    If you have the right professor, this class can be incredibly interesting and expand your view as to what math is. Regardless, it is still one of the hardest math courses I have ever taken. Highly recommend, especially if you are considering a math major/minor.

    Hardest class I took at Duke! The reason I am not a math major. DONT TAKE unless you love suffering.

    This is a tough class - especially if you have never had a formal proof based course. Linear is the gateway course to all math classes and is graded traditionally (homework, 2-3 midterms, and a final). Get ready for many proofs - definitely do not recommend unless you want to major in math.
