How is one graded in the SAT exams and howmuch do u need to get into harvard university?

The SAT has three sections, each of which is scored from 200 to 800, inclusive, by 10s. Thus, you could receive a math score of 200, a writing score of 580, and a critical reading score of 800. In addition, you receive an essay grade, which is part of your writing score but also reported separately. The essay is graded by two separate graders, each of whom gives it a score from 0 to 6, inclusive. (A score of 0 means you are off topic, so for all practical considerations, your score will be between 2 and 12, inclusive.)





The score is calculated from your raw score. For reading, your raw score is the number of questions correct minus 1/4 of the number of questions wrong. Omitted questions do not count either way. For example, if you answered 60 questions and missed 10, your raw score would be 50 - 10/4 or 47.5. That number is then rounded to the nearest integer. (A score than ends with .5 is rounded up.) Finally, that number is translated into a score on the 200-800 scale using a formula that varies slightly from test to test.





For the math section, there is only one exception to this scoring formula. Some of the questions are not multiple choice, and for those, wrong answers do not count against you.





For the writing section, your essay grade is used to calculate the score, too.





Now, regarding Harvard, there is no minimum score. Like pretty much all universities, Harvard takes into account a variety of factors. SAT score is merely one of them, and you will find that people with perfect scores are sometimes rejected while people with significantly lower scores get in.
