More Selected Exercises:

Just the homework is not enough for you to get prepared for the quizzes and exams.

You should do as many exercises as you can. All exercises on the textbook are

valuable. If your schedule is so tight that you are afraid that you are not able to do

all of them, you may try this still-not-so-short list first. I made this list by myself on

my own taste. Working out all problems in this list may NOT guarantee a good

score for this course.
