Graduate school encompasses courses in fields of study as different as a Ph.D. in Molecular Biology, a Master of Social Work (M.S.W.), a Master of Business Administration (M.B.A.), a J.D., or an M.D., among many others. The thing to keep in mind about graduate study is that it is more technical and specific than undergraduate schooling,and it sometimes combines academic and practical training. Professional masters degrees, like the M.B.A. or the M.S.W., are practical degrees that prepare students for specific career paths. Their curricula are often multi-disciplinary and can include semester- and year-long practica.
