GMAT Quantitative Section | Re: Quant 700-800 questions(PS+DS) with solutions

Thanks Bunuel , need your help, I did write GMAT last week scored 530 (Q 41 V 22) . I want to prepare for 3 months and try again.
This is my only escape and solace. Could you please help me which other prep/practice material I should use for PS/DS.

Thanks a ton for all the help !
