Best test available

The GMAT club tests are great, they are better than the practice tests from a few different sources. Each question comes with detailed explanation on the answer and with statistics on how everyone did. This helps to give you, the test taker, a good perspective on how you are doing compared to others. In addition, the quiz component is excellent! It allows you to drill into different topics and sections that you want more practice. Overall, the entire format, the look and feel, is like that of the real test. This helps to allow you to be familiar with the actual test. Overall, I highly recommend using the GMAT club tests. Only thing - I hope that GMAT club will put in more verbal questions!
