To search for a college, go here: http://nces.ed.gov/collegenavigator/ You can filter colleges by region, by speciality, mission, SAT scores and lots and lots of other things. You can also go here to look at how much a college really costs. Colleges have sticker prices, and then they have the real price, which is the sticker price less grants, scholarships and loans and things. Places like Princeton may have very high prices—50K per year or so, but no one pays it, because anyone who can get into Princeton also qualifies for scholarships that pay the whole freight.
What you do is you decide what kind of school you want. Like my daughter wants a small, rural liberal arts school in New England that is not too close to her grand parents. We, of course, would rather see her go to Harvard than Bennington, since Harvard (which is not rural) is practically free if you can get in, but Bennington costs more than any other school in the country and doesn’t offer much in the way of scholarships, I think.
If you want a good program for some arcane subject, like maybe dance or conducting or social architecture or whatever, you can look for those schools, wherever they may be.
So you sort through the schools, identify twenty or so you are interested in, and then go visit the top five or ten on your list. Go during the school year so you can attend classes. Get a feel for each school, and then apply to your top schools, including the ones you really want to get into and also a “safe” school which is a school you are pretty certain you will get into.
You apply, and see what happens. Then you get an acceptance, and you wait for your financial aid package to see how much each school will cost you, and then you decide where to go. If you don’t like it, you can always transfer. Or quit for a year and find another place that is better. Nothing is written in stone, and if you leave a college, that is not a failure. It just means it wasn’t for you.
Have fun and good luck.
