Reviews
I had Ouyang last spring for real analysis and I loved him. He is very good at explaining things and cares about his students. The class is hard but he makes sure you walk away with a good grade.

Super hard, but very rewarding. The first proof base class I took after 310. It is very achievable to get a good grade, but definitely takes time. Highly recommend. \n\nOuyang was solid. He gets too much criticism.

Alan is incredibly nice. Both his love of math and smile are infectious. His lectures are very well-prepared, and they certainly helped me intuit analysis. As is to be expected, 4111 takes time and persistence, but Alan is an excellent prof to take it with.

Very hard class but learned a lot. Be prepared to study and spend time reading the textbook.

Most disorganized and confusing class I have ever taken. Didn't seem to prepare lecture materials before class, frequently said contradictory statements concerning the syllabus, and gave incoherent proofs and explanations. Extremely disappointed with the complete lack of structure in the class. Had to self learn the entire course.

Professor Stern is fantastic! His lectures are fast but easy to follow and delivered with enthusiasm. Don't be afraid to ask questions during class. He is tremendously helpful in office hours, too. So if you are stumped on a homework problem - and you will be - show up and he will clear up anything that's puzzling you. And he's a metalhead \m/ !

It's a tough subject, and Prof Wick is exactly the kind of teacher you want for it- he's incredibly prepared, precise, and thorough. Very very helpful in office hours- no question is too dumb. Homeworks are big and take a very long time, and there are many exams, but the problems on them are very fair. Got a great grasp of the material from him.

He did a very good job explaining the concepts with examples. He has a hight expectation, but he won't trick us on the exams: everything is from lecture or homework, and most of the final is from previous exams. However, he is not accommodating individuals and we had both a midterm and a cumulative final at the end of semester, which is a lot.

Brian Blank is a mess. His lectures are all over the place, he didn't use a textbook, and his exams were unfocused and unrelated to class. His grading can be lenient at times, but taking a class with Blank is the ultimate toss-up. Funny and sweet guy, but overall don't recommend.

sooo good !!! He is the best teacher I have ever had. Just make sure you studies after class .

A very sweet man. Sure, he covers twelve semesters' worth of material in a single class. Sure, his tests are so ridiculous that 40/100 curves to a B. And sure, you'll be pulling all-nighters on a weekly basis in order to get any homework points at all. But he wants to help you, and he wants you to succeed-- so go to office hours and it'll be okay.
