These factors include author royalties, publisher costs, marketing, publisher and author taxes, and bookstore expenses. Most universities try to offer textbooks to students through their university bookstore at a lower markup. Some universities will buy back textbooks from students at the close of the semester for a portion of the original price. While this is certainly a personal choice for each student, there are a number of benefits to locating employment on campus. On campus employment does not require any form of transportation.
Students can easily walk to and from work if they reside on or close to campus.
Finally, working on campus gives students the opportunity to meet faculty, staff and students on campus. It's a great way to network and build connections on campus. Be sure to stop by your university's student employment office while you're on campus for orientation. You may be able to find a job before the fall semester begins. You will find that most colleges and universities have many resources in place to make their campuses reasonably safe places for the students.
