Columbia University Columbia University is one of the toughest universities to get into in the U.S. Coursework at Columbia University is challenging, most notably in a number of required courses within the core curriculum. The core accounts for 90 percent of the work here. Without it, Columbia would be a breeze. The University is teeming with tremendous intellectual activity in just about any field imaginable, and accomplished scholars with mind-boggling brainpower can be found in nearly every department if they are available~ Columbia is a haven for the self-motivated. No one is going to hold your hand. Though students say their school is run pretty efficiently, many students see considerable room for improvement. The administration sometimes restricts you instead of helping you, as one student put it. The library and research resources are poorly lit but truly dazzling. Almost half of Columbia’s graduates enter some type of professional school within a year and one in four graduates becomes a lawyer. Columbia offers and Ivy League education in the heart of wonderfully diverse New York City, the greatest city in the world. Students take full advantage of the benefits of their location, especially on the weekends. Life for Columbia students doesn’t revolve around Columbia, thus the campus is often dead and lifeless. First-year students are required to live on campus, where there is strict alcohol policy and food services need improvement. While many students are completely satisfied with campus housing options, others view the dorms as rat-and-roach-infested closets. Yale University Yale University is truly one of America’s great universities. As a major national research center, Yale attracts many of the world’s great scholars. But unlike other research institutes, Yale also devotes a lot of attention to undergraduates, The professors here enjoy teaching, and the students do learn a lot in classes. However, students complain that too many classes at all levels are taught by TAs and that they occasionally encounter professors who are poor teachers. Conflict on campus over TAs’ demands for higher wages and union representation has also been a cause of concern, heated debate, high anxiety, and student anger at the administration. Academic departments are all excellent here. Among the school’s many fine departments, standouts, include drama, English, history, and the premedical program. Yale has no core curriculum, instead requiring students to complete a broad range of general education requirement. Students say they like the "shopping period" registration system: they don’t formally register for classes until two weeks into the semester, so the likelihood of getting stuck with a lousy class is minimized. It would be foolish to pass up a chance to attend Yale University for just about any reason, provided you can deal with New Haven. Yale students have survived there for centuries, but they are not thrilled about it. Yalies give their home city extremely low marks. Yale’s worst problem is New Haven. It is dangerous and unreceptive to students. Life on and immediately around campus is great, but otherwise it’s a real problem. Michigan State University Michigan State University is a large university, which leads necessarily to some lack of personal attention. There are even six classes taught via television. TAs play a large role on campus because large lecture classes exist for most introductroy subjects. Students here have a wide range of majors to choose from — over 150, and if you don’t find a major you like, you can design your own. Michigan State University also has extensive international connections and offers the opportunity to study at seventy-six universities around the world. The students enjoy the contact they have with the professors. The administration is helpful and hardworking. Michigan State University is located in East Lansing, a good college town. Almost half the students live in college housing, and Greek life is strong here. The annual spring concert and Greek Week are especially popular events. As in any very large school, there is a diversity of opinions as to what makes up Michigan State University life. Some students enjoy it for its academic rigor. Others note the fanatical frenzy of the sports program, and student spirit for the Michigan State Spartans. Over 45 percent of Michigan State University students participate in intramural sports.
