MEAN GUY!!!!! MAKES CHEM HARD!! DO NOT TAKE HIS CLASS! LAZY TOO

Horrable teacher. Will intentionally argue and yell at his students, will dissapear for an hour at a time during lab, and makes all the material over complicated.

A totall NIGHTMARE. He doesn't teach anything, it's as though he's talking to himself when he's lecturin. He's tests are just outta this world. DO NOT TAKE HIM. Take Yolles instead.

bad teacher and doesn't have mercy! he doesn't like to re-explain the material, instead he would make you feel lower!

i wonder wht type of teacher he is.murmurs in class.but exam ok as long as u look at the past paper he post.tht helps a lot.call us to do HW and lab for nothing.never grade.waste time.i think he should teach high school. sorry Mr TONG.take gray/fisher.

his lectures have no beginning and end. he will teach the class like everyone knows chemistry. when you ask him to clarify concepts, he does so in a scattered condescending way, making you not want to ask any more questions again.

Tong is unclear and does not make himself available to answer students questions. if you question something he will vere off in a different direction and confuse you even more. chem is hard no matter what, but support from the teacher is necessary.

doesn't explain well, he thinks you already know how to solve every problem. If you ask a question from the book, he dissagrees with the book, and says he is right.

This professor compared to earlier professors I've had is very unorganized. You never really know when assignments are due sometimes. This is one of those classes where you can get lost in easily because the lectures are not helpful.

very unclear, doesn't help w. questions, takes pointes 4 doing more work than required on exams, makes ppl in class feel stupid for asking anything, finds hardest uncovered stuff and puts on exams. take any1 but him!! 64 ppl agree he sux bad!!

HE IS THE WORST TEACHER ON CAMPUS. I NEVER LEARNT ANYTHING IN GEN CHEM COZ OF HIS TEACHING. HE NEVER TAUGHT ANYTHING. HE IS VERY SELF ABSORBED DURING HIS LECTURES. HE GETS OFFENDED AND YELLS IF WE ASK QUES. EVEN IF U CAN TEACH URSELF CHEM, ITS STILL BAD

He's not the worse teacher but he's pretty bad and by that I mean NOT GOOD. His only talent is having the ability to make you feel stupid if you ever ask him a question. His second talent is confusing you even more.

DON'T TAKE HIM!!! UNLESS YOU'RE A SQUARE.

I'd rather get my teeth pulled than take another course from this teacher. The government should give him a restraining order from any teaching situations.

He's only a 3 for ease b/c if he doesn't have time to grade ur test, he assumes full credit on whatever he didn't get to. But the tests always has some inane ques. that he covered for two min in some lecture at the beginning of the quarter.

he is very hard to follow in his lectures. tests are very hard. I do not recommend him.

Tong was one of the worst teachers I have ever had. I have my bachelor's degree in education so I have some idea what techniques are useful, not to mention extensive experience in college. If you can avoid him, do it.

Tong is a miserable man.He critizes students if they ask q's.He assigns hw assignments BEFORE he evens teaches it. He expects you to KNOW your stuff. Exams are pretty easy if you STUDY,exams are long. so much to do and SO LITTLE TIME. I can barely finish on time. All he does is COMPLAIN. UNORGANIZED

Tong doesn't know what he's doing...his lectures are confusing, he writes all over the board making a mess and makes the student try to figure out what he just wrote. Questions asked are responded with an insults or he tells you that you should have been paying attention. If Tong is the only time

Not helpful at all. The reason most people get good grades or pass his class is that he has past exams up all the time. Its all in doing it yourself, don't ask him for anything.

Wow!!! Worst teacher I have had in a while, he didn't teach me one thing...although I am going to get an A for his class its all because I studied from the freaking book. Through the whole quater he only gave me one straight answer, the rest was full of $h!t

my god! so true...take his class and it's all independent study..don't even bother coming to his lecture lab...stay home and read the book instead...see his previous exams posted on the window..know wat he expected and study...not hard..but if u dont study, dont expected a high grade.

went to first lecture. already, i counted 27errors in 1 of his lecture. I will enjoy this guy because i won't have to attend lecture and learn this**** on my own. Dr Muzzi totally prepared me for this guy's easiness. Time to learn this thing at MY RATE!!!

