Also, the Rutgers Business School excels in finance and accounting. About 75% of the students that graduate from the school accepted jobs in those areas. The tuition at Rutgers will be the cheapest of the three as well (assuming you're from NJ). It's a smart investment.
Also, just to give you an idea of how competitive the Rutgers Business School is becoming: only 400 of the 8,000 applicants to the school this past year were accepted into the program straight from high school. It's very tough to get into and the students that are admitted are top notch.
The future of the Rutgers Business program is only getting brighter as well. New buildings will be constructed in the coming years and donations to the school have increased steadily (the business school received a $10 million donation this past summer. It was the first in a series of donations that are forthcoming).
