Target Audience for College magazine

My target audience has the demographic of about 16-19 year olds because that is the average age in which people attend College. The S.E.G for my Magazine will be class E because students are classed as that because they won't usually be earning a lot of money. The Phycographics of my Magazine is achievers because people that go to College want to achieve A Levels and my Magazine as well as letting them know whats going on will help them achieve that.
