Not a bad guy, but very hard to understand, and the Cal 2 tests are very very difficult...I often studied for 6-8 hours the night before in preparation.
First off, he's a nice guy. Go to every class and BAM, 5 points on the final grade. Do all the online homework and another 5. He doesn't want you to fail, but the material is killer. Invest in a little extra study time with this one.
.....
Great guy. Easygoing, wants his students to do well. Yeah, he has an accent, but as long as you pay attention, it's easy to understand him. Offers LOTS of bonus points on final average.
Yes, He attempts to be a good teacher, but does not quite come through. His thick accent is what makes the course difficlut, not necessarily the material.
Good guy....easy to understand if you go to class and try to listen. Material can be tough, but if you do either the online, or the book work, you'll be fine. Go to class and do the online homework & you get 10 pts. on your final grade...plus he offers more sometimes. Great professor.
hard to understand sometimes, but he's a really nice guy and will help you if you put forth some effort
James is an awesome teacher. He doesn't teach very many concepts, just how to work the problems...which is enough because cal 2 in itself is just difficult. Teaches great and gives ample bonus points.
Wang is a great teacher.His class is EASY if you GO to class and DO the online homework.Gives 5 bonus points on your FINAL AVG if you are in class every day and another 5 if you do all of the online homework.The tests also look just like the online homework and some are multiple choice.Advice: when taking online quizzes, you can pause them.Take him
He is hard to understand. Although he tries to help, he is not very helpful. He gives a ton of bonus. Go to class because if you dont miss a day, you get 5 average points.
Most definitely the worst teacher I have ever had. I paid $1200.00 for this teacher, and I have taught every part of the class to myself. He gave us a quote from an ancient Chinese proverb the first day of class.... here's one for you Dr. Wang. "Is a teacher who can't communicate a teacher at all?"-- quote from a frustrated American Student.
I had to teach myself every bit of the course. His teaching methods are convoluted and difficult to follow. Definitely not recomended.
Ummmm I gave him bad ratings, but he does help some from giving ten ponts average at the end of teh year so I have no idea what to tell you, f ou are decent in math, a c is what you are going to get,, if your pretty ood a B and if you study your asss off an A
5 average bonus points for coming to class everyday he takes attendance and 5 for getting 80% of the online homework correct. Yes, he has trouble pronouncing words like trapezoid, but he is definitely understandable. His tests are from the easy book probs. He teaches by working example problems. Do the online work, you will understand it all.
Takes awhile to get adjusted to his accent. Doesn't require attendance but gives bonus points for going to class. I more or less taught myself the class with the solutions manaul (I reccommend it for CAL I,II,III). Test are pretty difficult, but he gives partial credit if you show your work. Drops lowest of 4 tests, excluding final.
Wang was a lenient teacher. I bargained with him for my extra credit AVERAGE points by simple mathematical reason. he is fun if you are a good student and i wound up with 10 average points (all homework and 4/5 attendance + we persuaded him to give us an extra credit assignment for a point) even if i made an 88 in the class i still got an A+!!
Means well, and if you have the time, can pay off with extra credit... but for double majors or students with heavy curricula (CBH or such), can be far too time consuming to accomplish an A or even a decent B. Take at your own risk.
Don't be worried by the foreign name, he is easy to understand after the first week. I loved his teaching and uses BONUS POINTS GRACIOUSLY!! Do your work and you're gold, the test questions are straight from the online hw/quizzes.
He is a really nice guy and gives bonus points for coming to class and doing your homework. The tests are straight forward and he makes the class as simple as possible. He is funny too!
Make sure to do the homework assignments. He gives the opportunity for a ton of bonus points to be added to you final average. His English is so-so. That could be a problem for some.
He's a little hard to understand at first, but you'll get used to him throughout the semester. It's a hard subject, but if you go to class, do the work, and get help when you need it, you'll do fine.
HARD TO UNDERSTAND, HARD TO UNDERSTAND. incredibly frustrated. i worked very hard and got no results. I had to drop the class.
He's nice, but that's about all. His teaching is horrible. When the majority of the class did poorly on a test, he did nothing to help us understand the material further and proceeded to put several of those questions on the final.
I had Dr. Wang for like 5 different math classes. He's hard to understand at first. He gave us bonus points for perfect attendance.
Hard to understand. Very frustrating to have to interpret him all the time. As if calculus wasn't confusing enough. And God help you if you don't pronounce his last name as "Wong" not "Wang".
