Anything you want. Preferably something you're interested in. The subject itself is unimportant - the facts you'll be learning will be out of date by the time you graduate almost regardless of the course you pick. The skills you need to learn are self-motivation, self-reliance, working in a team, and how to recognise what's going on around you (in terms of both spotting opportunities and recognising when things are going wrong). You can learn these skills on any course.
