GMAT Club Quant tests

I enrolled in eGmat verbal online course and got free access to gmat club tests with it. I have solved questions from multiple forums and other sources like Veritas and Manhattan. I agree that Manhattan helps in building a strong foundation for basic quant, but the questions in the guides are relatively easier. I took couple of Quant tests and to be honest many a times I was disappointed in my performance. However, the level of questions are good. In addition, each question thread has multiple ways of solving one particular question. This helped me a lot in couple of questions whose solution I was not very comfortable in understanding. If someone solves all the quant tests, I think he/she is good to score high in quant on actual GMAT.
