There are lots of things you're required to bring and lots of optional items. Check out the College Board's list of acceptable things to bring at: http://collegeboard.com/student/testing/sat/testday/bring.html

depends what you mean like that as like a worksheet that will help you but dont pull it out during the SAT.

Yeah, just go to the college board website. The things you really have to bring are your admission ticket, and photo ID.
