From Quora: My Answer to: "Is giving [sic] sat important for someone with social sciences background considering I don't plan on applying to the US or UK, however I do plan on applying to universities in Europe, do all countries require sat?"

Probably not. I can’t give you a 100% certain answer, but I don’t believe schools outside the US require the SAT. Some schools may accept it (e.g., schools in Canada, certain colleges in the UK or Australia), but if you’re planning to attend school in mainland Europe, you probably don’t have to take the SAT or submit the scores if you do take the SAT. Your best bet is to look at the websites, and contact the admissions departments, of the colleges you wish to attend. Good luck!
