Percentiles

What percentile ranks are considered good? I scored 1950 on the october SAT, but I’m above 90% in all sections… Is that good?

“good” depends on the competitiveness of the college. Google the 25th-75th percentile range of the college’s SAT/ACT scores.

I already know about that, but how do I interpret the percentile ranks of the SAT?

Just as @GMTplus7 said, it depends on the school. Of course being in the top 10% of students is good. It’s not good enough for HYPS.
