Please Evaluate My HS Plan? I'm Looking to Get into an Ivy league university.?

Hey Guys, I go to a public high school and I really want to go to a top-notch school, and as of now I'm looking at the Ivy League as well as Stanford University. I'm a sophmore and my classes are as follows:

10th Grade:

HNS Chemistry

HNS Algebra II Advanced

HNS LA II

HNS American History

Graphic Comp Apps

Spanish 4 (One year advanced)

Gym

Study Hall

11th Grade:

AP Calculus AB

AP US History

Spanish 5

AP Chemistry

AP Language Arts

AP European History

Gym

AP Physics

12th Grade:

Journalism

Multivariable Calculus HNS

AP Biology

AP Language Arts

Princeton University program in Chemistry or History, where I take courses at PU instead of at HS

AP Spanish

Gym

Independent Research in Science (actual class where we do independent research with a supervisor)

So yeah those are my classes.

Here are my activities:

Varsity Cross Country

Will be creating a Non-Profit organization really soon (in a week or so) that will be international

On the Fencing team as well as the Track Team

Volunteering at local hospital, hoping to get accepted into the internship where they let you watch surgeries

Internship (hopefully) at a congressperson's office

NHD Member as well as MUN member as well as Robotics Member

Karate Black Belt

I'm pretty sure I need more as well and I'm still looking for great oppurtunities, but as of now, is my HS plan as well as my activites plan good enough to get into an Ivy League school?

Also, I'm a sophmore currently and I have a 3.8 GPA so far and I consistently get SAT scores between 1950-2050 right now, and that will defintely improve by my Junior year! Thanks!!!!!!!!!!!!
