Is this a good score on the sat test 680?

The average composite score on an SAT test is between 1050 and 1060. So assuming that 680 is your composite SAT score, it is below average. Furthermore, looking at breakdown of percentiles, you would be in the bottom 1 percentile.

That said, SAT scores only really matter when it comes to what your plans are for collage, career, ect. If it turns out you need a different score, there are ways to take it again.
