I’ll second Comsolation’s advice. If your son is interested in writing but not committed, then he should consider majoring in whatever he is interested in (political science, history, economics, environmental science) and get his writing experience by working on school media and internships. So when considering colleges, check out their newspapers and magazines – how often do they come out? Can anyone write for them? Are they independent or controlled by school administration? Many college newspapers have a regular email that goes out with links to articles – sign up for that.
