ACT Test Information Release (TIR)
Request a Copy of Your ACT Test Questions and Answers
If you take the ACT in April, June, or September, you can request a copy of your questions and answers for up to 6 months, to use as prep for your next ACT test.
Should you order the TIR? In my opinion, it is helpful if you are planning to take the ACT again, and you are scoring under a 30.
Otherwise, the only real benefit (in my opinion) is to see what you missed. If you are curious about that, then go ahead and order it.
