Computer Science versus Spanish for the Professions Minor

I am completely sure that I want to go into investment banking. I am going to enter my Freshman year at UNC Chapel Hill and am choosing what route I would like to take. I will major in Finance and Economics, and am not sure whether a computer science minor or spanish for the professions minor would be better. I have some prior computer science knowledge as I have taken two courses at my home high school and am interested in it. I also am interested in spanish and will not have to take any introductory spanish courses, only 6 required for the minor since I am already very knowledgeable in the subject.

Based on this, woul a Compsci or Spanish Professions minor be better with my Finance and Economics major?
Also, any other tips for getting my foot in the door in IB from UNC Chapel Hill as early as possible is appreciated.

I would say both are very useful knowledge. If you are fairly fluent in spanish, I would say CS.

D1 is in trading and she had a minor in IT. I believed it helped her.

Other advice? Get as high GPA as you can (3.5 or better would be good). Get involved with things besides classes. Join clubs, do volunteer work, etc.
