Should I retake the SAT?

I took the SAT when I was in 8th grade and got a score of 1500+. Would colleges look at this score the same way as if I took it in junior or senior year? I am not sure if I should spend my time studying again if my score comes out to be similar.

First, you would have taken the old SAT and I don’t know that schools are still accepting that. Second, I don’t know that they’d accept one from 8th grade. I’d retake.

Did you ask the CB to save your scores? If not, their default is to delete scores from prior to HS.
