I agree with you very much. Many of my classmates or friends in our school may have experienced a change in grade by one point difference in the mock test. If you find out that they did their best on the test but didn't get a good grade due to a point difference, you can see more friends who will be disappointed or inconvenienced their grades than friends who are OK. I don't think it's a good idea to have an absolute evaluation that would make them lose their confidence if they didn't get elected to college by a point difference.
