chances at MIT / stanford SCEA?

<p>hi! I'm an international student from southeast asia and plan on doing engineering, preferably electrical or mechatronic, not sure yet though. 1)MIT,2) Stanford and 3)Princeton are my top priorities and since MIT has no early action option for intl's so I'm thinking about applying to Stanford SCEA but the prob is that Stanford is not need blind for internationals and I'll be needing some FA.
I'm a 16yr old female and i'll be 16 when i apply , will that in any way be an advantage or disadvantage for me?
i did O'levels and had 5A* and 3A's , A* in maths, phy , chem n bio
I'm currently doing a'levels in maths, phy, chem n bio.
they don't rank here but im in top 5% of my class
SAT1 and 2 I'll give in Oct/nov.(sat2 in maths 2 n probably phy)
the prob is that i lack somewhat in my extracurricular.
please tell me if i should apply SCEA to Stanford or Princeton? any suggestions and comments will be appreciated ! thnx!</p>
