<p>If you order the Q & A service, then the direct affect of your essay to your overall Writing score will be shown through a table. For example, they will have your multiple choice subscore on the y-axis and the essay score on the x-axis. Match your two scores together and that should be your writing score. Then with the same subscore, match it with a 6 essay (one higher than yours) and see how much it would have affected your score if you had gotten a 6 instead of a 5. I'm pretty sure each test has a different table for the writing score. The one downside to this is that Q/A service comes centuries after the test.</p>
