Do you think i can get into one of the ivies or good ones?

<p>Ok i'll start off with a bit about myself.
I turned 14 last year in december. I study at the best highschool in singapore. It's a university high school almost equivalent to Bronx. However. my GPA has not been very good. It's a 6 year program and my transcript for the first 2 years was 2.9 out of 5. My first to third semesters were around 2.5 but i decided to buck up last sem and i got a 3.8. I am a mediocre programmer and i was a finalist in a local show called Singapore's Brainiest Kids. I'm a National Education ambassador in my school and i'm in the "Executive Committee".
I'm a part time stock broker and have earned quite a bit.
I'm was selected for the international physics Olympiad and got Distinctions in almost every AMC till date. I'm also taking up SAT prep classes now. </p>

<p>I just wanted to know, if i buck up now, could i get into one of these universties:
John Hopkins, Brown, Stanford, Columbia, University of Chicago, Princeton, Yale or cornell?</p>

<p>Or is it too late?</p>

<p>You seem to be a very talented student. Just raise that GPA and do well in high school. You'll be fine.</p>