You won't learn anything, seriously. He's a nice guy and if you kiss his butt, he'll cut you only a LITTLE BIT of slack. He's kind of annoying and his lectures are hard to understand sometimes.

SUX SUX SUX!!!! DON'T TAKE HIM! only he wud understand wat he's saying...he's a nice guy, no doubt, but a bad teacher...

holy mary mother of jesus, homer tong is such a bad instructor. does he even read the current edition of the text? does he even know he is suppose to teach us organic chemistry? if you want to learn chemistry, take someone else. if you want to join the circus, take tong's class.

Worst teacher I've ever encountered! He doesn't grade very hard, but you'll definitely leave without learning ANYTHING. I had to learn everything on my own by reading the textbook. he's unclear, unhelpful, AND worst of all condescending to students. He always acts superior and sometimes is very mean-spirited in his comments.

Totally terrible

He's impatient and ****. He's not prepared for the lecture and BS a lot. You have to be extremely focus in his lecture so that catch ONE single key point out of 30mins BS. It's hard for me to say which professor is the best in De Anza, but, definitely Tong is the WORST professor in my life. I'm glad to have Gary Fisher for my O-chem.

how did he get hired? what are his creditials? where did he get his degree?? is it even chem related?? he makes on the average about 20-25 errors a day in his lectures. if you can self teach yourself the materials and get a hold of his old exams which he recycles, then you're set. other than that...you're gonna need to do alot of praying. fire him!

The worst teacher I've come across. He even beats Calgher for the worst, and I think Calgher is complete****. That says a lot. Please, if you see his name on the Schedule of Classes, DO NOT take his class...unless you want to torture yourself.

Senile. Easy lab report greater. No formal prelab required. Just write observations any way you want. He does not mark you off if you don't have it right away. Just have it when you turn in lab write ups. Crazy, crazy man. Try not to ask him questions, b/c he'll just go on and on. It's really annoying.

tong is the ONE of the worst chem teachers.. he is NOT CLEAR ON HIS LECTURES, HE GOES OFF-TRACK!!! i went into his office hours for help.. and he expected me to know the fukn material becuase he would drag the answer out of me when i was clueless.. he would tell me to go back to chem 50.. who does that ?!?!?!!? I DONT RECOMMEND HIM!!!

Can't believe how come he doesn't get fired yet. He loses his students' lab reports. His grading is inconsistent. He disappears during the lab period, and comes back in, saying "OK~~". I was so tempted to ask him what is "OK", but he doesn't speak English. He is so mean that he sometimes ignores students. Worst teacher ever.

wow ppl. are mean. well, it's true. he is not suitable for teaching. =( he literally picks on the ppl. who don't talk and ask them to answer questions. then he complains how we never remember everything from general chem. um yeah. good luck to all who are taking him. =) read the book, do the worksheets (memorize them), & yeah...good luck!

He doesn't teach at all! The test is very hard! Questions in the tests make all students confuse!

awful teaching style! very lazy. Never did what he promised. Tests are not easy at all. Always gets mad when students ask him questions. Grading is also CRAZY. you have to completely study on ur own. My suggestion: do not come to class. Its a waste of time. What else can be worse?

If you want to know anything about chemistry, DO NOT TAKE HIS CLASS. He sucks.He doesn't know anything about chemistry. If you know anything about chemistry now, you will forget if you take his class. Its a suicide to take his class.

He is the worst teacher I have had in a long time. His tests are confusing and don't reflect the material gone over in class at all.

even though i got A in his class, but he is not a good teacher. he didn't teach me much, and i have to study by myself. if you are a strong self-learner, take his class. if not, never take his class.

