Good question, Jean.
I was confused before, but even more so after I looked up the definitions of aptitude and achievement.
Webster's defines aptitude as 'natural talent; ability to learn quickly and easily' and achievement as 'the act of attaining or carrying out successfully".
So, my thoughts are that the SAT was designed to provide a mechanism for upward mobility based on natural talent, not social class or heritage. That would be aptitude, right?
But, in my notes I wrote that the test was supposed to be a predictor of 1st semester grades in Ivy League schools. Which would be achievement, right? What do you think???
And, why might the answer to #7 matter - hummmm
I'm not sure.
