I am truly torn. After working through the math section of PR's Cracking the GMAT it is apparent that I need additional study. I'm deciding between some of the specific Manhattan books, the Kaplan math workbook, and now the new entrant, the Kaplan math foundations book.

I should note that I am less concerned with additional sample problems accompanied by many of the books, but most concerned with what gives the most thorough, succinct, correct instruction on math concepts. I'll be purchasing the official guide to make sure I have a gauntlet of questions to test out my knowledge on, once I've studied up.

Are the mistakes in the Kaplan Foundations book only present in the review questions, or are their some errors in the fundamentals they teach?

Are Manhattan's books worth the added expense? i.e. If I purchase 3 math review books from Manhattan I am looking at roughly $50+ vs $15 for either the Kaplan Math Foundations or Kaplan Math workbook? Is this a 'get-what-you-pay-for" situation?

I ask because I cannot find any of the Manhattan books at any local retailers, so I can't actually take a look at these books before purchasing.

The Official Guide for GMAT Quantitative Review, 2nd Edition

The Official Guide for GMAT Quantitative Review, 2nd Edition is out!

There are 44 new Problem Solving and 31 new Data Sufficiency Questions (a total of 75 new questions out of 300).

List of Changes:
Problem Solving (PS)
- 4 new easy questions
- 21 new medium questions
- 19 new hard questions
Data Sufficiency
- 13 new easy questions
- 8 new medium questions
- 9 new hard questions

The main issue with the first edition was low question difficulty. This edition addresses the issue slightly, but as you can see, not by much. One issue that was fixed is the total number of questions. The first edition claimed (just like this one) to have 300 questions, but only had 294 - how can you make that mistake in the Official Guide for Quantitative Review? The question split is 176 for PS and 124 for DS.

As to content, changes, it is interesting to see many of the tables and data-interpretation questions go and addition of sequence questions. Also, DS lost many of its arithmetic questions, which were replaced by Word Problems.

Overall - pretty much the same book - would have loved to see more new questions, but $12 for 28 new hard and 29 medium REAL questions is not bad. By the way, the first edition is on sale right now The Official Guide for GMAT Quantitative Review for $6.78!

Here is the full list of new questions for reference:
PS: 1, 2, 7, 41, 56, 60, 61, 62, 64, 67, 68, 69, 70, 71, 72, 78, 79, 80, 81, 83, 102, 103, 108, 112, 117, 131, 135, 142, 145, 146, 147, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 160, 162, 173

DS:
1, 6, 7, 9, 11, 13, 14, 16, 21, 22, 24, 31, 33, 43, 48, 51, 66, 70, 73, 79, 82, 85, 96, 102, 104, 106, 107, 111, 116, 117, 122

Good Luck on your GMAT!

Since GMAT is an adaptive test and adapts to YOUR level of difficulty, this is not the right question to ask. If you are wondering which book has more of harder questions or ones that resemble the real GMAT, then that's the GMAT Official Guide 12th edition.

The Quant OG lacks harder questions.

new to the forum...

Is it me, or is Princeton Review 1012 absolutely riddled with errors? So far I have found at least 8 mistakes in the answer keys or diagrams.

thanks,


acc

I have not solved through the questions, but that's what the feedback comes back.
The unfortunate reality of a new book - was released not fully proofed, definitely makes studying more complicated.

By the way, if you can, would REALLY help everyone if you can post question numbers and a list of issues - would help a lot!

Here are the books that I have from the Manhattan GMAT so far and my thoughts:

1) Word Translation- Loved it. The most difficult material from the math books that I had from them. That's probably because this material is in fact the most difficult in the quant section. Even the easiest Word Translations are more difficult than some medium difficulty numbers property questions. I feel like this taught me some strategies that Kaplan never taught me. Such as the RTD/RTW table. The anagram method (though I don't use it much, for some reason I find the regular formula more intuitive).

2) Numbers properties- Pretty good. However a great majority of it was stuff that I can easily solve. However things like number of factors might help on test day. Also helps with many data sufficiency problems.

