Professor Dai is an awesome person. He enjoys to tell jokes and he likes to make his students laugh. Midterm and Final are all homework based, so if you do the homework, tests should come easy. He teaches general math concepts and then incorporates examples, which really help understanding the material.
This professor is one of the best I've had. He has a great sense of humor and if you pay attention in class, you'll will understand it 100%. The homework also helps you understand and it usually isn't a lot of questions. Take any class you can with him. Highly recommended.
had almost no clue what he was saying first day, but after a few lectures you understand everything
His lectures are not necessary to go to because you could find everything online, but they are helpful since most of the homework is based off of his lecture. He does have an accent that you have to get used to so it is tough in the beginning. But once you move past that you can just follow his notes for the homework and tests, since they are clear
not a bad professor. He spent too much time with his drawings and little explanation but his exams were very similar to the practice exams he posted so that made it easy just get help beforehand and easy final and midterm
A nice little Asian guy. Tries to make jokes during class but he can be hard to understand sometimes. I would recommend taking CLAS and you will pass this class with an A. his tests are quite easy if you keep up with the material. DO NOT BUY THE BOOK...waste of money. you never use it.
he was really hard to understand, though he tried really hard to keep the class entertained with his little drawings and jokes
Could not understand anything he was saying. Eventhough he is a very smart, nice guy he does not know how to teach one bit. Midterms and Final so much harder than the practice tests. Run while you can!!
Nice and fair teacher, but don't expect to learn anything from him. I hadn't learned any calculus before this class which put me at a pretty big disadvantage considering that my TA was worthless and I never went to lecture. I scraped out a B thanks to CLAS, but I felt like I could have done much better with quality instruction.
Very easy class. The midterms and the final were very similar to the practice exams he posted on the website.
Class was fine. Professor handed out comprehensive practice tests and solutions. No reason to get less than an A if you put in even minimal effort. Freshmen tend to go to lecture and talk the entire time/not study, lower the curve for everyone else, then run to ratemyprofessors.com to cry.
This professor was not helpful one bit. I am so upset I stayed in this class, I should have dropped it once I knew he wouldn't teach me a single thing. Shouldn't be teaching.
Sounded more like he was trying to teach himself the material instead of the class. And he always avoided questions from students.
Good Jokes in class to keep us entertained.Nice Guy as well. However, midterms and final was extremely harder than the homework and practice tests. Does not explain very well and assigns homework far too easy. Do not recommend him for any Lower division math courses unless you are a math genius
This class was extremely difficult. Homework is very limited and does not give enough practice for the students to grasp the concepts at hand. The midterms and finals were all very hard. Dai is a smart man but is too smart for the class.
Prof. Dai is a really good teacher. He explains things really well. I get everything unlike someone I know... Ohohohohohohoho~ Ohohohohohoho~ Ohohohohohohohoho~
Great guy, terrible teacher. Constantly blows past steps w/o explanation. Puts random stuff on the homework that was not touched in class. Really nice guy, just not a great teacher, too smart to teach this low level of a class, he assumes everyone shares his math brain.
Wants you to do good in the course. Very helpful. Good examples. Explains things clearly. Homework can be difficult but his tests aren't too bad. He listens to students comments. Math 102B is easier than 102A.
Stable, professional class. 240b was a little easier than 240a after some adaptation to specifics of geometry.
This course was really hard for me and Dai didn't help. His tests were harder than the homework and his lectures were unclear but the subject matter was difficult so i don't blame him for everything.
Small class, professional invironment. Lectures are rather introductory and supplementary for a lot of reading and exersizing (what is good for me). The course is extremely difficult unless you are fluent in algebra, analysis, and topology.
Hard class. Good prof. He tries to explain things well and wants to give you an A. He jokes are a little random but appreciated. Office hours are helpful if you don't understand homework. He wants you to learn it and he wants you to do well, so he tries hard and it helps.
funny teacher...he's a great lecturer and has a really odd sense of humor. He made me laugh pretty often and understands the need to ligten up when it comes to math.
goes around in circles and doesnt know what to do sometimes...then just gives a joke to keep everyone in the class and get a decent eval
