What are my chances of getting into Texas A&M

I am currently a senior, ranked 89/556 (top 16%) (91 GPA/ 3.75) With an 1800 old SAT, 1270 New SAT and a 28 (27 English 28 math 31 reading) on the ACT. I am involved in Math and Science UIL, Varsity tennis since freshman year, Was in top band all the way until Junior year. I have around 10 hours of volunteer service ( should I make the effort of getting more hours?), I am a part of NHS and National French Honor Society. I am also a part of Nimitz Academic Decathlon.
I have dedicated a lot of time into my application and have made, what I believe are good essays (well topic A and B). Should I make topic essay C?
Thank you guys, it’d be appreciated to see what people think.

I am applying for an applied mathematics BS and Computer science second choice.
