Definitely one of the best math profs I've ever had! The questions on tests always had familiar concepts; it's just a matter of self-discipline when it comes to studying. Ograin gives out about 10-20 practice problems per week, but only assigns 1 to be due each class. DO THE PRACTICE PROBLEMS. Not doing them is why I almost failed: lack of studying
Prof. Ograin is one of the clearest and most organized professors in the math department. He never throws curveballs on tests and his homework and exams are all direct applications of what he covers in lectures (not always easy). The class can be a little dry sometimes, but he is genuinely so kind and helpful when needed. Would highly recommend.
This professor knows math and knows how to teach it. I learned so much. It was challenging, but he cares a lot and will help you if you ask. Class was always engaging.
Chris is an excellent professor! Lectures are engaging and fun. He assigns a lot of homework but puts all the same stuff on the exams so no curveballs. I would 100% take his class again.
Chris is the best math Professor at UCSB. He actually cares about his students and is very down to earth. If you put in the work, show him youre putting in the work and go to office hours, then he will pass you regardless of your test scores. His lectures are super engaging. He is by far the best professor at UCSB.
I've had him for a lot of courses: 103, 101A, 102A/B, and ED 130. Amazing teacher! Very dedicated. He really wants you to understand the material. Tells you the type of material that's going to be on the midterm and the final, usually problems from the uncollected homework. Great teacher overall.
