Gruber’s Complete SAT Guide 2009 is it any good?

Hi and welcome to my blog,
I opened this blog to help anyone who is preparing for his SAT.
I remember myself when I started - I was so lost and in such a panic.
Luckily I got this great SAT guide that helped me a lot . So study hard and good luck!
Alright well I took my SAT last month and did poorly on Reading/Writing. I did do good on math aleast but I need to retake it and with most college applications being due Jan 15 I am signed up to take it again for Dec so I can get my scores back in time to send them off to colleges.
Now I only have a month and I want to make sure I get the best book out there to help me cause im pretty much going to lock myself in my room haha and study this book all day and night learning new techniques and strategies.
Do you all recommended any other books out there? Or am I good with this one.
Gruber’s is actually best for math…not as good for your weak areas, I’m afraid, but it may be enough for you with such a tight schedule. If you don’t have it already, get the College Board blue book, and do as many practice problems as you can between now and December. For the writing multiple choice, this is a great reference: http://www.sparknotes.com/testprep/books/newsat/chapter8section3.rhtml For vocabulary, check out http://www.word-nerd.com – it’s a great way to boost your vocabulary efficiently and quickly. If you really want another book for strategy, the Princton Review is good. Good luck.
