Spring 2020 - James was incredibly understanding this past quarter and really worked with the students to make sure our needs were met. If we were struggling, he would add additionally office hours and he even made adjustments to the grading scheme. Overall, even though this class was challenging and unclear at times, it was a great experience and James is a good professor. If you are willing to engage, you will get a lot out of his class.
Winter 2019 - Uh this professor doesn't know jack and can only recite definitions from the textbook, but expects us to do proofs... so tldr don't take him unless you understand the material already because the textbook isn't clear and the professor doesn't teach. Also, if your TA is Ben, be ready to ask a question and then have take an hour to work it out with you by asking YOU how to do each step, which you most likely won't know how to do because you're asking the TA the question.... TLDR: don't take this prof and go to another TA other than ben :)
Winter 2019 - I am writing for a friend who doesn't have a bwalk account here. From his experience in 115, this professor can hardly teach and my friend selfstudied almost everything. I took math 61 with him, and it was just as terrible, if not even worse. NEVER TAKE A CLASS WITH JAMES CAMERON. IT IS A WASTE OF YOUR TIME AND MONEY.
Fall 2020 - Prof. Cameron was decent. Math 131A is known to be one of the toughest math classes, so much of my difficulty was with the topics rather than him as a professor. He is kind, fair in his exams, and really does try his best to be helpful in his lectures, although I always felt a bit confused. He definitely knows his stuff, just has a hard time conveying that knowledge in a way that students can understand. Reading the textbook was helpful to supplement his lectures. I think taking the class online is what saved my grade, so I can’t say what he's like in person. Would I recommend him for 131A? No. However, it won’t be the end of the world. Be prepared to put in the work on your end. Assignments consisted of doable but challenging weekly HW, 2 midterms, and a final exam; as most math class are.
