I took the august 2018 SAT as an incoming junior and got a 1540 (740 R&W 800 Math) but i only got a 5/4/6 essay score. Is it worth it for me to retake the SAT after I take AP Lang and improve my writing skills just to raise my essay score?
No. Move on. The number of colleges requiring the essay is dropping like flies, in part because they can better assess your writing through your essays.So spend time on those.
No. Don’t retake it. You are fine.
