Rising Junior- Help!!??

The idea of college has always been on my mind, but now that I am a rising junior, college is starting to become more real. I would love to attend colleges like Duke or Vassar ( and much more ) but, I need to know if I am on the right track and also if there are any people who would want to leave helpful advise that would be very appreciated!

gpa:4.3125
act/sat: haven’t taken it yet
psat: 1340
AP’s: 10th grade Human Geography
11th grade ( this upcoming year) Statistics, US History, English, Psychology
Extracurriculars: President of the Leo Club
founder of a library project to deliver books to children in Africa
varsity tennis- captain
editor and chief of the yearbook committee
youth catechist- head teacher

I know I can get my sat/act scores above a 1400/30 if I study very hard, which I will, but is there anything at all I should work on or is there any helpful advise I can use to help me get through the college application process? Thank you all!

What’s your UW GPA? And you need to get that SAT above 1500 if you are aiming for something like Duke.

UW GPA is a 3.9 . I’ll make sure to work on getting my SAT score higher
