Abolish the SAT exam?

There is an on-going debate about whether or not the SAT test should be abolished and replaced with the subject tests. I feel that the SAT test needs to stay around for several reasons: 1) the majority of America's college campuses accept it for a means of admissions criteria and 2) it possible that the test can show how a student performs on basic aspects of education: math, reading, and writing. Two of these are essential to do well in college. The subject exams only test to demonstrate on how a student performs in that particular subject. If the student performs poorly on the general SAT but performs well on the Subject tests, this can show that the student might be capable of performing well in college.
