Sfs question

If you have a high sat for the given percentile (1560 for cr+math) but a mediocre gpa (3.7) in a competitive high school with most rigorous course load (which doesn’t rank) do you have an okay chance at sfs?

I got into SFS with a 3.7 and a 35, but I had a lot of extracurriculars and probably had to have a stronger essay than others
