Dunno what your story is, but I couldn’t handle Math 2F (multivariable calculus) so I switched from EECS. :p
I graduated in ’89, the last year before it became its own department. So my diploma actually says “BA in Psychology (Cognitive Science)”. I seriously considered delaying one quarter so I could graduate with a BA in the new Cognitive Science department but I wanted to get on with my life. In the end it mattered little.