Does not really teach. Goes off on tangents. If you want to do well you have to teach yourself by textbook. Assigns a lot of work(trying to make up for lack of teaching skills) and tests are really hard. Probably wouldn't be hard if he actually taught instead of picking on students. Labs are easy, but really boring. Do not recommend!

The worst teacher in De Anza!

very bad thing if you guy take his class. i do not think he is good ,nothing to learn in his class. in class, he told a lot of himself and his background in lecture. he did not want to border or ask him about the lecture and unreasonable, and not responsibility.

Tong is so bad, he gives all sciences a bad name. He is Extremely condescending, as in any chance he gets, he will exploit how inadequate you are [Instead of "Good Job" he will say "GOOD! I'M GLAD YOU CAN STILL ADD!!"] Trust me, it is ANNOYING. His lectures are extremely messy, unorganized, & unclear. Don't take it, you will regret it, trust me.

OMG! Tong is sooo bad. If I didn't drop his class, the grade he would have given me would have completely destroy my 4.0 GPA. I swear I have never ever had a worser teacher. He loves to pick on student and I can't understand a word he is saying. HE IS SOOO ANNOYING! BAD TEACHER! Don't take his class. Trust me

Avoid at all costs. If hes the only professor available for u, take chem next qtr. Lectures and lab lectures are horrible. Unorganized, jumps all over the place and the board looks like a complete mess when he's done. Inconsiderate, writes small so that only he can see it. Doesn't think about other people. Take chem next qtr if hes ur only choice.

Though you can pass this class by spending a lot of time studying on your own, don't expect to learn anything from Tong. Rather than helping the class understand certain concepts, he directed us towards what we would need to learn on our own. After awhile, I gave up on trying to gain anything from lecture - it was mostly a waste of time.

Absolute worst!!!!! Do not take him! He says to ask questions it when you do, he'll just give you an attitude and a "well you should have read that in your textbook." expects you to read the chapters all on your own. doesn't really lecture anything important. Worst teacher ever!!!

Horrible! Couldn't learn anything. He only made me hate Chem more and more.

he is the worst chem teacher ive ever had. hes very hard and doesnt bother helping students at all. DONT TAKE THIS CLASS!

Completely incomprehensible, provides study material that is misleading and doesn't cover what is actually on tests. Refuses to answer questions in an understandable way (if at all), and yells at you for bothering to ask. His tests are entirely composed of trick questions. Spent 30+ hours on this class a week and feel like I've learned nothing.

wow there are so many ratings...i dont need to explain at all... but just one word.. BAD!

He is a very easy teacher if you study hard. I got an A in his Chem 1A, but when I was taking Chem 1B with other instructor, I felt I was an idiot. You will learn nothing about Chem even you study hard. Stay away from him if you can unless you just want an good grads regardless of the knowledge.

The suckest prof in my life. He is extremely not helpful, and teaches nothing. He doesn't explain the materials well. I study this class all by reading the book and asking the tutors, since his lecture is useless. Don't take this class and don't expect to learn good stuffs in this class.

No offense to this man, he may be a good person, but he is TERRIBLE at teaching. I used to like chemistry before taking his class. I blame all of my failures in college chemistry since this class on Mr. Tong. He doesn't bother helping students understand the real meat and core concepts that are used in the future. He should really find another job.

Tong is a great guy, he seems to know Chemistry very well. BUT!! He cannot teach to save his life. If you value your GPA or want to learn and understand the material for further classes, I suggest to take someone else. If you don't believe me show up on the first day of class and ask him ONE question, u will be more confused then before you asked.

Impossible to understand, won't answer your questions, and will make fun of you for asking. Grades very slowly and tests are super hard and not based off the book or anything you do in class. Gives review homework for chapters after you already took a test on it. You WILL fail the lab portion of the class. You probably won't pass this class.

