Seems like the only thing for the rest of this school year, beside school, for her to do in terms of college planning is to take the SAT and/or ACT. Even that is not strictly necessary this school year, but is desirable in terms having time for a retake in senior year if desired and getting an earlier idea of which colleges are realistic for admissions and scholarships.
As the guardians, you can look into the cost and financial aid situation.
No need to push hard on the college front now.
