@Troyus With 3+2 programs (including Oberlin’s) students get two BS degrees – one in the liberal arts course of study from the first college and one in engineering from the second college. This is a dual degree program. No Masters degree is earned.
From Oberlin’s website:
“In the (3+2 Engineering) program, students pursue studies in the liberal arts, including mathematics and sciences, during three years at Oberlin and then complete an accredited schedule of engineering courses during two years at an affiliated engineering school. At the end of five years, students receive two degrees: a Bachelor of Arts from Oberlin and a Bachelor of Science in Engineering from the engineering school.”
