Attention to: The Department Head / The Headmaster Dear Sir / Madam, I am XXX (名字) of Class YYY (班号), I would like to apply for a shift from my current class to other class. I find myself having difficulties in handling the over-whelming assignments and course works in this class especially the Physic subject, I also find it tough to comprehend what the Physic teacher is trying to say most of the time. I humbly seek your approval to relocate me to other class so that I can learn at a more comfortable manner. Your approval to the above is much appreciated. Thank you. Yours faithfully. XXX
