Just a quick update guys thanks for your advice, I have my exam in 1 week now and recently I have been using the following resource...
Download VMWare.Lead2Pass.VCP-510.v2013-06-13.by.Riot.369q.vce
as a practice exam since feedback seems positive. The strategy I have been following in this last week has been to obsessively and continuously do the exam and go off and research a subject matter further and in more detail when I get the answer wrong. My only concern however is that I typically only seem to get 60%-65% of my questions in the mock correct. consequently I am finding this a little concerning, I know the exam is scored on scale but my quoted percentage seems concerning to me. Does anyone have even a rough stab in the dark guess as to how many you can afford to get wrong?
