Mrs. Payal Makhija, teacher of class 9 and 10, was very helpful in making this event the success it was and she was the only Maths Teacher from the school to attend the event (unlike the first one, which was attended by 4 Maths teachers) as the organisers were able enough to manage the students and did not need any help from the teachers.
