To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
While this book is missing some math needed for the GMAT, it is perfect to get you back in the swing of things if you are rusty or been away from it for a while. The website access is great and I enjoyed learning from this book. You will need to do more math after this book, but it's a great start, especially when the GMAT is based on strategy, knowing rules and how to identify them fast. You can only get this from truly understanding the basics. I am glad I spent the time on this book than pulling my hair out and wasting time in more advanced books too soon.
It's a good book. It certainly helps with all of the things we learnt at school but need to brush up on! 4 star because I prefer the Kaplan Range, I think they're slightly better, but this book seemed to be the best option to recap on the foundations of maths.
As name suggests, this book covers only basic mathematics, but still topics like statistics, permutations and combinations, probability etc are not available. Please don't rely on it solely, do practice some good GMAT level questions.
I really liked the structure of the concept building in this book. For someone, who needs to start their quant preparation right from ground zero, this is a must. I must say, this book has helped me brush my basics.
Foundations of GMAT Math is the second edition of the book dedicated to a review of basic math principles. If you picked a GMAT Math book and having a hard time with it, this book is for you. Prepare to see pie charts explaining factions, multiplications table, explanations of what a multiple or prime is and how to factor numbers. If you have not faced math (or were afraid to) in the past 5 years, this book is for you. Here are some important facts:
PROS: - Very thorough - Fixed all(?) of the previous typos - Significantly reworked and improved the sequence of topics (now arithmetic is before word problems) - Added Arithmetic (2nd edition only) - Great coverage of coordinate geometry - Helpful and valuable divisibility and exponents section - TONS of bonus questions online (500+ of GMAT-format questions) - Have not verified every question, but hoping for quality better than the first edition (had many mistakes)
CONS: - The book has 500 practice questions but they are not in a GMAT format, rather a math-textbook format - Massive! Massive (see my images I uploaded comparing it to the previous edition) 500 full-size pages - I think the expectation is that you skip parts that you know - Some shortcuts (such as diamond method of solving quadratic equations) are confusing to those educated in formal math (but then those probably won't be using this book) - Easy (i know it is supposed to be), but still - only easy questions
Bottom line: if you are comfortable with other MGMAT books, this book is probably not for you. If you are uneasy about math, give this book a try - you don't regret it. It is fantastic value for the 800 questions it offers. Would also recommend you pick up Number Properties and Word Translations by Manhattan GMAT. If you have purchased a full Manhattan GMAT set of books and hesitating between this book and Kaplan's version, definitely get this one - it integrates better.
For reference, here are the topics covered by the book: 1. Arithmetic (new) 2. Divisibility (very helpful!) 3. Exponents and roots - helpful as well 4. Fractions 5. Fractions, decimals, and percents 6. Equations 7. Quadratic Equations 8. Beyond equations 9. Word Problems 10. Geometry (very extensive section)
