I had Professor Oberlin for 115A. 115A is kind of the standard first upper division math class that most people take. I would strongly recommended Prof. Oberlin for this class and other upper divisions if possible. I do not know about his teaching in lower div. classes so I can't speak for that.

He presented the material in a straightforward, but organized way. He moved pretty fast and covered a lot in a class but he also had 3 office hours a week so if you had questions, you could go to those. 115A also meets 5 times a week (2 discussions) so there is a lot of help available which is good. One thing I liked about Oberlin was that since the class does emphasize proof writing, he did an intro to proof by contradiction/contrapositive and induction. It was not too thorough but it was pretty good.

His first midterm (I am currently in the class) was really fair. I thought the average would be really high but it turned out to only be 50%. If you are able to do the homework problems and such, you should be good. He does definitely emphasize proofs on his tests, as should be the case in 115A (33A is the more computational side of Linear Algebra). The proofs on the test are doable though. I obviously liked Oberlin since I am taking him again next quarter. He is a good professor- maybe a little less talkative/personal in his OHs than other professor but a cool guy too.

After taking Oberlin's class for Math 33B, it's pretty obvious he's a 3 series professor (no offense to those who take the 3 series). His tests were extremely easy (averages ranged between 85% to 95%), and all of the tests are pretty much straightforward. If you're taking him for the Math 31,32,33 series, be prepared for an extremely high average.

1. The 2 midterms were EXACTLY like the homework. Do the homework, and you'll do well on the midterms
2. Lecture could get a little confusing because he moves pretty fast through the material. Ask him a question to slow him down
3. The beginning integration material is what most of the course is, and since it's really easy, it put the class average really high. When we got into multivariable calc, you could tell everyone was getting confused, and this is what might have changed the class average, because half the final was on multivariable calc

That being said, this was the class I was least worried about, because if you do the homework and understand it, you'll do well in the class. Oh, also, my TA(Sherwood) was AMAZING. If you have any questions, ask your TAs during discussion. I also recommend taking a Thursday discussion, because homework is due Fridays, and by Thursday you should have your questions prepared.

He is not the best math professor you're going to have, but then again, it's tough to find good math professors. He spends a lot of his time proving an equation that you're going to use rather than just giving you the equation. You don't necessarily have to go to lecture to get the material; you can read the textbook. Make sure you do all the homework though because that really helps and homework also counts 10%. The class must have been pretty easy for majority of the people because the averages were usually pretty high, especially for the midterms. He gives 2 midterms and one final. Midterms both worth 25% each and the final worth 40%. The final was definitely more difficult than the midterms, but still, the class did pretty damn well. 80-89% range. So my suggestion would be to do the homework and extra homework problems if you need it and you should be fine.

Pretty easy professor.
Clear, coherent speech.
Just do the homework, attend lectures and understand all the concepts and it should be a fairly easy class.
I really liked professor Oberlin.
Only drawback: He doesn't do the best job explaining some of the more difficult concepts.

He's a pretty chill professor. The class didn't get difficult until about half way through when you start modeling populations and doing multivariable. His lectures were often confusing, but after doing the homework they usually made sense. Tests weren't terribly difficult, but (besides the first midterm) weren't terribly easy, either.

His classes are very easy. I got an A on the first two midterms and a B on the final and an A in the class overall. His tests are straightforward.

He takes some getting used to. The beginning of the class is easy, if you took AP Calculus, regardless if it was AB or BC. His tests are fair, and the class always does well. He does a lot of proofs, most of which are superfluous, since all you need is the formula. Go to lecture, pay attention in lecture, do the homework. He's really chill, which isn't all that good when he's explaining a concept, but a good TA will clarify it up. He won't screw you with the curve, which is a definite plus.

Worst math professor I have ever had. He does not teach, do NOT take him if you do not already know everything in Math 3B. He was simply awful, and Richardson is much better. Oberlin is horrible.

After AP Calc AB, this class was fine. Easy first midterm (basic integration), and then got a little tougher, but most people stayed in the A range. Chill guy, but he knows his stuff
