<p>I imagine quite a few of the kids headed to the type selective schools have taken the SATs three times. I think the decision is yours. Our school actually ranks based on a formula that takes into consideration standardized test scores using the highest single sitting so i can understand your “pain” of having the GPA but not the national scores you want for your school to give you the “nod” to the top 10%. If you were my son/daughter and you really wanted to try it again, I would say to do so. But do understand that it is not a given that a student will improve each and everytime, as someone said, there is a point of diminishing return.</p>