This Professor is awful he cant be understood, his clarity is awful, he gives tons of homework, where you are more worried about trying to turn in the hw on time instead of actually trying to learn the material. His tests are awful he takes the hardest concepts from each chapter and section and puts them on the test. Overall I would never recommend
Tests are hard, final is IMPOSSIBLE, and by the way it's 40% of the grade. Had an A going into the final... not anymore. 5 bonus points for perfect attendance and 5 for bonus problems. Get anyone else by all means necessary.
5 bonus points for perfect attendance, and 5 bp's for bonus problems; He is very lenient when scheduling tests around your schedule. Lots of homework and a quiz to go with each section, but if you sit down & actually learn it, it helps. The practice test are similar to actual tests... if you try, ull do good. I got an A+ and barely went to class.
He spends most of the class working examples and usually finishes early. Hard to understand at first, but you get used to him. He is an extremely nice man, who even likes to know how you are done with his class. I think he will replace your course grade with your final if it benefits you. He also stayed longer if you needed more time on your test.
Not the best professor, but definitely manageable. A little difficult understand, but if you look over the concepts before class, you should be able to understand what's happening on the board. Doesn't drop grades! Missed the first test, got him to average my other test grades together overall. Homework counts for %20, so do it! Old but nice.
He is a bit hard to understand at first but you get used to it. 5 bonus points possible on each test, 5 turn in bonus questions, and 5 bonus points for perfect attendance. The online quizzes are a bit tough but doable. Overall, I would say definitely get him if you plan on doing any work. His tests are a lot easier than the homework too.
Dr. Wang is a decent teacher. All of his lectures come straight from the book and he usually dismisses class 10-20 mins early. A lot of online hw is required, but it's impossible not to make a 100 on it since the answers are available for every problem. Tests are fairly straightforward too. Study for the final since it's 40% of the grade!
If there is hell on earth, this is it. So much homework, the tests are not reflective of the HW assignments at all. This is where I have the biggest problem. His review tests are less than helpful as well. He doesn't seem to get that not everyone loves math to the degree he does.
I found it hard to understand him at first, but it gets better. Also, the tests are directly from the homework.
I love Dr. Wang. He is a little difficult to understand at first, but you will get used to it. He's corny and wears the same outfits a lot. His online homework doesn't take much time at all. Most of the time it gives you the answer anyway. Tests are pretty straightforward. And he lets you out early. I would take him again in a heartbeat.
Do not take him. He is not a very good teacher. You cannot understand him. He can barely speak english. Not very helpful outside of class. Take any other teacher but him.
This class just sucks in general I don't think it would have been too much easier with another professor.
At first, you think, oh crap I can't understand him, but its gets better. If you've taken calc before then I recommend this class. Tests are hard and so are homework but he is easily persuaded into canceling class around breaks.
nice and his teaching is fairly understandable, but he has a hard time understanding and answering questions. Also, he hardly gives partial credit. He does not give points back. Don't even try to tell him you deserve more points for something, because you are wrong.
I had no problem understanding his English. He's a really patient teacher. We had the most annoying kid ever in our class and he stayed patient with him the whole semester. The homework isn't that bad, and if you understand every problem in it, you'll ace his tests.
Dr. Wang is a great teacher. He gives you online homework with the answers to it. You can't not make a 100. Quizs are online, but they are generally identical to the homework. The test are generally the same as the homework, and they are not that difficult if you study for them and understand the concepts. Plus, every test has bonus points on it.
Calculus is calculus. Wang does a good job of explaining concepts. Class rarely lasted more than 30 mins. Tests were out of 110 so a little help there. Accent was sometimes hard to understand but I got used to it.
He is a very nice man just seems a bit too old to teach. His pacing was crazy, he spent a great deal of time on the first 2 chapter and we went through the last half of material at break-neck speed and there was a difficulty spike in his tests. Homework and especially quizzes are very hard. Expect to teach yourself most everything.
Not a hard class, but he is a bad teacher. You can barely understand what he's saying. He doesn't understand questions and he doesn't return emails. He does the bare minimum and it is really frustrating as a student.
Dr. Wang knows what he is talking about, but his accent is sometimes hard to understand, though you get used to it. Very nice guy. Calculus is calculus, but he does many examples and I was still able to do well in the class with having next to no prior experience in the class. The homework is very helpful. Class usually got out early as well.
Don't take Wang. Seriously. Don't. Nice guy. But he's the worst math teacher I've had (and as a math major I've had a lot.)
His English is very broken and hard to understand. I do not recommend taking any of his classes. If you want to teach yourself all of the material and show up to every class even though you won't learn anything from him, then this class is for you. He does give 5 bonus points for coming to every class though.
