Important Information

You are required to submit your work within the bounds of the University Infringement of

Assessment Regulations (see your Programme Guide). Plagiarism, paraphrasing and

downloading large amounts of information from external sources, will not be tolerated and

will be dealt with severely. However, you should make full use of any source material, which

would normally be an occasional sentence and/or paragraph (referenced) followed by your own

critical analysis/evaluation. You will receive no marks for work that is not your own. Your

work may be subject to checks for originality which can include use of an electronic

plagiarism detection service. Where you are asked to submit an individual piece of work, the

work must be entirely your own. The safety of your assessments is your responsibility. You

must not permit another student access to your work. Where referencing is required, unless

otherwise stated, the Harvard referencing system must be used (see your Programme Guide).

Please ensure that you retain a duplicate of your assignment. We are required to send

samples of student work to the external examiners for moderation purposes. It will also

provide you with a safeguard in the unlikely event of your work going astray.

Submission Date and Time Friday 9th March 2018, by 4:00pm
