GMAT Study plan help

Hi All,

I have 2 more months for my GMAT exam. I took an Initial Diagnostic test without even knowledge of GMAT topics and got around 400, i know its not a score at all .
Could any one help me out for Quants section on how to approach this section as i feel i am little weak than the Verbal section. if any one give me a heads up on Quants will be greatly helpful.

Thanks in advance