My God, where to start. First of all, you can't understand a dang thing this man says. Second, if you have never taken Calculus before, steer clear of this man. Luckily, I took the class in high school, so all hope was not lost. He does offer 5 points bonus on your average if you attend every class, and the web assign homework is very easy.
Having never taken Calculus I find this to be an extremely hard class. Class consists of him reading slide after slide in broken english. Can barely understand him. Lots of online homework, although it is easy. Tests are very hard. He also moves extremely fast. I have friends in different sections of Math 125 and they are an entire chapter back.
Dr. Wang is extremely smart. He knows his stuff. It's a shame that he can't share that knowledge with us clearly. To put it short, Dr. Wang does not speak English well AT ALL. He goes through and mumbles Powerpoint slides, but doesn't explain much due to the language barrier. Only reason I survived this class is because I took calc in high school.
I had taken calculus before and got an A in the class. Dr. Wang makes that almost impossible. He is very bad at explaining the material covered, and his teaching method is to read off of a powerpoint without working out any examples. His English is very poor, not just because of his accent, but he doesn't know the language very well at all.
He is a really sweet man. His English is fine, but sometimes you may have to rephrase a question. The homework basically forces you to get a 100, and all test questions come straight from homework. I had taken calculus before, but he taught me more than I already knew. He gives 5 bonus points on your final grade for perfect attendance.
Sweet sweet guy but very hard to understand in class. He's very hard to communicate with because his english is not that great. His tests are not that hard but studying for them is very confusing because there is no direction on what to study. His class takes effort but it is not impossible. He gives a lot of bonus if you ask questions on the test.
Wang is very lenient with his partial credit on tests, and if you go to every class, you will get five extra points added onto your final grade in the course. Homework is all online and is very simple. Test questions are generally based on homework questions. He is such a sweet man; just put in some effort- you'll be fine. Not a horrible class.
Not the best teacher, but he is the most adorable old man you will ever set your eyes on. Seriously, sweater vest and booty game is strong. Also, find someone to sign you into class & only go in for the exams;you'll learn the same amount by not attending... But you want to be signed in for class so you can get the 5 points of extra credit.
Lectures are hard to understand, but make sure you go or have someone sign you in because perfect attendance will earn you 5 extra percentage points at the end of the semester. Fight for partial credit when you get a test back; he'll usually give it to you. I had a D at midterms and finished with an A. Good thing I didn't take a W.
He is hard to understand, reads notes directly from slides, doesn't do examples. I had to teach myself from the book. Only 2 tests, 6 homeworks, and a flash card cheat sheet for tests. Bonus points for perfect attendance.
Did good in Cal 145, decided to take honors Cal 2 because it couldn't be that bad right? Wrong, he's a nice guy who asks if you need help before every lecture, but he's hard to understand so nobody pays attention. Works examples out of the book. Puts extremely difficult problems on exam. Did all the homework and classes and still failing.
Wang is a very nice man, if you go up and ask him about a missed problem on your test he will give you half credit. His accent is very hard to understand but his tests directly correlate with the online homework. Tests are tough but he tends to scale them and you can drop your lowest test grade. He scales your average. I would take him again.
Not going to lie. Tough accent to follow. If you have taken AB or BC calc before in high school, you should be fine, but if this is the first time seeing the material, you will experience some difficulty. Go to class everyday for 5% extra credit at the end on total grade.
Yes he's Chinese and has an accent, so he is somewhat hard to understand (especially if you've never taken Calculus before). If you've had calc and understood the basics, you'll be fine as long as you attend class and do the homework (on the same day as the lecture or you'll fall behind quickly). If you haven't, find a tutor.
I took calculus in high school which is the ONLY reason I'm passing. Nicest guy ever but hard to communicate with. And tests aren't easy either. Covers information that was never covered in high school. Homework and quizzes are online and aren't too hard. Attend class every single day to get 5 bonus points.
My friends and I call him the "Wong" professor. He is awful. Very hard to understand during class. He will begin a problem and then not finish because he can't figure it out. His tests are ridiculous, and he doesn't give you enough time for you to complete them. We were also assigned over 60 homeworks and quizzes.
Not a fantastic teacher, but it's just calc 3, so just reading the textbook is all you'll probably need. Plenty of online resources if you just google it. Homework is worth a ton, and required. Honestly, you get five tries on every homework problem, and it gives you the key after one guess, so always do it even if you just copy the answers it give.
