Great learning source

I consider that GMAT Club Tests are very useful when preparing for the GMAT for different reasons.
First, because of their format (especially their style), which is very close to the one we see on exam day.
Second, I consider that the tools that are available to us when reviewing our performance are very valuable. The tests provide great resources to analyze each question, such as statistics, time references, and opinions from other club members (where sometimes we can find different approaches to solve a question).
Third, and one of the things that I liked the most about these tests, you can have direct interaction with the people that created/answered the exams. If you review your tests and you have doubts about any approach or question, you can post those doubts and receive answers to your questions in a short period of time.
