What ACT prep course is WORTH IT?

<p>I'm looking at some ACT prep courses, and they all practically say they same thing. What I want is some real feedback from people who've taken these courses!</p>

<p>So my real question is...
What course do you recommend?
How much of an increase did you get?
Also, is it worth it? I know many courses are rather costly. </p>

<p>Thank you! :)</p>
