Q42,V22. 530. A plea for help and guidance.

Hello everyone. I gave my GMAT yesterday and scored a Q42 and V22. Below I am going to write up the prep materials I used, Please critique my study schedule and flaw in my preparation and tell me what I need to correct. I am taking a month off from work and reappear again. Will it be enough time?(Given my current score) Please let me know.

Books I Used:
Nova Math bible.
CR Bible.
Manhattan SC.(I did not do the idioms.)
Test prep sites: Veritas prep

I gave the mocks for the last one week. I gave one mock each day and scored around 600+ (600-630)

The books below are the books I possess:

OG 12 th edition.
OG 13 th edition.
OG 2016 edition.
GMAT Quantitative Review.
GMAT Verbal Review.
RC99
Aristotle SC.
Princeton Review-Premium edition

Can you suggest what I need to improve? Based on my scores can you tell me where I stand? Are my basics weak? Should I start from the scratch? What do my scores imply? Looking at the books I've completed, do you think I practiced enough at all? Do I need to rely on manhattan prep tests? I enrolled for manhattan mocks.. Looking back, I scored 580 in their mocks.

Please go ahead and let me know, be as brutal as you want. I have a month of time on my hands.

So, let me know. Thank you very much.

I want to know where I went wrong so I can change it and make a difference in my score. Thank you for your time.
