Question about SAT in the admissions process

<p>I heard that colleges will look at every SAT score set sent to them and take only the highest score from each subject when molding a students final SAT score for admissions. Assuming this is true, what would happen were I to score a 640 on math and 510 on reading the first time, then got a 510 on math and a 640 on reading the second time? Would prestigious colleges be more likely to accept me for getting a 1280 overall or would they likely decline me due to the inconsistency in my score reports?</p>
