My mom wants me to take the ACT as well as the SAT. I took an ACT practice test, and since I don't really know anything about it, I was wondering if someone who did could comment on my scores?

Scale scores:

English: 31 - 97th percentile

Math: 23 -70th percentile

Reading: 36 -99th percentile

Science: 27 -93rd percentile

My composite score is 29.25. -95th percentile

I'm worried about the math I missed 20 out of 60 questions. I take the ACT on the 15th. It said the average math score is like... 20.something so technically I'm above average, but I still missed 20 questions so wouldn't that mean I made like a 66% and failed? I'm pretty worried about that. Does the 70th percentile mean I scored better than 7 out of 10 other people? See. Told you I sucked at math.