Avoid if you can. THIS CLASS IS FOR PEOPLE WHO ALREADY REALLY GOOD AT CALCULUS. He will not teach you much. Homework and reviews do not correlate to exam. He's a rather poor explainer. He gives bonus points for attendance. He does math in messy cursive. He was really unhelpful.
I love Professor Wang. I took this course at a community college and the content is very similar. His method of instruction is consistent and he presents ideas in a clear and concise manner. He's a sweet person.
I had him two semesters in a row, cal3 and difeq. He has a pretty heavy accent; it's something you get used to if you listen. He has a consistent style - ASK QUESTIONS IF YOU HAVE THEM OR ARE CONFUSED; he'll explain. Usually works examples in class. Tests aren't that hard and correlate with the homework, which you should do. The textbook is helpful
A nice, soft spoken, old asian man with an accent. I couldn't understand him when he spoke, even with the microphone he spoke into. His handwriting was also indecipherable at times. Eventually you catch on to how he writes things. Bonus for perfect attendance. Online homework that is really easy and helpful (shows worked out solutions).
Homework almost daily (but it isn't due the very next day). Tests are tough but not impossible. Lectures are crazy hard to understand and his handwriting isn't the best. Go to office hours and he helps you. Ask questions. LOTS of extra credit for attendance so make sure you go! If you've taken Calc 1 before, you'll be fine :)
He doesn't explain what he is doing in the problem and expects us to know each step. He also messes up on test answers and then we take the lash from the mistake.
This is by far the hardest class I have ever taken, mainly because of the professor. No matter how hard you try, you will not be able to understand him. In just one semester, we had 75+ graded homework and quizzes that were not easy. The tests are IMPOSSIBLE. ABSOLUTELY DO NOT TAKE HIM. WAIT A SEMESTER FOR A BETTER PROFESSOR. IMPOSSIBLE.
This class is borderline impossible if you haven't taken calc before. Wang has a very thick accent and does not teach well. I taught myself the entire course using the homework and tutors. Tests are tough but close enough to the review. If you attend every class you get 5% ec and he curves at the end too. Homework every night. Take another prof.
Dr. Wang is one of the nicest professors I've had, but his English does make class a little rough. Really, it's not a matter of understanding him so much as it is one of being able to ask questions- if he doesn't understand you at first, keep asking until he does. His lectures can be dull, but tests (100% of grade) are verbatim from the homework.
If you want to teach yourself every bit of material in this class take Wang. His lectures are confusing because he does not explain what he is doing on the board very thoroughly,his notes are scattered across the board, and he often skips steps. His tests are not that difficult but make sure you watch youtube videos on the material. Do not take.
Professor Wang is an old asian man with a thick accent. He's very hard to understand but you get used to it. If you take Wang for Diff Eq be ready to put in lots of time on your own. I had to teach myself a good quarter of the material. This aside though, Professor Wang is a really nice man and tries his best. Not nearly the end of the world.
Wang is such a sweet guy! There is a language barrier. Just reads off slides. Lots of homework, but you can find most of it online. After he gives a test back he will dedicate that class day to go over the test & allows you to go up to him after class and receive partial credit which averages into about 10pts you can get added back to your score.
James Wang is a very sweet old man, but is not a good lecturer. However, he is willing to discuss problems outside of class and in labs. Be sure to complete homework a day early for 10% extra homework credit, and heavily study from the practice tests/ textbook. Overall, this class is passable, but you will need to work for your grade.
Dr. Wang is a nice person, just sometimes cannot explain materials very well. As long as you know how to write rigorous proof, it will be an easy A for you. Most students who complain about his class do not know how to study math, not Dr. Wang's problems.
I am a sophomore taking differential equations with Dr. Wang. Out of my 2 years at UA he has been the worst professor I've had. His lectures are awful because he mumbles through them and skips steps as he writes on the white board. Be ready to teach yourself EVERYTHING.
Definitely the worst professor I've had at UA. Would definitely recommend taking someone else in the summer. I had to teach myself all the material, and quite honestly didn't put enough time into doing that. He seems like a nice old man, but he was actually pretty condescending when I went in for help. Couldn't really understand him while lecturing
James Wang is a really nice man but not the best lecturer. He uploads his notes to Blackboard which were very helpful and clear. He lectures straight from the notes so as long as you study the notes, you won't miss anything. Tests and grading was very fair, nothing came up that had not been covered. If you get perfect attendance you get 5% bonus.
I would go to class and you couldn't understand what he was saying because he mumbles the whole class. He also would ask some students if he was doing the question right so I lost hope early on. I stayed the whole semester but it did not end well. The test can be easy if you have the old exams but if not it hard to know what to expect.
