It depends what schools you are applying to, and how good your scores have to be for those schools. If this is the first time you took it, take it one more time and see what happens. You can take it again knowing your existing scores are very good, and you have nothing to lose by retaking.
I’m really debating this because tomorrow will be the last day to register for the December SAT, and subsequently the last chance for SAT Scores to be sent to RD Schools.
Not worth retaking in my opinion unless you are applying to a rigorous engineering program, which you it doesn’t seem like you are. A 740 is very respectable.
It’s an impossible call. Realistically, it is silly to entertain retaking a 2300 but if your math score is at or below the 25th % of admitted students, then I would have to give it a shot. You have to imagine that some of those who scored in the bottom quartile are hooked applicants (athletic recruits). Assuming you are an unhooked applicant, you would want your scores to be on par with your competition.
I don’t think a 740 is considered a ‘low’ math score unless you plan on going into physics or engineering. Also, if youre applying for a school that doesn’t participate in super scores, you probably shouldn’t risk getting lower than a 2300 unless you’re very confident in your reading/crit skills.
