<p>I'm taking the ACT on June 8th and I'm really worried about the math. I've been working through Barron's 36, one chapter left with that, and then I'll do the maths section in the Real ACT. I heard that Barron's 36 isn't very thorough though, so would it be worth it to get the Barron's maths and science workbook to really get stuck into over the next 2 weeks?</p>
<p>I have heard that Grubers has a really comprehensive math review. I have not personally used it yet, but I intend to purchase it this summer. </p>
<p>I have worked through the ACT 36 book by Barron’s. They really address the most difficult math concepts tested.</p>
