Summer 2020 - Professor Lew is absolutely fantastic. Having come in with little to no programming experience (AP CS in high school), she makes learning R fun. Especially during COVID, she has been so understanding of students' struggles (e.g. recording lectures, providing opportunities for up to 10% extra credit, dropping lowest grades). Though she might seem intimidating, I would recommend anyone to attend her office hours at least once: she has so much professional experience in the stats field (i.e. not just as a professor) as well as so much wisdom to offer. This class is primarily based on projects and assignments, and unlike the other professor who teaches Stats 20, there are no formal exams. I'd say that it is very easy to earn a decent grade if you put your best foot forward; even if she were not as lenient because of the pandemic, I'd assume it'd be the same. Although I haven't received my final grade yet, I'm very confident about my performance in her class because she makes it clear how to earn points/what she's looking for (tip: don't over analyze instructions!). Some other notes: (1) there is no curve for the course, though I don't see when one would be needed and (2) don't get the recommended textbook. Because of her, I feel like I have a solid understanding of R and have decided to pursue a minor in stats! I'd love to take any future courses with her.

Fall 2017 - Horrible horrible class. I had crippling anxiety and walking into this class tipped me over the edge. Her homeworks are overload and are carelessly created (full of mistakes and unclear directions) -- however because of this she is lenient on the grading. The group "quizzes" she assigned took an entire weekends worth of time and she ended up handing out A's to everyone that completed it. Contradicts herself a lot during lecture and has an attitude. For example in the beg of the quarter she would get mad at people who would just listen to her instead of taking notes, and she said "What are you guys doing? You guys should be typing and not just listening... you need to turn this in. Please get busy". Later on during the quarter when we are typing what she's typing, she yells "Can you guys please stop typing. Just listen.". Always lets us out late -- this is a problem because she opens up submission forms for in class participation activities when class is supposed to be dismissed and she talks about the weekends homework assignment after the class is supposed to end.... always end up being 5 minutes late to my next class. Last thing: Grading is very inconsistent. First 3 or so quizzes were grader rather rigorously. Average was a C, but towards the end the quiz averages were 90-95. Not sure whether this class was curved or raw scored, but if it was curved, this method makes it impossible to beat the class average and better your grade especially if you got off to a poor start. Tips for prof: End class on time and make more manageable homeworks. Also keep grading consistent please.
