own.

I had him for M544 and M546 and he is the worst lecturer and rudest prof. The grade is determined by 8 hw quizzes and 4 tests. His 5-7 question tests are not reflected by what he teaches. DO EVERY OLD TEST FROM HIS PAST YEARS to prepare and then you have a fighting chance. He curves at the end, so don't panic if you fail a test.

Not a professor I would ever want to take again. Must be perfect on every answer on exams with no partial credit. I did poorly on an exam I thought I aced and when I received it, just because of a missed sign at the end of a problem led to missing all points on that problem. Went to office hours, I got no help and he was very rude to me.

Terrible Professor, MUST be perfect on every question on exams. No partial credit on questions, did not teach me anything. Bad lectures, bad everything. After one of his exams I went to his office hours to get help on understanding why I got the score that I did on my exam. He just was cussing at me and did not help me at all.

Genuinely unbelievable. This guy is 80 years old, can barely walk, hunches over the board and writes in a way that no students can see, while muttering to himself with no clear lesson plan, then forces a quiz on students EVERY CLASS, giving no more than 10 minutes. He offers no partial credit, no extra credit, and no clear way to pass.

This professor made last semester the worst 4.5 months of my life. Literally contemplated suicide because of him. He's old, miserable, and honestly, I doubt he wants anybody to pass. In fact, I feel like he's purposely trying to make student fail. He's practically gatekeeping this subject. He won't help at all during office hours. PICK ANOTHER PROF

ANDY teaches this class bc he can't teach
