After one year at the University of Pittsburgh, Cuban transferred to Indiana University in Bloomington, Indiana, where he graduated from the Kelley School of Business in 1981 with a Bachelor of Science degree in management. He chose Indiana's Kelley School of Business without even visiting the campus because it "had the least expensive tuition of all the business schools on the top 10 list".
