This test is taken by high school students prior to enrolling in college; it is offered on national dates at the main campus. It is a paper/pencil test. Nearly every college in America accepts the SAT or Subject Tests as a part of its admissions process. That's why more than two million students take the SAT every year. Students must register by the deadline or be subject to late fees. Standby test takers are also allowed on the day of the test. They MUST arrive at the test sight with a completed registration form in hand along with payment, ID and pencils.
