Ling's approach to mathematics using basic concepts, not distracted by coordinate axes and formulae, is refreshing and exciting. His style of extremely formal speech, which he reproduces thoroughly on the board, confuses many students, but I like it, too.

good teacher, teaches slowly so you can understand, and doesn't give too much information all in one day. gives practice tests that resemble the real test. easy tests.

One of the best teachers I've ever had. His class is not easy but great. He explains concepts very well. You have to work hard to learn it. This is not a class to teach you how to use calculators. Just because you didn't get a good grade does NOT make him a bad teacher.

Mr Ling is perhaps one of the most confusing teachers that I have ever met in my life. I find that his approach to mathematics is very abstract rather than concrete. Hes not all about using calculators to find obscure numbers with a bunch of decimal places. Overall he is a good teacher. if u get him

His word choice for teaching is very sophisticated and as a student its very hard to understand even with an average vocablary. The grade is based all on test so its tough to earn an A. My math skills are bad due to poor foundation in highschool and its a big leap between the way this professor teaches compared to my HS teachers.

An excellent teacher. The people who don't like him probably didn't work hard enough. The complaints about his use of the English language is simply a reflection of everything that's wrong with American education, and in particular, American students. If

He is an excellent teacher, need to work hard to get a good grade, problems in exams very much like problems he talked in class, so taking notes will be helpful. you will be able to get A in exams easily if you do the work. by the way, you gotta be aware of the final exam.

He is extremely nice. Always answer every question u have. He's one of the best Math teachers in CCSF. People who don't like him are lazy. He is not that hard. Always gives out the practice test before the real test and the practice test tells u just about everything on the test. Very easy. Highly recommend to take his class (I had him in Advanced

One of the best professors I have ever had in CCSF. He tells the very intrinsic meaning of mathmatics. His class really made me to start liking mathmatics, and every student should take his class!

Mr. Ling speaks with a certain vernacular that many students find hard to understand; however, he makes math very interesting (and hard). He really wants his students to understand math. If you want to learn, take his class but he is very hard on tests.

His lecture was somehow helpful. This applies to any math class; homework and solving problem are crucial when comprehension of material is concerned. He wasn't the clearest teacher ever but he had some good qualities such as sample tests right before the each test, which were so simlilar to the real tests.I failed to get an A but still got B+!

No homework. Extremely easy to get A. I got A+ because I attended his class very often

Be warned, this class is only for students willing to work HARD. If not, don't even try to take the class. However, if you want the best math education available at City College, take Ling. The material is very well thought out, and his love of the subject is clear. You will be well prepared for mathematics on the university level.

He's a nice teacher.Easy to pass.

Best teacher I've ever had. Seriously. His level of teaching calculus IS hard. But if you put in a ton of work, he'll take you places. And the point is - he DOES take you there. For someone, who never really found any inspiration in math (I just wanted to get the right result and pass the class), his lectures were truly awesome.

Cool guy! I never thought a math teacher can be like him. You can learn lots of useful thing in his class! He also teach you how to be a real college student!

I've taken Mr. Ling for the past three semesters and I believe that he's the BEST teacher I've ever had in any subjects. Everything that he puts on the board is very logical and clear to someone who's been keeping up with the class. His office hours are extremely helpful. If you want the best education in math, he's the professor you want to have.

His emphasis on studying theorems and definitions really helped me develop my problem solving skills. He is very helpful during office hours. He's a very good lecturer and makes his exams difficult. I know that most people use this site to look for teachers that will give them an easy A; he's not the person you're looking for.

many students keep asking question in class; he's still patient to answer. He teach theory n proof in class.i think it's borin.but his test is easy at all just follow his practice test.the final is kind of difficult since there are no more practice final..hahah..if u ar interested in math or u hv already know math deeply,u can take him

He is extremely knowledgeable but often condescending. However, he has an open door policy and is always willing to discuss math with you. If you complete your homework and practice tests, you will be well prepared. Heavy on theory, less on practicalities.

Mr. Ling's trigonometry class demanded that students develop a deep understanding of the material and are able to apply that understanding creatively. The exams are very challenging but his grading system is unusually forgiving. His approach is very formal, relying heavily on unambiguously defined terms and proven principals. I loved his class.

