Could your friend get the student an SAT prep book if the student can't afford one herself?
If she hasn't already, the student should sign up for the SAT Question of the Day on the college board website. She should take some practice tests and go over them before the fall test date. Getting familiar with the test will help her do her best. Maybe your friend could help her with test prep--organizing a schedule, going over missed questions? Maybe she could help the student identify schools that would be budget friendly--including the local community college-- and show her how to look up the application info./requirements/deadlines, etc. on their websites.
The student should still talk to the high school counselors--at least they could give her an idea of the colleges that other students with her stats are applying to or have been admitted to in the past. The student may have classmates whose parents and older siblings have gone to college who may be able to help her through the process, too.
