Need Deperate Help,Step towrds final battle in SEP 1st week.

Hi All,
I have decided , that i am going to appear final battle on first week of Sep.
Now these 3 mnths are really crucial for me.As a working person i need to manage my time line.
So i need suggestions how should i plan myself.
This will be my 2nd attempt.In 1st attempt i scored 470 .
The materials i have :
OG12
OG 13
MGMAT sample test series
PDF Materials for SC CR n RC and for Quant, available from GMATCLUB forum shared by honorary members.
Most of the question availbale in these pdfs are matching with MGMAT exam questions.
Currently I am scoring in 630-650 range.
Help and suggestions will be much appreciated.

And thank you for all the replies i got for my previous post 'stuck at 590, need desperate help'.
