MATH4B . Scroggin T 25 Days Ago

Good lectures and answers questions well. Very easy going and keeps the class interesting and HW and lecture materials isn't too dissimilar from the tests. Gracious with points on exams and grades through errors. Has lots of office hours and was willing to stay overtime to answer questions. Overall great professor and loved the class.

I appreciated her grading! However, her lectures were confusing. I was better off studying on my own. She allowed a rewrite for the midterm which was generous and she truly cares for the class and students, she just wasn't good for me. I would recommend taking another 4B prof if possible.

Honestly the best math prof I've had at UCSB. She was a very engaging lecturer; you could tell she wanted all of her students to succeed. Her midterm was pretty light, and her final exam was definitely a lot more difficult but fair. Loved having her as my prof and would take a class with her again

Such a cool and funny professor who wants you to succeed. She messes up on notes often but responds to emails fast. Homework after every lecture is doable and more comparable to tests than what we do in lecture. Midterm was chill and she offered rewrite for more points! Final was a curveball but fair and graded more leniently! Would take again

Homework due after every lecture (3x a week). Nice person and wants students to succeed, but her lectures are pretty much useless. Had to self teach myself the entire course. Her tests are way more difficult compared to other classes since she expects a crazy understanding of math. Would not take her again and just do an easier professor.

Course is tough but manageable, midterm was way too long for the amount of time we had but final was fair. No curve, some participation extra credit, QR attendance code for lectures, Webwork HW. Very understanding and wants to see students succeed.
