American universities for an IGCSE student

[malak6]

Hi, I am an IGCSE student from the Middle East and I am planning on applying to some American universities including MIT, CalTech, and other UCS. My grades are great , I have taken 8 O levels and completed 2 Alevels. Ive got stars on all of them, and im also taking my last Alevel this year. When it comes to extracurriclars , i dont have much. I have done about 5 and Im not really sure if I even have a chance at any of these universities because of how little they are . I would have done more activities but to be able to complete all of these subjects in 3 years I had to give up school breaks so I didnt really have the time to do more. After watching a lot of videos on youtube I have become hesitant and im not sure if I should apply or not. It would be extremely helpful if someone gave me their insight on this. TIA