He is a horrible person. He tries to teach but doesnt do good at it. everybody fails in his class

From a personal standpoint, Prof Tong is a very funny and cool man. But when it comes to teaching he is horrible in that he jumps from on concept to another and will not teach throughly. Though he's always open to helping clarifying things if you dont understand. Get his Primer and learn on your own if your taking him.

Spends plenty of class time for jokes and belittling the malinformed while glorifying his professional standing in his teaching community, he tends to rush through the core concepts of the subject. Little compassion for the underacheivers and overglorifies the teacher's pets. For those who prefer passionate, helpful instructors, seek elsewhere.

Don't bother ask him questions...It's better go to Mar.

I would drop his class; eventhough u might the smartest person on earth. Believe me!!

I would so drop the class if I were u. I got A+'s in my previous CHem classes; and had to retake this class. This happened to half of the class.

Recommend that you take some other instructor; better than repeating the course :( It not easily at all; I was a student with 4.00 gpa and this class lowered it; i had to repeat the course.

Just drop his class; not worth it; unless you want to re take it. The comments below are true. I was also a 4.0 gpa student until this class; had to retake it. :(

Uses, old slides from older textbooks that aren't even close to the class textbook. Not worth taking his class. NOt clear at all. Especially during lecture!!!! TAKE IT WITH A DIFFERENT INSTRUCTOR: UNLESS :(

Terrible teacher, try getting someone else, hopefully you will learn that he's extremely unhelpful, mocks your lack of knowledge on the subject and unclear about just everything. + great reading skills - bad grades from unclear lectures. Btw don't go to lectures just study massively, lectures are irrevelent. Good luck, trust me you will need it

Pros: He is nice and wants his students to pass. Sometimes cracks a few funny jokes. Cons: He doesn't know how to teach. Lectures are messy and unclear. Horrible test structure. Gets irritated at students when they ask for clarification. Rambles in lectures that are not relevant material. No study guide and doesn't give you good directions.

So bad at teaching. For example he tells us to ask him any questions. Then he will get angry and reply "I already told you!" Very unclear and speaks to the white board and not the class. He makes chemistry very difficult to understand. Do not take this teacher he is a POS. If you plan on taking this class do not expect to learn anything from him.

Nice guy, but terrible lecturer. Truly does not care about your understanding. Clearly does not want to teach or enjoy doing it. He is not the worst teacher (believe me, there are worse), but you are pretty much on your own. He mostly uses his primer pack. That is your bible for his class. Good luck if you take his class.

seems like a good guy, but should not be teaching. be ready to teach/clarify half of the material your self. i would recommend finding out side resources. very unorganized teaching!

Tong isn't a bad guy, he is just bad at teaching. His lecture are unorganized and not clear. test are base on previous exam, so get the primer is you are taking his class. overall not a good chem teacher.

Absolutely terrible professor, if you value your grade do not take this class. He is VERY unclear about everything, from lectures to tests. He is never prepared for class and often reviews the material in front of the class. Tests don't make sense and then he acts as if answers were obvious later. Unapproachable and rambles about irrelevant info.

Homer Tong is the worst professor I have ever had. I am three weeks into his summer Chem 1C class, and I do not understand how he is still a professor. His work/required knowledge for tests does not teach about the material. I have had to argue with him about every grade I have received. Avoid taking this classes at all costs.

I have no idea how he is allowed to continue teaching this subject. He is a very nice man, but is a horrendous teacher. He lacks organization, writes illegibly all over the board, mumbles to the board while thinking out loud, does not prepare before classes, and makes everything more difficult than need be. Just a few flaws...DO NOT TAKE HIS CLASS!

in his class right now...please please avoid him!! i agree with may previous comments. he writes messy on the board, and has a weird temper that irritates me. in lecture, he a horrible job on going over problems we need to learn. in lab, he takes forever trying to explain..he talks to the board a lot. i am not taking him again!dont torture urself!

