Currently taking 4B. Midterms were very similar to the practice midterms given. One thing I will say is I didn't understand his lectures, so I just went to CLAS, and it helped tremendously. Not too, bad, exams were pretty easy I have a 90 in the class currently. 85% is an A- in this class. I have the final tomorrow so wish me luck! :)
Don't do it. I have him for Math 3B and exams are extremely off from practice and he is difficult to understand and takes a long time explaining things that dont need to be explained for that long.
