Say what you will about the Kardashian sisters, but the reality stars and fashion/beauty entrepreneurs definitely have keen minds for business. What’s even more remarkable is that they did it without any formal education in business, finance, or management. In fact, just one of the sisters — Kourtney Kardashian — has earned a bachelor’s degree.

Wetpaint Entertainment checked in with Viggle LIVE! users during the most recent episode of Keeping Up With the Kardashians to see how well they knew their Kardashians herstory. Turns out, most of them get an A-plus! The majority — nearly 87 percent, were well aware that Kourtney is the egghead of the bunch. Meanwhile, just under 11 percent thought street-smart Khloe was the college graduate, while only 3 percent thought Kim had earned her degree.

Kourtney first attended Southern Methodist University in Dallas, Texas, before transferring to the University of Arizona two years later. With a major in Theater Arts and a minor in Spanish, Kourt earned her Bachelor of Arts another two years later. As it happens, Kourtney’s focus on costume design proved quite valuable as she and her sisters embarked on their own line of fashions for women, and now, their new children’s clothing line.
