Pretty unclear lecture that could hurt to watch but Greenfeld is consistent with the textbook. For the most part, her responses to questions were either vague or more confusing. Going to her OH can help because she is approachable and knowledgeable, but there are alternatives provided. The TA's were great and the Professor does provide past/practice exams. I did not look forward to lecture but it did reinforce my learning of calculus.

This was Greenfeld's first quarter teaching 31a, and it was painfully obvious. While she does seem knowledgable about the material, she does a horrible job explaining and teaching it. She fails to actually answer students questions, and to be honest you are better off learning from the book/discussions/watching youtube videos than actually going to lecture. The material on the tests is nothing like what is seen during class or homework. As for grading, she uses two different methods: 10%Homework+25%Midterm1+25%Midterm2+40%FinalExam and
10%Homework+30%Bestofthetwomidterms+60%FinalExam, she will use whichever will give you the higher grade. The top 25% will receive an A, following 50% a B, and the rest C & D's. If you don't do well on any of the tests, your only hope for getting a decent grade is praying that the curve helps you. Professor Greenfeld isn't a bad person, she's just a really really bad math teacher.

HORRIBLE HORRIBLE HORRIBLE. This has been the worst class of my entire life no exaggeration. This professor makes you wanna pull your hair out and she is not helpful WHATSOEVER. The tests are not at all like the material learned in class and are too long for the amount of time given. She is not able to answer questions in lectures and is not considered with how low the class averages for both midterms were. Just do yourself a favor and do not take her unless u wanna fail
