GMAT Strategy

Hi Experts,

Last week I posted 2 of my recent test results from veritas prep tests in those I scored 700 and 710. Brian Gavin from veritas and Rich from empower gmat gave me very valuable advice. Now concentrating on those advices and improving my weak areas, I gave another Mock test from Kaplan and I scored 740. I had given kaplan tests before too but generally found very tough. Now what can I conclude from these results. My target score is 700+ anything 700+ will do because australian colleges generally have average gmat mean of 660 but I want to be on safe side. With these results can I be sure that I will get 700 on real GMAT.

Please have a look at my attached score card and please advice me as to what should I do in the next 13 days. Should I keep giving mock tests or practise my weak areas.

Thanks
