If I want to study abroad in high school, would it be good to push my senior year back and graduate 1 yr late?

You should be able to study abroad and graduate on time if you plan early enough. Meet with your guidance counselor to map out your graduation requirements and figure out how studying abroad will fit into your graduation requirements and timing. Studying abroad before you apply for colleges will allow you to draw upon your experiences in your application essays and interviews, and will help define and inform your college and major selection. In an applicant pool already inundated with impressive SAT scores, perfect grades, an abundance of AP classes, and stellar extracurricular activities, students with advanced foreign language skills and international cross-cultural experience definitely stand out in the college admissions process. Participation on a foreign exchange program signals to colleges and universities that you have already taken positive risks and stepped outside your comfort zone in order to push yourself academically and personally, and are likely to continue to do so throughout your undergraduate career; as this is something that admissions committees look for when evaluating your application, colleges and universities therefore look at students who have studied abroad very favorably. Furthermore, studying abroad would enable you to personally witness and experience other cultures, languages, and mindsets, giving you a toolkit with which to define and inform your professional and personal goals. This means that studying abroad will not only help you get into the college of your choice, it will also make you better informed when selecting your major and career path. I would encourage you to contact the universities that you are interested in and ask them how they feel about students who study abroad in high school. Over all, I think you will find it to be a major asset to your application. AYUSA Study Abroad is one company that offers a number of high-quality high school exchange programs in Europe, Asia, and Latin America. They have some advice on discussing studying abroad with your school and family on their website (see link below), and their program advisors can also give you more advice if you call 1-800-579-1709x5610.

Absolutely study abroad, but consider doing it for a year after you graduate, rather than before. In the UK this is quite normal, for people to take a "gap year" prior to uni. After seeing the world, the last thing you are going to want is to dive back into the h.s. scene. I guarantee you'll be totally over it, and that last year of high school would be just... no fun. You can certainly do a year-long volunteer or study program between h.s. and college - or even do several for a few mos. at a stretch each, in which case you'd experience even more cultures - and that will look very good on your applications.

my advice dont do it their going to take it the wrong wayy trust me just finish up your school year normally.
