WE WANT JUSTICE!! Class 10 CBSE maths paper

This year's class 10th Maths paper particularly Set : 1 had many tough questions which were very time consuming. My particular set had code no 30/4/1 .This set had a question in the 4 marks section (Q-24) was very difficult.
CBSE can solve this problem by giving 10 grace marks to all Set :1 students or by conducting a re-exam
