General GMAT Questions and Strategies | Need help!!! GMAT on Aug 24th,2017

I am giving my GMAT on Aug 24th,2017. I roughly have 40 days left for my exam.... Need help on how to improve my score and any changes/recommendations required in my Prep Process.

CAT 1 : 450 - Q38(23 of 37) V14(18 of 41)
CAT 2 : 590 - Q43(31 of 37) V29(28 of 41)
CAT 3 : 570 - Q40(30 of 37) V29(26 of 41)

In my prep process
