ACT Math Help

<p>I'm taking the ACT this Saturday, and I'm definitely not ready for it.
I have taken two practice tests from the Real ACT prep book, and English, Reading, and
Science were a breeze for me. But I'm having a lot of trouble with the math section.
I only got 39/60 right, which is awful. I did better on timing the second time through,
but my score was still low. I'm not sure where to start studying, but I know that the graphing questions threw me off completely. Also, do I need a graphing calculator? I don't own one</p>