Lectures are very confusing and he goes off on long tangents that are way to complicated for Intro Chem. He constantly says "you should know this already" when it is an introductory course and he has not explained it. Want to ask for clarification? Think again he will make you look stupid in front of the class and not answer your question directly.

if you want to teach yourself then take his class He doesn't make any sense rambles a bunch I don't understand anything you must study alot and read the entire book Avoid him!!He's horrible

He never explains much into his topics, yet he expects us to master all of the concepts on exam. He is very disorganized and do not care much about the students. You'll end up watching Khan Academy or going to tutor the night before the exam, as he really is a bad teacher.

Unorganized. Learn nothing at all. even though he gave us the past exams, we still can't answer them and mess with the exams.

You have to self study EVERYTHING. Luckily he created a chemistry primer, so you have to go an buy one, but the test is VERY similar to the practice tests inside the primer. You might be able to get an A by just studying the primer, but learning Chemistry from Tong is impossible.

EASY A if you buy his primer. Exams are in primer and notes in primer. Without it you would not do well.

Tong creates a primer with previous exams and class notes, so make sure you purchase that! He says the previous exams are the same but with different numbers, but make sure you have a strong grasp on the concept, and not only from memorization. He words his exams differently than the primer's exam. Make sure you have your mindset set on self study.

His lectures are terrible. Goes off topic a lot. Mostly about Germany. His primer is the only chance of passing the class. You need to self teach yourself the whole course. Instead of answering students' questions, he tells you "It's been 6 weeks and if you still don't get the molar concept, I highly suggest you consider dropping the course."

Mr Tong is a really nice person. His lectures are not good whatsoever. I did not learn a thing from his lectures. His labs are confusing but then again everyone just copied from each other. Tests are easy if you go over the primer. YOU REALLY NEED TO SELF TEACH YOURSELF FOR THIS CLASS! In the end i would not recommend taking him.

I am so dissapointed he is the only professor for chem 25. So much stress has come from this class. Do not take if you have other classes as this is self learbing entirely. He will not go over topics in class clearly or at all.

His discussions are always all over the place. He gets angry when he repeats himself more than twice and if students don't understand right away. He doesn't tell you what to study, he expects you to know everything. He does not go into depth of what will be on the test. If you can avoid taking him, do not take him unless you can teach yourself.

Horrible grader. If you miss one small part of the answer he gives you a zero right away. Forgets things a lot and doesn't stick to what he says. Half the time he's being sarcastic and complaining about students. All of his tests and quizzes are practically the same as the ones on his primer. Never learned anything in class. Would never take again.

One of the WORST chemistry professor at De Anza. Thong doesn't have a clear and comprehensible idea about how the grading will be handled. he presents the material in a confused way. Lectures are all over the place and you can't figure out what the main points are. AVOID at all costs.

What a lovely quarter ! I have never met such a person like him. He gives you the wrong answers to his own test questions before the test and make you all confuse about everything. When I told him you gave us the wrong answrs to these questions on the test. He said " you dont have to listen to your instructer!!!!! You have to read the book "

Worst teacher you can take for chemistry. The entire course is pretty much self study and he never lectures and when he does he derails and never explains the important parts clearly. The only reason passing this class wasn't impossible is because he has a primer that has all of his previous tests that he uses as a format for future tests.

His lecture is hard to understand. He is a tough grader.

Avoid if u can, class was stressful. Took him for Spring bc he was the only Chem25 prof at the time. Now for Fall, there are more teachers! Tong does not really lecture that well on the chapter points. Must read book yourself to learn. Purchase his primer at the bookstore for $11. Has prev quizzes & exams for you to study/practice & work sheets.

worst teacher ever !!!

He lectures like an electron.

