<p>I went to my local library and borrowed the “ACT for Dummies” book. I think there were 2-3 practice tests on it and I thought they were pretty good. I did the test on paper though (because it was library property). </p>
<p>For science specifically, I went to Barnes and Nobles and read the Princeton Review 09’ Edition (I did poorly on science my first time). The tests --atleast the science portion-- were really similar to the actual ACT.</p>
