<p>I used 2 practice test from PR, and 2 from the Real ACT (saving the last for the week before the test). I think I may need more practice with the reading and science because I am struggling with them. I also wouldn't mind having more practice with math and English.</p>
<p>You can get 4 ACT practice tests for free by the ACT itself. </p>
<ol>
<li>The ACT has a practice booklet in PDF form on their site under test prep (Preparing for the ACT- ~80 pages)</li>
<li>Also on the website underneath that link are practice questions that equate to the same number of questions that you would see on the actual test.</li>
<li>Search on CC for additional ACT tests. Someone posted a link a while back to something called the Internet Wayback Archive (or something with a name like that). This will give you the link to two more old ACT prep booklets, the 2004 and 2007 editions, I believe.</li>
