There will be some changes beginning with the SAT testing this weekend. The test has seen its first major change in the past 10 years. First off, the essay portion will be optional. It became required beginning in 2005. With this change, the best test score is back to 1600. Wrong answers will no longer be counted against students, so you can guess again. There will also be less questions and some math questions can now have a calculator used on them.
