Chances of Getting into Texas A&M University

ok so i’m a junior in high school and currently in the top 25% of my class. My SAT score was a 1500 but plan on retaking it. my goal SAT score is a 1700 and since i take an SAT class its not out of reach. I plan on applying this summer and hopefully my class rank will rise by the end of my second semester.

I know that I’m far from a shoe in and my math SAT score is highly lacking(510) but my critical reading score is pretty high and writing(I know they don’t look at it) but what are somethings to I guess work on before applying and how much will applying as soon as applications open up increase my chances.
