You can narrow the choices down in various way, by the schools academic success, if a school offers the right course or program for you or the financial costs of attending (each university as a different price on their tuition).

You could narrow them down even further if you have a location in mind, perhaps there are certain States you wish to be in or preferred climates or maybe you even wish to be close to the ocean or mountains. Then look to see which Universities are in those States.

However you decide to do it is entirely up to you. If you want an overview of Universities, Business schools, Medical schools and Law schools then http://www.princetonreview.com/home.asp is a good place to start.

There are also other links and information on the following website.
