GMAT Club tests are very useful!

I have been using GMAT club tests for quite some time now. I find them extremely useful esp. for the fact that I can practice Quant questions topic wise - something I could not find easily on any other practice forums. Secondly, the look & feel of the test window is very similar to actual GMAT test, which is again very useful in training the mind to actual test scenario. Lastly, the analytics reports that come out are very simple to interpret and give a very good analysis of weak areas, timing etc. Also, the explanations of most of the questions I have gone through are very simple to understand and accurate.

Alsthough I haven't given my GMAT yet, I would strongly recommend GMAT Club Tests for practicing topic wise questions, timing and pacing for people starting to prepare for GMAT to build their confidence.
