Are SAT IIs required? If so, what is the accepted score range?
SAT IIs are not required. You may submit SAT II scores, if you believe they provide additional support for your application, but it is not a requirement for admission. Sometimes SAT II scores provide a more complete picture, particularly if some aspect of your application does not reflect your best performance (for example, if on the SAT IIs you have a higher score or percentile than on the SATs).
