Choosing math courses is one of the most important aspects of being a math major, though these choices are often quite difficult. Upon entering Princeton, many math majors do not know which areas of math to explore. Even for those who have decided this question, it is often not apparent which courses to take and in what order. Moreover, there are always questions of which courses it is feasible to take simultaneously, which courses overlap in material covered, what knowledge does one need before taking a course, and many others.
The goal of this course guide is to provide information to help math majors make these decisions. Before this course guide was compiled, the available sources of information were the registrar's Course Offerings and the math department's undergraduate courses page. These two are important information sources, and every math major should consult them. This course guide supplements these sources by bringing in the student's perspective. All of the information presented here is taken from the experiences math majors have had taking these courses.
