My D took the SAT in 7th & 8th grade, and was in the "C" range both times. She was not SET (but only because she took the test 1 month after the age cutoff; we didn't even know about SET until after that... too bad). We registered her scores with CTY (in case she ever wanted to attend a camp), and they invited her to participate in an online chat forum called Cogito. That was a great benefit! As a middle schooler, she was having a hard time finding "her people" (PG kids) -- this online group was a great resource at a tough time for her.
She never did CTY, either. But she did go to Davidson THINK for two summers (age 15 & 16), and LOVED it. She used those SAT scores to qualify.
So I consider it well worthwhile.
