hey guys,

hope all is well. currently i have the OG 11, the purple and the green and the 2007 set of 8 manhattan books for my prep for the gmat exam.

i was wondering whether it is necessary to buy the OG 12th ed and the new version of the 8 manhattan books? has anyone encountered any additional benefits to having these books (be it psychological)?

I wrote my gmat exam and scored a 500. i finished all of the OG 11. which is why I am thinking of getting the OG 12. I want to enhance my score to around a 600.

so far, my verbal is considerably better than my maths (V31:Q27) so ofcourse if you have any recommendations with regards to good maths review books please do let me know so I can purchase them.

I am thinking to study my *** off first and then when i feel that i am ready apply to take the exam as opposed to booking for the exam from now and then running out of time.

i would really appreciate your expert advise. also advice pertaining to how to best prepare for my rewrite would be highly appreciated.
