The 60-Day GMAT Study Guide

hi all,

First and foremost, without knowing what have i got into, i have booked my GMAT exam on Dec 2nd 2013.

im from malaysia, graduated in film and animation in 2005 and you can say math was long gone in my life except when im getting my salary and paying my bills. currently working in a TV station as a promo producer.

after reading a lot of success story, i believed i need a good study plan and after calculating days that i will be studying minus holiday, it will be 58 days from today. i also will be taking IELTS on 26th Oct since English is not my first language.

i have not bought any reference books yet only from MBA.com( gmat focus, question pack & test pack).

From i have read, Princeton Review are good for people need refreshing in math. maybe i need to buy OG and also Kaplan GMAT. since i want to follow the 60-Day GMAT study guide, i guess either i buy Manhattan GMAT's Complete Strategy Guide Set (5th Edition) or subscribe to GMAT Prep Now's Complete Online Video Course (Modules #1 to #16) but depends on the budget agreed by my wife im hoping to get all the books by this week.

i have tried the GmatPrep practice exam 1 and got 240 which i believed the lowest of the low aloong way to go to 750!
reviewed the mistake i done but the practice exam don't have explanation so i have to track back from the answer.

any feedback for this newbie on the study plan and recommended books would be awesome.

thanks.