3) Geometry- Good book. Some of the stuff it goes over, is stuff that I got wrong before on CATs and wouldn't have if I knew it. Like the largest possible area of a triangle when you know 2 sides. Also, similar triangles. Diagonal of a rectangular solid. It seems like it didn't go over the hardest problems (polygon's within polygons etc.)

The McGraw-Hill gets a really really bad review in amazon by the Gmatclub, but it is because the text has tons of errors that could mislead you on your study.

The practice tests dont have hard questions, they are just average, o a little above it. The answers to those questions are not deep, they just state it with one simple sentence or two. So i didn't find that much of a learning opportunity by doing them.

However, the book has chapters dedicated to the admitions process, and life during and after Bschool. I think the value of the book is on how the authors put the admitions process, your career and the gmat into perspective.

It is a good read, but not because of the excercises and math theory. So if you don´t have much time to study, stay away from that book.

After practicing OG-12, I feel I should understand formulas of arithmetic and geometry in detail. I am fairly good with work problems but require thorough understanding and practice on arithmetic and geometry problems.I am not looking for a very basic math book but slightly above average.

Could you please suggest a book which has above average math formulas and strategies, I am ok if the book doesnt have practice questions.

I am confused among the below listed:

1. Kaplan Math Foundations
2. Kaplan GMAT Math Workbook
3. MGMAT Guides

:) Very simple:

1. Kaplan Math Foundations - most basic book with some basic examples - good to build confidence but does not really challenge you (good if math is weak or you forgot many things and want to be diligent in review)
2. Kaplan GMAT Math Workbook - good middle of the road book (good time/return ration)
3. MGMAT Guides - extensive review (most results but also most time)

A good combination is Kaplan Math Workbook and MGMAT Number Properties - I will put that up in the first post.

Do the current Manhattan books (4th ed) still refer to the 11th ed of OG as the OP states? I have the 12th ed OG (and quant OG) and am looking for the best guide to help me increase my quant score. Don't have a problem spending a hundred or so on the Manhattan books if they are the best ones to get, but if they refer to the 11th ed of OG, that seems like a negative, no?

My fourth edition states on the front cover that the book is "updated for the 12th edition of the Official Guide!" You can click on the book's image on Amazon for a close-up view:

https://www.amazon.com/Number-Properties ... 0982423845

I am currently using the Manhattan math series, and I like these books. Each chapter has about 15 practice questions (sometimes more, sometimes less). These end-of chapter questions, which are not OG problems, test and reinforce what has just been covered.

I say go for it!

During a conversation with a friend, it hit me that I really haven't been exposed to GMAT math content since high school. I was an urban studies major and was able to satisfy a math requirement with a game theory course..lol. A while back, another friend (SAT tutor) recommended Peterson's GMAT/GRE Math Review. I also took note of GMATClub's review of Kaplan's Math Workbook. Initially, I looked at both but opted to really digg into the Peterson's book. I haven't really touched the Kaplan book maybe because of it's organization? Peterson's seemed to break down the content really well and in my case, served as a good primer to some Manhattan GMAT materials I'll be using the rest of the way.

Thanks for the feedback (I will try to review the book) - would be interested to hear your feedback about Peterson's after you are done with MGMAT guides.

I have just went through the Kaplan Math Foundations and the MGMAT NP book. The Kaplan book is very basic, I am very rusty in math but I found that it was difficult for me to relate the material in this book to actual GMAT questions. The MGMAT NP book on the otherhand is very relevant and is specifically targeted to the GMAT questions, I really saw a connection between the material and the actual questions in the og. I am excited to start the rest of the series. I'll keep you posted.

Yes, probably the fact that quite a few questions in the Kaplan Math Foundations are not GMAT-format questions does not help either. So, not recommended?

No I would not recommend the Kaplan Book, right now I am trying to make my way through all of the Manhattan GMAT Quant Books. I actually was going to buy the Kaplan Verbal Foundations but after going through the Quant I think I am just going to stick with the Manhattan GMAT set.
