I called ETS today. They made a mistake. The essay score should be 6.0. Finally relieved! So everyboday here just come down. The grading policy can't be changed without notification. Thank you chasedream and every warmhearted xdjm here! If I can be of any further help, just send an e-mail to my chasedream mailbox.
To sh710 I wrote my essay by keyboard inputing. I think maybe you can check your score after a month or so. Not sure. You can check with the bullitin to get an accurate date.
