Best Prep to raise a score by 3 points?

<p>So I took my act. I ended up with a 27. So... Here's my score..
E: 26 (I know I can raise this.. I had to fill in some at the end)
M: 24 (same as English.. I think I was too nervous.. haha)
R: 31
S: 25</p>

<p>What is the best book and method to use to raise my scores in Math, English and Science. I've heard Barron's from most people. Anyways, suggest what you did if you raised your score by more than one point!</p>

<p>I hate to say this, because it IS the most expensive, but I was in the same boat as you but then I called up Princeton Review and for the painful price of $125/hour, my score jumped from 27 to 31! </p>

<p>Its painful, but in the end, so worth it!</p>

<p>Best of luck!</p>
