    | No strong feelings either way.

    Not too easy. Not too difficult.

    Course Overview:

    at the time, the material seemed very hard but after finishing the class and still using the concepts, they seem easier and are obviously very useful

    Course highlights:

    lectures were not very useful to go to but clas was very helpful and webwork helped to master concepts

    Hours per week:

    6-8 hours

    Advice for students:

    there is longf homework so be prepared to put time into it. not too many problems but the problems are very long and time consuming. no practice midterm or final

    | No strong feelings either way.

    Not too easy. Not too difficult.

    Course Overview:

    I felt indifferent about this class because it was one that I had to take for my major. It wasn't too difficult, but my professor especially was very hard to understand. I recommend going to office hours or enrolling in CLAS.

    Course highlights:

    This course was titled Linear Algebra, so it was a lot of simple computations, functions, and matrices.

    Hours per week:

    3-5 hours

    Advice for students:

    You do have to work hard for this class, but you shouldn't stress about it too much. If you pay attention to lecture or receive outside help, you will succeed.

    | Probably wouldn’t recommend.

    Not too easy. Not too difficult.

    Course Overview:

    lectures didn't help and the midterm was very difficult. a lot of the homework didn't correspond to the lectures

    Course highlights:

    going to section helped to understand what was going on and how to answer the homework problems

    Hours per week:

    6-8 hours

    Advice for students:

    know how to do the homework by hand, even though you can find matrix calculators for most of the problems
