GMAT Strategy

Hi,

I am planning to take GMAT in 2.5 months. Need help in terms of preparation for GMAT. I am planning to cover the following:
1. OG 11
2. Kaplan 2007 book
3. Manhattan Sentence correction guide
4. Kaplan 800
5. 1000 SC questions

For test:
Kaplan CD
GMAT prep

I had given one attempt in last august got only 640 because of lack of preparation, this time i want prepare thorughly.

Kindly suggest
1what all material needs to be covered
2.how to go about preparations in terms of whether to start with OG or something else.
3.Practice questions for maths & SC specifically

To what Eric said, I would add that you may look at the "I Just Beat The GMAT" section of the site to get some great ideas from people who have succeeded. In my own debrief I write about those study strategies that worked vs those that didn't work in my gmat prep. You can see it at (www.tinyurl.com/gmatpost).

thanks for the revert. I have read the " I just beat GMAT" forum, its quite useful. But i just wanted help in terms of is the list of books & test is sufficient for the preparation?

Kindly advise on the same.
