In order to add one's SAT scores, a student adds his final math, critical reading and writing scores together. The total possible score for the SAT is 2400, but only a handful of students achieve the perfect score annually. The lowest possible score is 600.
Each of the three portions of the test receives a score between 200 and 800. The total score is the sum of these three individual test scores. A test taker's score report also comes with percentiles, telling the student where his scores fall in relation to others who took the test. Plans are in motion to change the SAT in a number of ways beginning in 2016. One of these changes includes making the essay portion of the exam optional.
