Should I delete my ACT score?

            I got a 32 ACT June of my sophomore year (34 English, 34 Reading, 29 Math, 32 Science, 10 Writing). I just got a 31 on my February ACT junior year, (35 English, 34 reading, 29 Math, 24 Science). This superscores to a 33, but I plan on applying to elite/ivy league schools, who don't superscore as often as the SAT. Should I just delete my ACT score? I'm not sure if I'm going to retake it because I am retaking the SAT (which is my better test: 1490), but if I retake it I can definitely replicate the English and Reading scores as this is my strength. 

Thanks everyone.

A 31 won’t hurt you. They will use the highest score you have.

Do not delete because: (a) a number of colleges do superscore ACTs and you may want to apply to one of those; (b) even if the college does not superscore, it will not use the lower scores against you.
