HORRIBLE!!!

Smart guy, but is completely clueless when it comes to teaching. Grades inconsistantly, and seemingly unaware that nobody in class has any idea what he's lecturing about.

Very hard to understand, doesn't explain. Just reteaches examples from the book. Failed the midterm & final, but he passed me.

Enjoys making you miserable on the tests. He tests on stuff that wasn't even discussed in class!I did every single math homework math problem and still struggled, and so did the rest of my group.

I think the computer program in MATH 015, ALEKS is better than this prof. with all respects. He doesn't explain clearly. He tries to do he's own thing instead of just explaining it from the book.

Did not really seem like he knew wat was going on. And always was sweating like he was scared of teaching the class. I did not think he was that good of a teacher because he thought the class was at a good spot with a 65% average. And now my uncle does not think I appreciate him paying my tuitiona nd i have to retake that class.

Had no clue how to teach, made MANY mistakes in examples. Overall very unhelpful in office hours. Take your class with another teacher.

If you get this professor, I suggest getting a different one. He goes through the material very fast, teaches straight from the book, doesn't really go over too many HW problems, the stuff on the tests, some of it we never went through in class.

DO NOT REGISTER FOR HIS CLASS!!! He yelled at a student for sharpening his pencil during class. Volatile personality! Lacking in character, rude, and sweats excessively. I could barley understand him. Social inept! Lacks communication skills which are key in teaching.The worst instructor that I've ever had. Less than helpful during office hours.

Made me hate math and Cal State. Run in the other direction and don't look back! Unless you are a math genius, I don't recommend this professor.

He is the worst professor ever, i suggest you find another math class. You have quizzes every day so being absent isn't an option and he grades so rediculous. If you don't word exactly the way he wants he marks you off a ton. Hard only because he makes it hard not because the math is hard.

IM TELLING YOU NOW!....DONT DO IT TO YOURSELF! IF YOU HAVE ANY OTHER OPTION FOR A TEACHER, EVEN ONLINE..DO IT. I COULD HAVE TAUGHT MYSELF THIS CRAP BETTER!!!

This teacher is HORRIBLE!!!!! worst accident ever, does not like helping students, teachers fast. DO NOT take him

The worst teacher I've EVER had. NO joke. Don't just get this guy because you like what time his class is at. I have never failed a class before until this one. His lectures are miserably boring and he grades super hard. The first thing he said to us was the class average for my first exam is usually a 58%. DON'T GET HIM!!!

He is probably the worst teacher I've ever had. Makes countless mistakes and recites the book word-for-word. For $2000 I would have liked a little more. Oh well, I can take comfort in the fact that I make more $ then him and don't have to hide behind the walls of academia ;) AVOID HIM AT ALL COSTS, SWITCH SCHOOLS IF NEEDED!!! SERIOUSLY!!!

BEWARE!!! WORST TEACHER EVER, GRADES HOMEWORK HARSHLY, NO STUDY GUIDES FOR TESTS, LIKES TO PUT ?'s ALL OVER YOUR TESTS AND HOMEWORKS. EXAMPLES ON BOARD COME STRAIT FROM THE BOOK, IF HE DOES NOT FINISH THE LECTURE HE TELLS YOU TO FIGURE IT OUT ON YOUR OWN. DO NOT TAKE THIS CLASS, GO ELSE WHERE, SAVE YOURSELF A SEMESTER AND A BAD GRADE!!!!

RUN! You have been warned...

The class is solely based off of tests. Has an accent so hard to understand at times. Says, "So in other words" and that he's always right a lot. I don't recommend because it is easy material but he makes it more difficult than it is.

HATE THIS CLASS, i feel like im on a sinking ship and i cnt get off. I not a dumb person and the material isn't hard he just makes it so easy to fail his class, and makes the tests impossible you cn only miss like 4 ..its mutiple choice with no parial points so its easy to second guess your self and mess up. Only plus side homework is graded.

Although generally he is kind of nice, he is by far the worst professor I've ever had. The material isn't difficult, but he makes it more complicated than it is. I pretty much had to teach myself. Good luck getting all the examples he shows on the board too. Before you're even done writing them down, he erases them. Try to avoid this class.

If you don't want an F or a D in as a grade then don't take this class. PLEASE. I don't even know why he's still teaching. RUN please RUN. I got my first D of all time because of him.

Very hard to understand his accent. Drop this class if you get him. He doesn't care for attendance and I barely used the books. He assigns homework but it's really pointless. The most helpful thing I found was to study the sample tests and go to the math lab for help. Memorize his sample tests for the actual test and you'll pass the class.

