Rating: 5.0/5, difficulty: 4.0/5
I learned so much from her class and she was always very willing to help us outside of class. She is very kind, caring, and thoughtful. Her class content was a little bit challenging, but she taught it very well. She is an inspiration to all her students. If you ever have a chance to take her class, I definitely recommend it to you.

Only teaches to the smartest student in the class. Is extremely disorganized, tests on concepts not clearly taught, and frequently uses incorrect or incomplete notation. She is extremely out of touch with the class's level of understanding. She put qualifier-level questions on her exam. Crams way too much material without clearly explaining.

Simple class. I have had experience in R with previous STAT classes, and this class starts "from scratch". It does move rather quickly at times, but few homeworks that are simple are manageable. Midterms are 40% and the final is 35% though, but the first midterm was rather easy if you followed along in lecture and studied for a bit to refresh.
