The Kardashians have been so famous for so long that it's hard to imagine that they were ever just regular people. In truth, they weren't - all the children were both into vast wealth - but they still had to go through education just like the rest of us. In Kourtney's case, she split her time between two universities, studying theater arts, with an additional minor in Spanish. She's never really had to make use of either qualification.
She doesn't sound like she actually had the best of times during her college years. She was stung by a scorpion, which is a pretty painful experience, and actually failed two classes because she was too nervous to stand up and give speeches in front of her classmates. Given what she does now, with her reality television shows and prominent social media presence, she definitely got past her shyness at some point!
