Don't forget your school's career center, if you have one. Usually if they know what major you're going to get into, they'll keep an eye out for you. Plus, colleges will visit your school usually at the career center, tell you about their schools, what scholarships, grants, etc... they're offering. So if your school has one, get acquainted with it asap. Also, please put your guidance counselor into some use.
Yes. Don't forget the fafsa which isn't only based on financial need, but it's also an application towards any scholarship or grants your college may be offering. That's what I did and just looked through the schools who gave me the best package and whether they were my top choices or not.
