I completed all of the

GMAT Club tests over a span of 2 weeks prior to my exam. The questions were fair and representative to a certain extent. I found that on the test there were more "applied" math problems. We are used to the speed, rate, work problems but I had two questions dealing with volume & density and another dealing with electrical power. Pretty straight forward stuff but it threw me for a loop and I ended up messing up all three questions (first three questions of the damn test!). Hence the 49.

Thinking about buying...

I would recommend this to everyone but only after you build up a very solid math foundation. It's one thing to understand how to do every type of math question but its a totally different thing to handle hard question after hard question in a timely manner. The GMAT will continue to give you time consuming and tricky questions if you continue to perform well. The

GMAT Club tests represent this aspect of the test well. So if you are scoring high on the practice tests or know your math very well, buy these tests. If not, keep working away on math problems until you are scoring high in practice (untimed).

The questions are very representative. After completing all of the tests I found some of the harder concepts like probability and inequalities to be much easier. I noticed the variation in question types and the tricks and pitfalls in both types of math questions. Data Sufficiency also turned into a strength and problem solving questions became "gimmies"
