Also include copies of any standardized test results in your file. In addition, if you have ever written an essay about yourself or your goals, include a copy of that too. You should begin the process of finding available scholarships during your Junior year. You can request information from that address at the beginning of your Senior year and they'll send you the appropriate information and applications. In addition to having a friend share information with you, there are a number of other places to look for scholarship information.
Counselors are generally the ones who receive information about new scholarships in the mail.
So check with them periodically to see if there are any new scholarships you should be aware of. Even if you have a very small graduating class, your Counselor can't possibly remember what they've given to each of you. Often Counselors post new information on bulletin boards, print it in newsletters, or read it on the morning announcements. So find out how yours does it. For scholarships specific to your chosen schools, you should use the Representative of Recruiter as a resource.
