Manhattan GMAT Math book

[MakeitHappen]

Hey all..am having a hard time finding anything concrete for my gmat math prep. i am not in touch with math at all. so far, i have looked at Kaplan GMAT Premier Program,OG 12th edition and a few basic math resources online to get in touch with math topics. after i go through each topic through resources mentioned above, i try to work on questions but am still not able to get the answers. I dont know where am I going wrong!! I am I not getting the concepts right?? I am getting really worried about how to prepare for the Math section!!!!!!! Pls help me out, this is my 2nd attempt at gmat and my confidence is at an all time low!!

What other resources could I possibly use?
From reviews seen online,Manhattan GMAT Math Strategy books are useful for people who are aiming for higher scores. My aim is to get a high score but at this stage without getting the basics right, I don't see any point in investing in them yet. HELP!!!!!!!

The Manhattan Math Strategy guides start with basic concepts and then later have advanced chapters, which are well explained. I am referring particularly to Guides 1 and 3. Some members of this forum feel that Guide 5 could have been better. I've worked with Guides 1 and 3 and would recommend them without any reservations.
