Students must apply for a place before attending any class. Applications(申请), either by post or in person, are dealt with strictly in the order they are received at the Adult Education Office.
　　You can apply:
　　BY POST-Use the card provided with the exact fee. You'll be accepted on the course unless it is full, in which case we will inform you. An acknowledgement(承认) will not be made nor a receipt(收据) sent unless you provide a stamped addressed envelope. Receipts will normally be given out at the first class.
　　IN PERSON-Call at the Adult Education Office (ground floor, Block C) between approximately 9:00 a.m. and 3:00 p.m. (2:30 p.m. on Fridays), or at the College Reception Desk (at the main entrance) at the other times (in the evenings until about 7:30 p.m. on Fridays).
　　Students should note that popular classes may be full well before the course is to start, so that early application is strongly advised to avoid disappointment.
　　For the AUTUMN TERM, applications will be accepted by post (preferably) or in person from 1st August.
　　For the SPRING TERM, applications will be accepted from 1st December.
　　For the SUMMER TERM, applications will be accepted from 1st April.
