However, whether it's "average" or "bad" depends entirely on your aspirations. If you're aiming for highly selective universities, it might be viewed as on the lower end of competitive scores. For less selective colleges, it's a strong score.
The unevenness between your Math and Reading/Writing scores might also be a factor. Colleges will look at the overall score, but some might weigh the individual sections differently depending on the program you're applying to. For instance, a strong math score might be more important for engineering programs.
In short: Good score overall, but context matters. Consider your target schools and their average SAT scores to better gauge how competitive your score is.
