This is precisely why I'm glad I was able to choose (Management) Information Systems instead of Computer Science for my major. There are key courses in CS that I missed, but I feel like I also avoided a good number of courses (deeper math, specifically) that I ultimately never needed to establish my career in Web development. I've picked up the rest learning as I go.

Being able to get 1.5 years' experience in paid internships when I was at Drexel was also hugely valuable towards kick-starting my post-college career without adding additional classes.
