Although difficult to understand, she is a pretty good professor. Take advantage of her practice tests because they are really similar to the actual one.

Really good teacher. Gives extra credit. Tests are almost exactly like the practice tests. If you have to take math, take this class.

By far, a much better calc teacher than my high school teacher. She has an accent, but easy to adapt to. I went to every lecture & actually like math. She's GREAT! Take her if you get the chance to. My fav math professor by far. Take CLAS too! Helps tremendously!

Professor Joo was wonderful. Although she does have an accent it's easy to get use to. She's always well prepared for lectures and teaches the material well. Her midterm and final are almost exactly as the practice ones she gives. She give plenty of time for 20-25 problems of homework. It not hard to get an A in her class.I recommend taking her.

Though her accent took a while to get used to she definitely knows what she is doing and covers every concept systematically with a lot of example problems. The homework assignments are hard but they prepare you for the tests and the ta's will do the them for you during discussion. I did not touch the book last quarter and got a B+

i took her class S09;went to class, did HW & extra credit, studied hard for solid A. real final was HARDER than practice final, but she had prepared us with in-class examples & HW, so I still managed to do well. very helpful & good clear lectures, wants students to succeed. didn't even need CLAS, just studied on my own.
