Reliable and challenging Questions with best approaches

I have solved most of the ''GMAT Club tests'' questions. Makers of these questions really deliver what they stated. Hardest quant questions I ever solved during my GMAT preparation. Explanations and ''less time consuming approaches'' are very helpful in learning. In these question almost every quant and verbal concepts are tested. Even if you get the wrong answer then there is so much to learn. Every question gives you something to understand. Both verbal and quant parts are composed of good quality question.
