I'm about to be a first-year graduate student and was asked to write a first draft of a calculus one midterm.
I have always used TeXstudio for homework and research papers I have written and they only required the document class "article", but when I tried to write something in the document class "exam" I got the error "File `exam.cls' not found". I downloaded the exam.cls file, but I can't figure out how to install the file so that I can use the exam document class. I've read a few things online, but they didn't make much sense to me. Thank you for your help and patience.
