Can I still get to a top US college?

I´m from mexico, just finished my first year and I lost all the first stages of the IPHO (International Physics Olympiad) and IMO (International Math Olympiad) My school is not linked to any science fair institue neither they have any research opportunities, my teachers aren´t very good at teaching and in my first semester i got a grade of 9.5/10 and in the second a 9.2/10, while smarts kids at my school tend to get 9.8/10 or 9.9/10 (We do not use GPA systmem) and I do not have currently any extracurriculars and I´m not good at anything, of course I want to improve my next year but I feel really sad and disappointed, do I even still have chances?
