If your study centre does not have a specific paper size, you can use A4-size paper or assignment pages with lines marked on them. Mark the page number on your assignment and the total pages in front of your assignment, and if you submit any tables or images, mark them on your table of content.
When submitting your assignment, remember to include a copy of your assignment question as well as your name, enrollment number, submission date, course name and code, term, study centre address, as well as your address and contact number, so that study centre staff can contact you if anything goes wrong.
