| If you have just one week to study, and plan to spend less than $30. This book with ETS Official Guide is what I recommend you to get. Cliff Notes gives a brief review, give you one diagnostic test. If you have $100 budget and months to study for the test, this book would like be as helpful as other books. However, If you only have one week and just want to have a brief prep, this is a must have. |
