Dear sir,
Assalamu Aliakum warahmatullah. I could not go to school last 7 days because of my physical illness. I heard that the date of our annual exam has been changed but I am not clear about the date. I would be grateful to you if you please inform me the exact changed date of the exam.
Wishing you best of luck
Sania.
