While I agree with the idea about the experience of being away from home being so valuable, I also see the value of going to community college for the first 2 years. Around here the CC credits seem to transfer with no problem to the SUNYs as well as to the private schools. I know a few kids who wanted to go to private schools, but could not afford it. They therefore started at the CC and then transferred into the private schools their junior year. It worked out well.
I've also seen kids who weren't such good students in HS and sho would therefore have difficulty getting into a 4year school, start with community college and absolutely thrive!
What Pixie said!

Like others have said, it's good to think about it now..take the most challenging classes you can, and get the best grades you can. Also make sure you take three or four years of the the main academic subjects. For some reason I think NJ only requires two years of a foreign language, for example, but most colleges seemed to want three.Good luck!!
Most definetly take language in H.S. for college credit. Our school encourages it from middle school. I know a few kids who are taking it in college now and are sorry they didn't do it earlier because it's alot tougher.
