Not too easy. Not too difficult.
Math 101 with Gao is a very by-the-book, standard math course. Attendance in class and completing the assignments will more or less get you the content that you need to get out of the class. Gao doesn't go out of his way to make things tricky, and his personal teaching style makes it enjoyable in parts.
Having already taken the AP Test for this class, it was good having a review of sorts to give me the foundation for other courses in the future.

Advice for students:
Be proactive about anything that you're confused on. If you don't understand it now, it's likely to come back to haunt you when more complicated concepts are built upon the subject.
