First, let me welcome you to the GMATclub!
I really wouldn't worry about it. As you already know, there is a human grader, a computer grader, and two essays. The human and computer grades are averaged and then the two essays are averaged. This is where it stops right? WRONG...
There is a little known fact though that I think may come into play on your essay. If the human and the computer grade is more than 1 point different, a 3rd grader comes into play. This 3rd grader is another human, and takes the place of the computer's grade. So if the computer totally kills you for the notes, and the human grader will obviously know they are notes and the two grades will differ, then the 2nd human will also grade. I will guess this will not affect your score much at all, if any. Here is the direct quote from GMAC:
Quote:
The Analytical Writing Assessment (AWA) section of the test consists of two essays. In the first, the student must analyze an argument and in the second the student must analyze an issue. Each essay must be written within 30 minutes and is scored on a scale of 0–6. The essay is scored by a human and by a computer program; each scorer marks the essay with a grade from 0 to 6. If the two scores differ by one point or less, they are averaged. If the two scores differ by more than one point, the essay is scored a third time by a human reader.
The first scorer is "IntelliMetric", a proprietary software by Vantage Learning, which purports to analyze creative writing and syntax by using a number of linguistic and structural features. The second and third readers are humans, who evaluate the quality of the examinee's ideas and his ability to organize, develop, and express ideas with relevant support. While mastery of the conventions of written English factor into scoring, minor errors are expected, and evaluators are "trained to be sensitive and fair in evaluating the responses of examines whose first language is not English."
Come back and let us know how you did! I would try not to worry about it, b/c as long as you score above a 4.0 on the AWA the schools won't even take a look at the AWA. Especially since the GMAT is being changed in a few months anyways since it was obvious that the AWA was pretty useless to Adcoms.
