Oh yeah we're on the same page that taking classes in a different, specific topic is a great way to amplify your existing CS skills. I'm mostly making the point that going into college with the mindset of double major or bust can be counterproductive. The difference between a minor and a major can be a few extraneous courses, a lot more stress and a little less time to pursue your main interest.

I know I came into college determined to do a double major only to realize that I probably should have made that decision after taking a few courses and evaluating my level of interest in the two subjects.
