Best Quant Book After OG11

What would be the best material when aiming for a "top score" in quant?

The best that I found:
https://www.gmatmathbible.com/

I've heard that this is a great resource, as well.

Also, you should consider the GMAT Club Challenges.

What about 1000 PS and DS, are these not good enough?

GMATHBIBLE..

how many questions and tests does this bible contain? How much time one needs to work on this after having OG completed.

How do u rate it when compared to 1000 RCs and CRs?

Gmat Math Bible is a good book, definitely, but don't expect anything, and I mean ANYTHING, that is 48+ material. Probably there is not much Q45 contetnt either... If you are a top scorer with rock solid fundamentals this is not a book you should spend $45 on.
I bought it because I have constantly listening "you should improve your fundamentals" and things like that. Lurking througout this forum I found that my fundamentals are realy weak, especialy in certain areas. I have some 50+ areas (for example geometry) but also had some 20- areas. Some of my quant skills are a little bit rusty and some I never even obtained, in that situation it was intuitive that my basics need urgent repair while some areas demanded greenfield construction. "Improve your basics", "boost your fundamentals", yeah man, but how? What book should I buy, what material should I use and, in the same time, avoid situation of overlearning, learning useless concepts?
Then I saw this book and decided to buy it because I saw some demo stuff from it. It is a good book, no argue about that. It covers 40 concepts that are tested on GMAT. Each chapter consists of short tutorial, drill and practice area. Drills are series of lightweight questions designed to upgrade your basic and are especialy usefull for people with weak fundamentals in particular area, practice questions seem like real GMAT stuff.
Don't expect anything too deep overhere, it's just a basics but thouroughly written, properly selected and well explained basics. It also gives some usefull tips and hints but brings nothing new compared to ManhattanGMAT. Actualy, that's the way I am using this book: as a suplement of five Manhattan quant books. First, read through Math Bible for some fundamental stuff, then jump to Manhattan book that covers that same area looking for some advanced portion of the same topic.

hi,
is that book an ebook or a hardcopy ?

It's an ebook. Couple of hours after payment they will send you PDF file on the designated e-mail address.

Someone once posted his/her advice that you should seriously solve and understand the concepts of the last 30 PS & DS questions in the OG11 book. Learn them by heart. I totally agree with this advice!

Additionally, what really helped me were the hard PS/DS questions of Kaplan GMAT 800 book. Once again understand the concepts!

And finally, practice, practice, practice, whatever you can get under time pressure.

cheers

PS in GMAT800 isn't really harder than in OG :/
Although, the DS part contains tougher questions but definitely not tough enough to get a perfect quant score.

Hi Guys,

I'm almost done with the GMAT MATH BIBLE, it's a great resource.

And i was willing to sell it for $25. If anyone is interested please pm me.

Thanks & regards,
