as most of you know, the december act scores were delayed--by many many many days.
so, in order to meet my jan 1st deadlines, i submitted my october act score of 28.

however, the december act scores were released yesterday--and i got a 30 (:
so, i submitted my dec act scores as well.

now all of my colleges have both my oct and dec act scores, and i was wondering whether colleges take the higher score or do they average both scores/look at both scores?

thanks!
