Hi Sent, I suggest that you study as you see fit for the next 2 weeks, then take one of the Official GMAC CATs (make sure to take the FULL CAT - including the Essay and IR sections). That score result will provide some important information about how well you're studying on you're own. Thanks Rich!...
