If this is the same person I think i answered you last question. For all the info check out
actstudent.org. Also just some general information:
ACT can be taken any year of college but most take them at the middle or end of thier junor years. You can take the ACT as many times as you want. Most southern colleges like the ACT while Northern or IVY league schools weight the SAT more. The highest you can do is a 36 and 18 is the national average. Thier are also two different types; the ACT with writing and just the ACT. Hope this helps
