What is your PSAT, and equivalent SAT? Also, what state do you reside in?
Your PSAT, and equivalent SAT, can certainly under project how you will actually perform, especially given you will have another year+ of high school under your belt when you take the SAT. You also have the opportunity to take SAT study courses which can significantly boost your scores 200+ points in a few months of study.
For reference my son scored a 1040 on the PSAT (550 math, 490 ebrw), which has a 1170 SAT equivalence. Yet he achieved a composite 1360 SAT score (690 math, 670 ebrw), from 1310 and 1340 individual tests, and that was without any study.
I have no doubt had he taken Khan academy or other SAT prep he would have scored 1500. Unfortunately, I found out too late the SAT review class offered by his high school did little to prep and instead was used as study hall by nearly all students.
