Dear Sir/Madam
Re : (學生名字及班別)
As I intend to take up a part-time job in the morning, I would like to enquire about the possibility of changing my son from afternoon class to morning class. I would be much grateful if you would accept our application.
Kindly notice me of your decision. Thank you in advance for your kind consideration.
Yours faithfully
