This brochure is written for students considering graduate work in physics or related fields such as astronomy, biophysics, and applied physics. It also provides some information for physics undergraduates who plan on pursuing postbaccalaureate studies in the fields of engineering, medicine, law, and other professions that attract significant numbers of physics B.A./B.S. graduates. It is designed to help students decide whether to pursue a graduate degree and, if so, how to prepare for this path while still an undergraduate. It addresses the mechanics of the application process, the types of financial aid, and the final selection of a graduate school. It concludes with a discussion about what a student might expect during the first few weeks of graduate school, and an example of a personal timetable.
