Chances of getting into BYU

I am a junior and I am applying to college at BYU nexy year.
I have a 3.7 UW and a 1250 on the Sat(plan on getting it to 1400). I had a 3.1 freshman year UW, 3.92 sophmore year UW, and a 3.9 UW junior year. I am in some honors but not all.

Extra curriculars: volunteer for a cat adoption center, eagle scout, piano (certificate of merit level 5), volleyball, job
What are my chances of getting in with a 3.7 and a 1400 SAT, considering my bad freshman grades
