<p>It doesn't really matter what you major in. I think you would want to major in something with a reasonably large writing component, which English and Theater both have, simply for the practice, but it's not unheard of for people to come from science or technical backgrounds, particularly if that is the kind of journalism they want to get into. I think one of the real benefits to not having a journalism major is that you are forced to gain specialist knowledge in another area which you can, hopefully, eventually apply to your career in journalism.</p>
<p>Before transfering, you should start building a portfolio for yourself. It's never too early to start. While you are still in high school, if you have the opportunity, get involved in your school newspaper, yearbook, anything like that where you can learn about writing and how a publication gets put together. </p>
<p>If you have a local newspaper, approach them, ask if you can come see how journalism works in the real world, how something gets published in their newspaper (I'm assuming you are interested in print journalism), see if you can gradually build that initial contact into something more: a day, a week, a summer, anything you can get to add to your experience. </p>
<p>Also, look for other opportunities to write and get published. If you have a particular area of interest, say arts reviews since you mentioned theater, look for websites or newsletters that might welcome ad hoc reviews of theater performances. Look out for competitions like Teen Ink that can get you used to the idea of putting your work out there for criticism and the possiblity of getting published. You could also have your own blog that you use just for publishing your writing.</p>
<p>Once you are at Bard College at Simon's Rock or wherever you go, find out if they have any student publications and get involved with whichever interests you or, if there aren't any that interest you, start you own. Be willing to do stuff that doesn't sound all that interesting or relevant at first. A lot depends not on how fantastic a writer you are, but whether the editor thinks you are reliable and they can trust you with an assignment, and you have to build that reputation for yourself. Find out if you have any aptitude for things like copy editing too, not just writing, as those additional skills can be a big bonus if you are looking looking for a way into a college newspaper.</p>
<p>Find out about different areas of journalism: what interests you, what publications exist, who the names are in that area and how their careers have progressed; and start thinking about where you might submit articles and what might be required of those articles in terms of research, experience, style, etc. Keep looking for places you might be published right now as well as places that might publish you in the future. </p>
<p>You should also look around for internships, and keep track of the ones that exist and when you have to apply, even if you aren't eligible for them right now. The dates you have to apply for some summer internships are shockingly early! </p>
<p>Academically, take writing classes and do well in them. For some of the writing classes at Yale, you have to apply or get the instructor's permission, so you need to be able to show that your previous classes have prepared you. </p>
<p>Sorry, this is really long. To get back to YJI, basically, when you apply for the seminars, you have to say what experience you already have, both in terms of writing generally and in classes you have taken, what your aims are for the course and long-term, and give them a writing sample. They expect a bit more than "I'm a totally excellent writer and I love Rory Gilmore", so you need to be prepared.</p>
