Collegeboard will help you with all the tests and some scholarships. Collegeweeklive will help you with finding the right college for you. They have live chats with people who attend the colleges you're interested in. I used several others too but i cant think of their names. Don't go completely off of whats online though. I recommend going to the colleges yourself and taking tours. The college I'm attending now didn't even show up on the websites I was using, i found it myself.
yeah collegeboard is the best site to do alot with college planning.
