CMU ED-by Current Junior PLS HELP!!!!****

Hi all,
my ultimate goal is CMU, and I’m looking forward to do ED next year. Major: mechanical engineering
My current situation:
I am a female asian student.
I’m taking AP Calc BC, AP Physics 1, otherwise all regular classes.
GPA is around 3.3 out of 4 which is not good… my science and math classes are a hard core.
school ranking is high enough, #600 or something I don’t remember
Next year, I am going to do Stanford math program, AP Stat, AP Physics C, AP Comp Sci (maybe), etc…
I took my SAT: i might take it again and get a better score…(new) 1520 and 21/24essay
SAT 2s: math 800, physics:lets say it will be close to 800, chem:780
Extra activities…I do not have a lot.
internships: for a community, hospital,
awards: AMC10 top scorer of school, will pass AMC 12 this year!!I believe, many from debate, poetry stuffs, school math league awards
Thanks for reading this, and I am looking forward to see great advices! Thank you so much!!!
