<p>I bought the real ACT guide and recently checked out Barron's ACT guide from the library. The Barron's guide is a million times harder than the Real ACT guide. (From the practice tests). I justed wanted to let you all know this. I guess I will prep from both but I think Barron's just has all the hardest questions you will see in one book and the Real ACT guide is pretty much the real thing.</p>
