The worst teacher I ever seen in my life. Offer no help to students. No qualify to be teaching at all. He sucks

THE WORST MOST IMMATURE TEACHER EVER!!

don't ever take his classes, very outdated teaching style, treats his class like they are little kids, if you want to learn anything stay away, if you want an easy easy easy A take his class. Overall empty of any kind of real intelligence.

a guy who shoulda retired 10 yrs ago

he speaks softly like a the voice of a mosquito flying!~ he sucks anywayz!~

terribe, forget about MIT when u take him u will get poor grade/ learn nothing. speaks too softly and scribbles on board tests are EXtremely hard because of this should have retired in 1988!!!

Horrible Horrible professor! Doesn't seem willing to help you when you are in trouble! Always put me down when I went to his office hour!

he has no common sense, he can change his mind anytime which means he can give ur lab an A at 2:00 but give u a C if u let him read the same lab report at 1:50. very whimsical and unstable. tests r ez, yet he's super picky. u may think it's nonsense, but he thinks it's important.

this dude has to teach elementary physcis at LACC. com'on the department please make him retired for giving him free soda.****!

please make him retired...please...

Worst teacher i have ever had in my life (and i've had a lot). He is extremely condescending, even to people that are intelligent (IE not asking stupid questions.) He will find someway to find your faults and just NAIL you for them. His "lectures" are not clear at all. REally, just a bad overall teacher. DO NOT TAKE.

I have to say that he is an easy teacher. However, if you want to survive his class, you need to have strong endurance and perseverance.

Took his online class. Very PICKY. However, very kind and understanding. He is a great professor and he is very smart. Even though he is picky but still Recommend him for sure. Final open notes. have to have 50percent to pass the class.

worst teacher in my life ! that's it.

this teacher is awful!! i dropped the class and signed with JERRY SHI INSTEAD....i took this class online ...he wasnt helpful

Someone please make him go away. Completely unclear and unorganized. Lab grades are entirely dependent on his mood at the time. Forced my group to redo ours 7 times+ before I gave up and left. Makes it feel like you're bothering him if you have a question. NO help. I LOVED physics before his class.

DO NOT TAKE HIS CLASS even if it is the only one left, unless he is the ONLY professor for the class. Extremely picky. Have to label everything and -5 points for 1 missing unit. Lectures are slow and off topic.

ONLINE CLASS. Professor is worthless. He's too picky when you submit an answer and doesn't even give you a tiny bit of partial question. You can write a book for an answer for a question, but if you don't give him exactly what he wants, he will give you zero points for tons of work you do, even if its correct, if its not what he wanted.

This man should no longer be teaching. He may have been a decent professor in the 1950s but now he just stands there sipping his diet coke and going through a lecture at the slowest speed possible. He is very picky with his labs and seems to grade everything based on his mood or probably just at random. I loved physics before this man...

I would rather eat glass than take this class again. There is no teacher more annoying or less helpful anywhere.

This professor is by far the worst I've had at PCC. He is picky as hell with your answers. Rejects your answer for 0 points even if you do deserve credit or you think it's correct. Sometimes I think he's just bored and aggravates you for fun. Haven't learned jack from him and I don't even know how he is still teaching. Truly horrific experience.

he's extremely picky on your work. but you can get a good grade if you do the assignments

This professor is extremely tough and the lecture is very unclear. Half of class dropped. Not recommended.

This professor was extremely frustrating for me. On his tests I would use the correct equation, get the correct answer, and still get a ZERO on the problem because I put a minus sign on the wrong velocity in the starting equation. So over one minus sign I get a zero? Not even partial credit? Don't take this class. He is way too strict and picky!!!

Mundane, repetitive experiments; odd, unfair grading;too picky; cares more about the art than the work done on tests/homework/labs; morbid lecture examples, diagrams,and humor... The physics department at PCC is a joke and is keeping me from transferring.I've gone through Physics 1A, 1B (had to drop - Ms. Quan is hard to understand), now 31A drop:/

The most non-sense and stupid class ever, no material ever provided. Do not expect to learn anything. You will waste your time to post stupid comments and canvas.Sometimes it will took him over 1 week to respond your post, he will argue with u instead of giving credit. Worst online class ever, Not recommended.

STUPID ONLINE CLASS!! lots of "rules" that doesn't make sense. you may wrote a long paragraph but get 0 point. very picky and unorganized class, stay away!!

He is very hard. I recommend taking either Quan or Shi. Lectures are not clear! Help your GPA!!

The instructions were unorganized and lack of quality. His grading system was convoluted and seemed designed to frustrate the participants, his lecture notes more than 3 decades old.

