I took her 130 in Spring, plan to take 150 with her again, she is a really smart professor, from what I remembered she was able to answer all questions we asked during the lecture. 3 Exams, 4 Quizzes, and A LOT Pearson HW. Nice prof. Take her! But not 150, save the spot for me :-), only 9 spots left and my registration time in 2 days. :-(
