I am an undergrad Junior studying ISyE and I am trying to decide which class to take next semester, Quality Control (Statistical Quality Control) or Linear Algebra. I have already taken two courses on Linear Algebra, but this is a bit more advanced class. I want to pursue a MFE program for my graduate studies. Which class would be more beneficial to me? Is Linear Algebra used extensively enough in MFE for me to take another class? Both classes can be used as an elective for my major. Thanks.