His grading is very particular and almost no partial points if the answer doesn't make him "happy." He doesn't bother to completely check exams or assignments. His philosophy on teaching is little to no lectures. When there are lectures, he demands that students use his "own" proof or definition for exams. A terrible experience in general, avoid!

The online class instructions were the MOST unclear mish-mosh of nonsense I have ever seen. I have taken other online classes with MUCH clearer instructions and I always got As. I don't know what planet this professor comes from but I decided to drop. I'm annoyed! I really wanted to learn about physics but this "class" would just waste my time.

The most picky and unclear professor I have ever taken at PCC. He gives vague lectures then expects you to demonstrate an incredibly detailed understanding of a formula or derivation. A similar story during lab, where you'll spend most of your time just getting his signature to continue to the next step. He grades only on how he feels, beware!

Horrible and vague professor. Unclear with lectures and labs. Most of his lectures are derivation of equations/formulas. Labs instructions are very unclear and we spend most of our time figuring out what to do. But his tests are very very easy. Everything he included on his study guide is exactly in the test. Study the sample test and derivations.

DONT TAKE THIS PROF! Totally unclear grading criteria, grading was inconsistent. There wasn't clear expectations for the class, just general ideas. No assigned textbook, simply told us to "google" and "wikipedia." I didn't learn anything, which is a shame and waste of everyone's time. He shouldn't be allowed to be a professor.

He's very unclear and does not give directions. Especially in an online class, this does not help. Tends to be rude and condescending towards students. Will not give credit if he doesn't "feel" it's right. Lecture notes outdated. Absolutely do not recommend.

His online class was the worst. Did not have a syllabus that is clear to follow. Also, I had to check my grades almost everyday because sometimes he would not even grade my work. Not recommended if your serious about learning physics or passing the class.

No instruction; very much "google it" and do it yourself class. I just don't understand how you expect people, who may have never taken a physics class to just "google" things about physics. There was no structure, except for 3 decade old lecture notes. Sometimes I would complete an "assignment" and have to fight for points. Not worth my time.

Please don't take him. Terrible He is not supposed to be a professor. He has his own world. you won't understand his criteria clearly, and even If you did great on works, he doesn't give you full credits for it. And I don't know why. the worst prof ever. Anyone will be even better than him. he should retire now. DON'T WASTE YOUR TIME

no lenient with grades.

He has lots of extra credit to boost your grade, but the test and all homework assignments are graded harshly.

There is really no criteria for his grading and depends on how he's feeling, so it makes doing homework and taking exams very frustrating. Labs and lectures are pointless, so get ready to learn everything on your own. However, there's a lot of extra credit and if you study the old exams he provides, you should get an A.

Very condescending. Lectures felt more like conversations between him and the people who already knew physics. He would get stuck in the middle of a derivation and say "a miracle occurs" and then write the correct equation. You will be completely lost during labs. Grades exams unfairly. He will not accept any explanation from the textbook.

Do not do it. Your probably looking at the 8% would take again rating thinking can it really be that bad? YES.... Yes he is that bad do not take this class by far most incompetent professor on pccs campus

This guy sets a new bar for how poor a professor can be. The home page has hundreds of unrelated hyperlinks & pictures, and organization that looks like it was done by a 2 year old with crayons. Wanna check your grades? Find which of the 3 grade books is the right one. Want feedback? Doesn't exist. Don't take this class, 77% of the class has an F.

In this class I got the experience of dramatic life ...

If you're reading and we're still quarantined, DON'T TAKE HIM. He is in his 80s and should retire. I took him as an asynchronous class (so no scheduled lecture on zoom, only office hours, and videos) and was offered no support, questions answered with a question, inconsistent directions, and cares more about the format than actual physics.

This class was honestly just awful, truthfully. There were no class meetings so he just gave Youtube lecture videos that were pretty pointless. Labs were difficult with unclear instructions and don't get me started on the format, he way too picky. If you need actually learn physics, take someone else! The bad reviews are there for a reason.

Awful. The only material this professor provides are ancient lecture notes with no actual lecture and a study guide which is basically just a copy of the test, encouraging cheating. Its self paced and self motivated in the sense that you have to independently teach yourself the material without any intervention. No actual teaching is done.

Most unorganized and confusing professor I've ever taken after 7 years of university. No lecture, I studied the textbook, watched all the old lecture videos, and took notes everywhere and somehow I scored the average 60% on the first "quiz". Questions were very vague. Labs are even more confusing. Stay away

Horrible horrible! I was in this professor's class for a month, and it took me about that long to learn his self-made, excel sheet grading system. Grades arbitrarily with no clear rubrics. After you answer discussion posts, he will continue to ask questions, resulting in a grade of 0. Gives grades for jokes, and if he doesn't like them you get a 0.
