For VIP user grading: e-grader, advanced module of e-grader, and human graders. The advanced module of e-grader will compare the performance of top users and get the score. Human graders will check ideas, logic connections, and thinking.

Final scores = (e-grader + advanced module of e-grader + human graders)/3
