Hello,
I am taking my GMAT on March 20th, 2010. I need suggestions on study plans. I took the GMAT once in 2008 and received a dissipointing score of 470 but I was not well prepared for it. I did not study the foundations in depth. I want to try again and reach 690. I just took one of the exams from GMAT prep and received score of 420

.
I need suggestion on good study habits and strategies. I have a full time job and a lot of my time is spent traveling. However, this is not an excuse. I am determined to get 690.
So far these are the sources I have used to study:
Kaplan GMAT Math Foundations (a suggestion I read on this website)
Kaplan Premier Book with program cd
Kaplan class - I took this class in 2008 when I first took my GMAT. I am not too sure if it helped me.
Offical Guides
If anyone can provide some suggestions, that would be great.
Thank you!!
