GMAT Strategy

Hi all. I've just finished a manhattan diagnostic test. My score is as follows.

SCORE & OVERVIEW OF RESULTS
TYPE SCORE ESTIMATED PERCENTILE RANK
Quantitative 43 70 %
Verbal 32 67 %
Total 620 76 %

I will take my real gmat exam on 3 rd of August. I have more or less two months .

I need comments about my weaknesses and how can I improve all the weaknesses I have . (Note : My reports of Manhattan Gmat CAT is attached to this post , you can analyze my weaknesses)

I am working now in a company, yet I study for 5 hours a day after I return home and 12-15 hours for the weekends. I've taken vacation for 2-3 weeks before the exam so I plan to work whole day.

I am studying section by section. I've started from SC and continue with RC and CR. I have Manhattan books . However I think I need additional books for SC and CR. Please give your suggestions about SC and CR books and materials.

Gmat is my dream and I will do my all to beat it.

I wait for all of yours comment.
