Wharton is strong
across the board, including in Marketing. The glitzy finance jobs (IB, hedge funds, private equity, etc.) have recently gotten all of the attention in high-school-student-focused places like College Confidential

, but Wharton has been a national and international powerhouse in fields like Marketing, Management, Real Estate, Entrepreneurship, Accounting, and Insurance for
many decades, if not more than
a century.
For example, at the MBA level (essentially the same professors and courses that would be encountered by a Wharton undergrad), Wharton's Marketing program is ranked #2 in the country by US News:
Best Marketing Programs | Top Business Schools | US News Best Graduate Schools
And, Wharton has "the largest, most cited, and most published marketing faculty in the world":

In fact, Wharton has the largest, most cited, and most published business school faculty in the world, period.
You can't go wrong at Wharton no matter what your interests in business. At the undergraduate level, it's simply unparalleled anywhere in the world. And again, that's
across the board, and
not just in Finance.
