If you have the slightest idea what you might want to major in when you get to college, try this:
1. Pick five colleges you're interested in.
2. Go to their websites and find the listing of required classes for your intended major.
3. Read the descriptions of the required courses.
What are you actually going to be learning? Who's going to be teaching you? What does the department for your major claim that you'll gain from that course of study? And most importantly, how does all of that sound to you?
If you're not excited to start those classes as soon as possible, you might want to think about choosing a different major. Or you may need different colleges.
