1270 is definitely an above average SAT score. However for certain computer science programs at certain colleges, it will not reach the bar for acceptance directly into CS.
But really, it’s a decent SAT score. IIRC, that’s about what my kid had when applying to colleges. She got accepted everywhere she applied except her one reach (she only applied to 5 schools total and one was a parent request). Even with her “modest” SAT score, and no calculus in HS, she managed to graduate with a degree in engineering.
There ARE colleges where this kid’s stats will get him into a CS degree seeking program. The list above is a good start.
