The total score of Item (2) of Question 22 is ***5, and the coordinates of point C are 3. If you can't find the coordinates of point B, you can only get 1.
The last small question is also ***5 points. If you do this, you will be deducted 4 points.
So together, you may be deducted 7 ~ 9 points.
I am also taking the senior high school entrance examination this year, and our teacher has worked out the grading rules.
But I am from Lianjiang, so I don't know your school in Changle.
