For schools that don't superscore, which ACT should I send?

I might be worrying a bit too much about this, but I’ve scored 30 three times. However, my subscores have shifted around.
30-31-29-28
29-31-33-28
30-28-27-33
Should I use the more consistent ACT or one that shows strength in an area? Not sure if relevant, I’m planning on being a Comp Sci major.

I would send the second one… scores are more consistent. The second is equal to 30.25 rounded to a 30.The first and third both equal to 29.5 which is rounded to a 30 composite.

What were the categories for those scores? I have no idea which is math, english, etc. Where was your highest math score?

The scores are in standard ACT test order.
English-Math-Reading-Science

The one I wouldn’t choose is the 3rd one. I am personally thinking that English and Math sections may be treated a little more importantly than the other two sections, just like there are some schools like Cal Poly which only look at English and Math sections. Yet, English, Reading, and Science are, in a way, all language problem test, but Math is totally different from the other three. You don’t want to show your weakness in Math section. I agree with ansiousteen. I would pick the 2nd one, if I were you. My score is similar to yours and I totally understand your concerns. Good luck to you!
