I have to take my ACT tomoroow, wish me luck! Any pointers?
Good luck, good sir. I took mine last year. I will warn you (you probably know this) that the actual test is much harder than the practice stuff! Any pointers I can give can also be found in the ACT books. You'll do fine.
As has been said already, leave your stress at home!
Do not worry if you do not know the answer to a question right away, read the question and usually the answer will present itself even if you are unsure about how to do the question.
Remember that there is no "pattern" to the answers. Even if you are guessing, three "Bs" in a row is not a reason to change a guess.
Trust yourself, you know a lot more than you think you do.
Good luck, and happy testing!
Good luck, I'm taking mine soon too : )
