Hi gmatxsurf,
If you have not taken any additional practice CATs yet, then the next step would be for you to take the 2nd (free) Official GMAC CAT sometime soon so that we can get a better sense of your current skills, strengths and weaknesses. Make sure to take it in a realistic fashion that matches-up with what you will face when you take the Official GMAT (take the FULL CAT - with the Essay and IR sections, at the same time of day as when you'll take the Official GMAT, if you will be at a Test Facility, then wear a face mask, etc.). Once you have that Score, you should post back here (or you can feel free to PM me directly) and we can discuss the results and how you might best proceed with your studies.
Going forward, you have to be careful about confusing "quantity" of study with "quality" of study. I've never asked anyone to study 30+ hours a week - and while it's great that you might have the available time to study that much, with that number of study hours, you would run the risk of 'burning out' before Test Day (and that is something that we want to avoid). If you are going to try to study that much, then I suggest that you take one hour "off" for every two hours of study. For example, you could study for 2 hours, then stop for an hour, then study for another 2 hours, then take an hour off, etc.
GMAT assassins aren't born, they're made,
