Review from someone in the mid of his prep

I had been relying on GMATclub workbook and other mock tests available in dumps but using GMAT club gave me a new perspective. It is extremely thorough and as close to possible to the real tests. You get a thorough explanation of every question and the best part is, the interface gives you everything you need to analyze your score and improve on the weak areas. You can sort by correct or incorrect and follow up in the review discussion on the forum. The only downside is limited subscription which I hope to extend soon.
For anyone relying on more expensive tests, give it a shot here and you will surely find the tests worth the $$$ and/or effort.
