Of the four written assignments, two are to be written to an Academic standard and all need to have a bibliography and to be referenced correctly.
It is often the case that written assignments have to be re-submitted. This may be because of the content, or perhaps because the English used is not quite to standard and sometimes it might be because of both. In this scenario, the assignment is given back to you with clear, written comments from the tutor specifying which sections or problematic areas need to be addressed.
There is one opportunity to resubmit and all assignments simply carry a Pass or Fail grade.
