I took his classes 20 years ago, I went on to get my PhD and he is one of the best math teachers I ever had. If you are a good student and want to learn and go further in math he is likely still the best instructor on campus. His classes are difficult only because he pushes his students to really understand what they are doing.

I took this class on the recommendation of my Calc I professor, who said Dr. Lax was good. And he is good, but he goes very fast -- he seems to assume that you can understand everything he says. His tests are difficult, at least one level above any of the homework. Average grade in my class was 40 out of 100. I struggled just to get a C (60/100).

Hard tests. If you know the hw, the tests are just with a lot uglier and annoying numbers to deal with than the hw. Ask ANY KIND OF QUESTION YOU WANT ABOUT THE EXAM the class before, and he will answer it in front of everyone so it's fair (will not do this in OH). You can even ask things like "will we have to know pg.795 question 23 for the exam?"

During review sessions, make sure to ask a breadth of questions instead of all parts(e.g a-g) of one problem to make the most of the time he provides.
