I need section help

<p>So I really want to score 750+ on math and writing.
I am currently scoring about a 680-700 each test using Princeton Review Tests.
How can i bump it up? I am giving myself 8's on the essays.</p>

<p>I just bought Gruber's math for SAT yesterday. Should I buy Barron's Writing Workbook? I Gruber's good for math? Is there a different book I should buy?</p>

<p>I heard that Barron's SAT 2400 has a phenomenal writing section but I don't know where I can pick one up. Barnes and Noble's said that they discontinued the 3rd edition and that the 4th isn't out yet. I can't order one online cuz my exam is on saturday.</p>

<p>the shortest and the most effective way to raise your score is by answering questions that appeared on real tests.barrons, grubers and other books are not made by the actual SAT test maker. so, they really differ from the actual test. try the blue book and the online course. It is also good to answer previous real tests.</p>
