Terrible professor. Does not provide anything useful for the class and has extremely hard exams. He also does not curve and expects everyone to know the material, so he rarely gives out partial credit.

If there is any professor to chose from other than Chai please take advantage and avoid Chai at all costs. He contributes nothing to the success of his students. He provides no practice review for tests, doesnt let anyone use a notecard, says he will provide all necessary equations but doesnt specify which ones. By far worst professor Ive had.

I recognize that teachers catch a lot of undue flack, and that people love to blame teachers for their shortcomings, but god damn. I genuinely don't understand how Chai holds his job. This course could have been offered online with no instructor whatsoever and it would have been just as effective. Chai contributes *nothing* of value to this course.

Wow Chai is so unbelievably bad. I do not think I learned a single thing from him eventhough I attend every lecture and stay attentive. He really is not able to get the point across and instead just gives a bunch of definition and works out VERY simply problems VERY quickly which is an ineffective way to teach. Avoid him at all costs.

Unfair grading. One of the lowest class averages I've seen at UCSB, yet he doesn't even curve the class. You're lucky if you just manage to pass the class.

So I've had him for two math classes so far and he's actually a great teacher! People blame his accent/teaching style for not doing well in his class instead of themselves for not learning the material well enough. Yes, his courses are challenging and tests are hard, but it's doable. Chai cares about his students and wants them to succeed.
