Every year many students literally get lost on the large campuses. And one campus tour seldom provides the geographic knowledge necessary to get around at a major college. So become an explorer and spend some time learning where all the departments are located. Don't become one of those seniors who is still looking for the library. You can usually find them in the schedule of classes and almost always in a student handbook.
Confusion is one thing but ignorance of a rule says volumes about a person.
Rumors of all types abound on a campus. Almost all have a particle of truth but most have an abundance of fiction. So if you hear a statement which, if followed, could affect your program, check with your professor or your academic adviser. Acting on or putting one's faith in the validity of a rumor could prove embarrassing. This includes having a social life but you must learn to plan your study time properly.