Nice guy but impossible teacher. Subtracts points for everything even and for getting the right answer but not doing it his way. Lots of homework 20+ hours per week. Don't take a class with him.

Does not let students think outside the box when solving problems. If you do not do it word for word his way you are doing it wrong. Even if you get the correct answer. Avoid at all cost.

He is super hard! He reads right from the textbook and doesn't really know what he's doing. Thick Chinese accent so he's hard to understand. You have an individual quiz each Tuesday, and a group quiz each Thursday so you pretty much always need to go to class

Professor Chien was an extremely difficult teacher. I spent many hours in the math lab because he would only teach the examples that the text gave but when it came to the homework problems, I was at a loss because he didn't elaborate on much. It is possible to pass but you MUST put in effort and he likes to see that you care.

Worst professor I've had at cal state! If you struggle math to begin with then DO NOT take this class. He just goes by the examples in the book and erases the board before you could even copy it down. If you read everyone else's comments they're practically saying the same thing so don't waste your time with his class if you can help it!

I would not recommend anyone to take this class, even if you know calculus. Worst professor I have taken in my 5 years of college at a uni.

This professor sucks, lectures are useless, he makes the material more difficult than it has to be it's kind of absurd, he doesn't post written HW online, so u have to go to class. The grading scale is very test heavy so there's minimal room for error, it's pretty stressful. Written and online hw. Best bet is to study hw solutions for exam.

By far the worst professor I have had at this school. Students had a 40% test average on both midterms, which are the bulk of your grade. The final is brutal. The homework is not difficult but your grade is determined by the exams. AVOID AT ALL COSTS

This professor really sucks!! This is the worst professor I have had. His tests and final are ridiculous difficult. The entire class is lecture but all his lectures are useless. He makes the class to look difficult. Homework and exams are totally different. Almost a third/fourth of the class failed it. AVOID HIM!!!

DO NOT take this class. He knows the material but his lectures are all over the place. You end up having to teach yourself from the book.

He is a nice guy, and honestly funny. His class is extremely hard and he doesn't explain the problems he is doing. The test questions are straight from the homework. His grading is unreasonable and unfair. He does not curve test but he does curve your grade slightly. Beware of him because most students do not pass his classes.

His teaching skills are very poor. Lectures are from the book, but he teaches worse than the book. Memorizing the homework is the way to pass his tests. Must write complete sentences for the answer. It's not that he's hard, but his poor teaching ability makes him difficult to understand. In the end, I'm not taking another class with him.

Professor Chien actively works against the student's grades with his very lengthy and very time-constrained tests, and also doesn't curve. His lectures are often very confusing, and goes strictly by the book, but never explains any theorems or definitions further but expects us to understand. I hope I never have to take a class with him again.

I consider myself a fairly intelligent individual, and I usually ENJOY math courses, which I know is unusual... But this professor has been THE WORST I HAVE ENCOUNTERED (and I'm writing this as I graduate). He should not be allowed to teach Linear Algebra. He'll grade your tests like they're English papers, and stress you out WAYYYY too much. AVOID

I started taking this course despite recommendations from friends to drop him. His lectures contribute nothing to the students understanding of the material. Exams used random questions and his response to low averages was to assign more homework instead of student feedback (ex: recorded lectures) which he deemed too hard for him to implement.

This professor is TERRIBLE. The exams are 90% of the grade he does not curve or give any bonus points or give a study guide. He is not good at teaching and his lectures make little to no sense. At the very last second he made the grade to get a C about 50%, but many people after the first exam, stopped paying attention as they had no way to pass.

Math 342 wasn't listed, but the class was unnecessarily hard. Tests were so heavily weighted that if you did poorly on one there was no chance of recovery. The main reason my classmates and I passed the class is because he lowered the passing grade to 50%. The lectures felt pointless as he read from the textbook. Avoid this professor if you can.

Dude failed me. Not a man of his word. L professor with a super thick accent.

WORST PROFESSOR I've ever taken. This class was my hardest class I've ever taken and his grading system was outrageous. He knocks down so may points for everything. AVOID him at all costs.

FOR CALC II Do not take professor Chien. Very hard to understand him and he talks all class long. Quizzes are taken at the end of every class, but he drops your worst 4 (but can't make them up). Uses web assign for weekly hw.

Dr. Chien yelled at a 16 year old student in a 400-level math class. He was upset that the student didn't understand the material. How does Dr. Chien have the audacity or courage to do that? It's so impressive that a 16 year old is there, but Dr. Chien doesn't even care. He doesn't show bias or favoritism for or against students, but this is wrong.
