Many people find that the best thing to do is to major in a subject like political science, economics or education, all important coverage areas for newspapers, but to get their journalistic training by taking some journalism courses and working in newsrooms. A journalism degree, with no experience won't take you very far. Visit a college before you select it, and visit more than one. Pay attention to their course offerings, the competitiveness of the school and your feelings about it. It's important to find a place where you can be challenged and successful.
College is a whole lot more than a big high school.
For many people, it means being on their own for the first time, and a lot more personal freedom. College also means a whole community of interests and ideas. Make sure you take full advantage of the opportunities you find on the college campus. Again, think broadly, not narrowly. College publications can be a big help.
