"Shopping" for the Class-But Not Totally at Your PleasureYale has a unique style in her educational system which is known as the "shopping period".It is Yale's course selection period during the first two weeks of classeswhich allows you to participate in courses that interest you without enrolling in them right away.By way of such "shopping period"，you get to know the essence of a subject whose course title sounds attractive;you get to find where your lifelong research interest lies.After you arrive on campus, you choose courses to visit during the course selection period.What's more, in the first five minutes of the class,whenever you feel the lecture is too boring for you to follow,you can leave the classroom at will.Then from those you visit, you will enroll in four or five a semester.Please be aware that classes conducted during the first two weeks of the term are regular, full-fledged classes with readings and homework.Be prepared to keep up with assignments and participate fully in each class that you may wish to visit.However, in order to ensure that study is neither too narrowly focused nor too diffuse，Yale College requires that study be characterized, particularly in the earlier years, by a reasonable diversity of subject matter and approach，and in the later years by concentration in one of the major programs or departments.
