You can apply to both PG year programs and to colleges & universities, then decide when you have received decisions.
You present a strong case for attending a PG year & many elite prep school PG programs will accept you with a 1490 SAT score and an improving academic profile.
No one participating in this thread has the authority to make an admission decision at any PG program.
I have suggested the Lawrenceville School to you as an option for a PG year. Please consider Lawrenceville. If it helps, I know of more than one head of school (prep schools) who have enrolled their sons at Lawrenceville for a PG year with excellent college placement results.
Feel free to contact any and every elite PG program in the country & ask about your situation and about your candidacy for admission and for enhanced college options.
P.S. Varsity lacrosse. As a varsity lacrosse player, you are a student-athlete. I do not recall ever knowing of a better case for a PG year at an elite program than yours–although I know many who were required to attend a PG year in order to qualify for admission to the US Naval Academy.
P.P.S. I suggest that you consider PG year programs at:
The Lawrenceville School & Deerfield Academy
Others to consider / contact: Loomis Chaffee, Choate Rosemary Hall, The Hill School, Kent School, Mercersburg Academy, The Peddie School, Phillips Exeter Academy, & Phillips Academy-Andover.
Other PG programs that might be of interest: Hotchkiss School, The Taft School, McCallie School (all boys), Northfield Mount Herman, Wyoming Seminary (athletic powerhouse in several sports), Blair Academy, & IMG Academy for athletics.
