Harvard College是本科也就是undergraduate,就是列属于Harvard University下面的,申请本科的时候一般是Harvard College。
Harvard University里面还有许多研究生院,这些在一起加上其他行政部门才组成了哈佛大学。然后这个是Harvard自己的网站上的回答可以看看Harvard College offers a four-year undergraduate, liberal arts program for students seeking their first degree - a bachelor's in arts or sciences. There are about 6,500 undergraduates at the College, 50% male and 50% female. The College is only one part of Harvard University, which includes 10 graduate and professional schools, all of which offer programs for students who already hold bachelor's degrees and seek advanced training in their fields through master's or doctoral programs. All 10 graduate schools maintain their own admissions offices and teaching faculties, and they are run independently of Harvard College. For information about Harvard's graduate programs, please contact these schools' admissions offices directly.
