The assessment for DU301 consists of six Tutor-Marked Assignments (TMAs) and a Course Essay. You should aim to complete all six TMAs, although the substitution rule means that you can omit one assignment. You must submit TMA 03, the double-weighted assignment. (The substitution system is explained in Section 2.3.) It is possible in exceptional circumstances to ask your tutor for a later submission date for an assignment, but this can lead to problems with scheduling your work. We strongly advise you to submit your TMAs by the cut-off dates given in this Assignment Booklet and the Study Calendar.
