I am not exactly sure what you are asking but I will try to give you some information on basic ACT stuff.
You can create an account at the official act websites for students at actstudent.org. this website lets you buy study materials and register for the ACT.
Hope this helps-
If you want to know about how to answer questions about the test itself, then know that guessing is okay. There in no penalty if you get it wrong. You just won't get any point added or deducted.
