<p>Thanks for providing more info 
I think you have some decent stats. If you are considering applying to the big name schools, I would consider changing your major. If you are interested in acting, why not major in music or theater? A girl from my school with average stats got accepted into Yale above the class valedictorian (also a nationally ranked swimmer with 17 AP courses) because her major was in music.
I would also try to take more AP classes if you can. If you can’t, self-study and take the exams. You should try to take at least 5 next year for a chance at the ivies.
I hope this was somewhat helpful! :)</p>
