Lucky you guys, I began wondering what course I want to do at 15, as I have/had to make a decision at 16. Definitely agree with it, it's too early, but what can you do to change it? The pressure to go to university at the earliest and have a good degree that comes from parents and other outside sources is high, and there's very little you can do to change it. The best way is to take a year out after school, work part-time/full-time for a while, save up money, and do something on the side - If you think about computer science, try programming, see if you like it. Interested in History, try writing an essay about a topic you like, etc. Even still, there's no way of telling if you'll like your degree unless you try it, whether you start at 18 or 30, it's just a risk you have to take.
