Perfect way to increase your score

I've been using the GMATclub tests and can say that they have had a large impact on my ability to successfully tackle the harder, more obscure question types such as combinations and high-level geometry. I think these are a great supplement towards the end of anyone's prep for the GMAT to really shore up their weak points in quant and achieve their desired score. I recommend not to look at the projected score the tests provide, but to make sure you really focus on the solutions and fundamentals of any questions that you miss while taking the test. The projected quant scores can vary wildly and most likely don't accurately represent what you will get on the actual test day.
