When writing on the SAT/ACT should I write in American English or British English?

I am taking the ACT/SAT in America, but most of the English I learned is British English, in where some words are spelled differently then that of American English.

Can anyone provide me past experiences or proof from the college board website? (I'd rather not have my information coming from a forum or Q&A site like yahoo answers.)

Thank you. :-)

From some people that have taken it with that very issue, the suggestion is to study American English: http://www.usnews.com/education/best-colleges/articles/2012/10/23/sat-act-test-prep-tips-for-international-students
