I'm planning to do something scientific. Probably something involving either chemistry or physics, chemical engineering sounds pretty cool. Maybe even a mathematician, I'm finding the trig stuff in my pre-calc class incredibly easy. Alternatively, I could do computer programming. I'd just like to teach myself C++/Java beforehand if I do so.
I have a couple of years to decide though, so I'm not stressing too much.
EDIT: My minor will probably be something totally unrelated unless I need a specific minor for a job I'm looking for. Probably like music related, music theory maybe. If that even qualifies as a minor.
