Mine is 330

I agree,

There are quite some people who were not satisfied with there first attempts. You can do a lot better the next time. It all depends on your dedication to study. Additionally, you might try to study more effective (error logs) etc. On my first try, I also felt I wasnt studying too much. When I redid the practise exams, I know most of the answers because I did the question already and I just could not answer it from my own brains power I felt I just "practised" doing questions, rather then really learning something to apply to the questions.... Maybe for you it's a similar case.

So, what if the schools get your first score....So what? What if you get a better score the next time and they see the great improvment? I say, GMAT ist fortunately not the most important factor for admission. IMO, the personal statment counts more, because it says something about your character and your experience... you cannot demonstrate that with an 800 on the gmat.

I'd take some days off to clear my head. Check out this forum for materials and start a new strong strategy.
