LAHORE A petition has been filed in the Lahore High Court praying for the postponement of next upcoming matriculation exams on the ground that the Board has changed the pattern of the objective-type papers whereof the candidates need to be expert in drawing. The plea has been moved by Azhar Siddique in his already pending petition. He contends all Boards in Punjab have changed the procedure and pattern of objective type questions for the matriculation exams which would start on March 7.
