I like Ograin. He's a good lecturer. He often puts things into common language so it's easy to get what he's saying. Homework load is light. Office hours are worthwhile.

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

I have this professor for 4 of my undergrad classes and so far 2 of my graduate classes. He is easily one of my favorite professors at UCSB. I would definitely recommend taking his courses. He clearly enjoys teaching and is more than willing to go the extra mile to make your experience in his class enjoyable.

Great professor! The exams are very fair and he does a great job at covering all the required content in lectures.

Prof Ograin was great. Very organized class. His lectures were easy to follow and he was always available for questions. No curveballs on exams because he truly tested for understanding of the material. Homework took a while but was helpful to understanding course content. 5 exams worth 75% and 9 webwork sets worth 25%.

Best math prof I have EVER had. He cares a lot about what he's teaching, which makes the students have a love for the subject too. Encourages questions. Class was based on 5 tests, one given every 2 weeks, and weekly webwork problems. Totally handleable and he managed to make it fun. Take him if you can!

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.

Professor Ograin is great, very clear lecturer and let's you know exactly what is expected of you. He allowed me to submit a test late because of a technical difficulty which saved my grade big time. The only downside is Exams are worth 75% of the grade so you have to be sure not to mess up on them.

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.

No Answer for everything, you must be learn by yourself. TOOOOOOOOOOO, Difficult toooooooooo study.

He assigned a book but then would make up his own proofs that were much harder. He couldn't even do his own proofs when we asked him during office hours. Chris is a "nice" guy but makes material much more difficult than need be. Also incredibly harsh grader.
