Download sách Official Guide for GMAT Quantitative Review 2019
1. 300 real GMAT questions from past tests (mostly easy)
2. Great for additional math practice questions, but don’t expect to find any strategies or lessons here.
3. The practice questions are organized by level of difficulty
4. The practice questions follow actual GMAT test patterns – great to have one’s ear trained.
1. The book does not contain any strategies
2. It does have a few short review sections but they are very weak
3. Mostly easy and medium difficulty questions. Not very helpful to a person aiming to get above 700.
