SAT
SAT is the acronym for Scholastic Aptitude Test, which is conducted by College Board (an association of schools and colleges in U.S.A). ETS (Educational Testing Service) administers the test for College Board for the students seeking admission to the undergraduate courses in U.S.A. About two million students in a year take the SAT to apply to various colleges, which helps in forecasting a student's freshman grades in college. This helps the colleges in making appropriate decisions about any student's ability to succeed academically. The SAT test score is also used as the basis for awarding meritbased financial aid.
About the test:
SAT has two versions: SATI and SATII.
SATI, which is a Paperbased test (PBT), is of threehour duration and it tests the verbal and mathematical reasoning skills of the students. It is scored on a scale of 200800 and is mostly taken by high school juniors and seniors. As per College Board, "A candidate can take the test up to seven times a year to improve upon his/her previous scores."
SATII is a subject test, which is of one hour duration and consists of mostly multiple choice questions. This is basically designed to test the subject knowledge that the student possesses and also tests how good they are at applying it. There are five general subject areas: English, Math, History, Science, Languages (which also includes ELPT). A college may require one or more of the subject tests for admission and placement.

Note: As per College Board "An actual SATI takes 3 hours because there is a fifth 30minute section, known as "experimental" section, which can be math or verbal, identical to one of the other four 30minute sections. This section, which permits the testmakers to try out new questions, does not count in the overall score, but because there is no way to know which of the five 30minute sections is experimental, the candidate must do his/her best on every section. Also, the section can appear in any order, except that the two 15minute sections always appear towards the end. Test takers sitting next to each other in the same testing sessions may have test books with entirely different sections.
The SAT Scoring System:
I. Total Score: Each of verbal and math sections are measured over a score of 200 to 800 total marks are 1600, out of which minimum 1100 should be obtained to ensure admission in to top universities.
II. Negative Marking: For the multiplechoice questions, if a question containing 5 choices is marked incorrectly, then onefourth of a mark is deducted. If a question containing 4 choices is marked incorrectly, then onethird of a mark is deducted.
III. There is no negative marking for Gridins.
IV. No points are added or subtracted for unanswered questions.
V. Any score in fraction is rounded off to the nearest whole number.