Gary Ling is an excellent, excellent lecturer.

Excellent professor, but very difficult to succeed in his tests. He got me interested in mathematics beyond what I thought I was interested in. If you want to learn proper mathematics, and will put the time and effort to learn, this teacher is the one.

If you are truly interested in deeply understanding math, you absolutely must take Mr. Ling's classes. He welcomes questions and is almost absurdly exact. He has a very dry wit. His grading system is very generous though his exams are HARD.

Very difficult class, but if you are interested in math, it is right class to take. He welcomes to answer questions, and he is knowlegeable. Your grade is base on your test, no homework, but you have to do the practice test that he gives out. if you dont know math well, and you dont work hard, dont even try to take his class

Lazy people and stupid people will consider he is the worst teacher in the world, Hard working people and smart people will consider he is the best greatest nicest in the world. I am smart and lazy, still consider he is the best, because I am math major.

I didn't do any homework during the semester, consequently, was unprepared for the final and got a B in the class. Don't repeat my mistake, do the HW. █

Genius at math, not so genius at teaching, very hard class. No hw required, no practice tests, one extra credit for the semester. Barely got an A.

Good prof. His classes are not for people who just need to pass a math classes. Go to class, take all notes, in the order his gives it. I look for teacher like him challenging who know his math. Lazy students stop given bad ratings his class are for science major people. Only science major people undrstand each. Take his class iff U like it.

If you just want to pass. Choose another. If you want to learn math. Choose him. You will know math is something more than a tool.

If u major in math like me, u should take his class which is extremely tough but worthy. I heard that he is the hardest one in Math Department at CCSF!!!

He is really really hard. But im grateful to have taken his class, he makes me "understand" the very core of the material, not just merely memorizing formulas in order to ace on exams :) he is simply smart and a very friendly teacher too!

Very good teacher.. very clear and helpful.Just as long as you show up and do the work you will do good.

Great teacher.Just as long as you show up and do your work you will pass.

If you really want to study math with a real university level, take him. His notes with his own style is professional, and furthermore, he has a unique mathematical insight!!! If you want to get an A, you are supposed to pay heed to every exam. Do not reckon the final is easy because the final is comprehensively tough!!!

Gary Ling has high expectations but offers so much in return. Try not to miss class and write down EVERYTHING!

Professor Ling is great. You're expected to have a good understanding of the prerequisites required for the course. He teaches you the core of the material, he wants you to learn, not just memorize formulas. If you plan on taking him, attend every class meeting, and study often. I took him during the summer, and it was definitely a challenge.

He is a difficult teacher, but if you DO ALL THE HOMEWORK, go to every class, and go to his office hours with any questions regarding the hmwk or practice tests, you'll do fine. He does everything he can to make passing the class possible; he HEAVILY curves tests, and he drops your lowest test score out of 4. Grade is based on 3 tests, 1 final.

Gary Ling is one of the smartest professors I ever had. He will teach you math techniques that aren't in the book. I'm in Cal now, and math has been a lot easier after drilling with Ling. Take him if you're interested in math.

very good teacher. his appearance makes him like seem like strict teacher but he's very nice. Does his best to help u understand during office hours. Teaches the hard way to solve a problem first to help u understand the logic behind it then teaches you the shortcuts. Very organize when he writes unlike my cal prof who writes all over the place.

The single most brilliant teacher I've ever had, probably the most brilliant person you'll ever know. A lot of people on here complain that he is too difficult, bottom line is if you are responsible enough to take an intense university level class which strengthens your critical/logical thinking, take Prof Ling. Otherwise you will fail

His a Great Professor! If you want to learn, take him; you'll learn math in depth. Sure, his class is challenging but if you don't miss a class his lectures are helpful. His really approachable for questions and want you to come to his office hours. He always ask in class whether everybody understood the problem before moving on.

Don't take him for an easy A. He is a frighteningly good thinker, and he's going to teach you to think. You will feel uncomfortably stupid but he'll make you smarter in the process. He didn't make us turn in homework, so test scores determined the entire grade, but he grades on a 5/6 scale and was ridiculously generous with extra credit. <3