He really enjoys teaching but he can't teach. In lab, he babbles for a solid hour before lab work. Lectures are worse since he's essentially inaudible. He once marked a question wrong but I went to ask him, he refused to change it because it was "my fault." If you want a chance to pass his class, study his primer, which is actually somewhat useful

DONT TAKE. His grading is unorganized. Doesn't return papers when we need it to study. Gave us HW, didn't collect it for the whole quarter. When we told him, he minus points for being late but never collected it to begin w/. We all had 2 days to finish CH1-9 Q (I did 22 pgs) Talks for an hr+ b4 lab, useless. I'm an A student except for his class.

Don't expect to learn a lot from his lectures. It's hard to understand and follow him, you're better off doing what i did; watching chemistry lecture videos from youtube during his lectures. Not a very good teacher, but he's a good dude. If you can teach yourself chemistry and do the homework he doesn't collect, you're good.E

if you love yourself dont take him. if you actually love learning dont take him. class is very disorganized, his lectures are really hard to follow. pls avoid him at all costs!

Once went up to him to ask an assigned question. 20 minutes later, he gave up because he didn't know how to solve it. Really? Also, one time he accidentally marked a question wrong on a test when it was right, but when I asked him to change it, he didn't because I "should have told him earlier." I'd rather take an extra year than take this him

Just look at all the other reviews, especially the ones with 10+ likes. He's not meant for teaching whatsoever. Honestly, you're better off showing up for lab and then skipping lecture since he can't teach. You might as well sleep in/go home early and study yourself than sit in lecture for an nearly two hours of nothingness.

Tests are ridiculous. He argues that since five people out of 60 got a B or higher on the test, everyone should be able to do the same. If 60% of your class keeps getting failing grades on tests, that should tell a professor something, but he's so stubborn. Heard it's his last year here, so great. Hope he reads this so he knows what he's doing.

Imagine Homer Simpson, but with a bit more chemistry knowledge and a not-so-humorous personality and you get Homer Tong

Does he even know how to grade? I basically failed every test with 50% on each and somehow I got a B. I'm not complaining but kinda shows you that if a professor doesn't know how to grade his own assignments that he's had for 40 years, then he should be nowhere near teaching students.

Expect to teach yourself everything. He takes zero accountability when most of his students fail his tests(the tests are extremely difficult) and he doesn't provide us with answers to practice tests or assignments so even though he assigns us a ton of work or practice I have no way of knowing whether I'm doing problems correctly.

I attended every lecture and took a bunch of notes, but you all should expect a 30 percent overlap between what he teaches and what he puts on the test

Avoid this professor at all cost. His lectures are not very clear (goes off topic). He expects you to learn on your own and when you ask for help he simply yells at you. Most of the time he would make you feel dumb for asking questions.

Avoid this guy at all costs. His lectures are useless, just him mumbling the whole time and mocking students. Your grade will be based off exams and labs only. He is rude, hard to understand, and makes you feel stupid. He assigns HW and forgets to collect it. If you're just taking this for GE, make it Pass/No Pass and study your ass off.

He is horrible. Run far far away. Chemistry is hard enough already. He makes it so much worse. His lectures are not correlating with his study guides or lesson plans, his labs are mostly lecture and a rushes experiment. Do not take him. Take anyone but him. I dropped his class because of how bad he was. His grading does not make any sense either.

RUN AWAY! He mumbles during lec.& writes TINY (& i sat in the front row).Hard to follow/understand. Makes you feel like an idiot for asking q's. Lab is 3 hrs long w/ 2 hrs of more lec. & rushed expt. He doesn't guide you in lab AT ALL. Primer is the only good thing. BUY IT. Tests are directly from there-He makes mistakes writing tests, catch them!

If you like buying products that do not work (or a service that doesnt serve), take him. Also, if you do not value your money, dignity, and education, hes a solid choice. Good luck!

Worst teacher ever, talks about everything besides the material he should be teaching. Won't let people ask questions.

This instructor teaches as a hobby, does not care about student success and ignores questions. I finished the class with no knowledge of chemistry. He doesnt explain material, is hard to reach outside of class, and doesnt help or explain in the labs, students were exploding beakers, no explanation on how to use the Bunsen burner, an he laughed.
