Best way to get equip with top notch and fail proof quant skills

Initially,I started off with manhattan and veritas mocks.I scored between 650 and 670,with the least being 620.Then, I started to attempt expert global mocks.I found the quant and IR sections of the product to be best in the lot.However,in case of verbal,I found that the RC was bit off and often lengthy and different from those of gmac tests. I scored an average of 670 in mocks,with 630 being the least and 730 being the highest.

I took the original exam at the test center and scored a 630(Q47,V29).My quant score was representative of the average scores in expert global mocks but my verbal score deviated from the average score in the expert global mocks-it was 35 on average.

All in all, considering that no test prep company can simulate the algorithm of actual gmat test, expert global mocks are the best in terms of value and price, especailly for quant.
