MIT undergraduate admission for international students is fiercely competitive. They only admit about 5% of international applicants every year and they cap their international student admissions at less than 150 per year. To get in you need to have a stellar academic record and standardized test scores, but you can bet that most of your competition will have these. To be a stand out candidate you should be able to show dedication and achievement in your desired field of study: projects, awards, extracurricular activities...anything that can indicate you go above and beyond what's just required of you in your regular coursework can help.
