So my junior year in high school just ended, and I took my first ACT this June and I scored a 23 
I came across the ACT Online Prep for $40 ( http://www.act.org/content/act/en/products-and-services/the-act/test-preparation/act-online-prep.html )
Anyone tried it? Is it worth it?
no, the materials they used are from mcgraw hill.
