6CS028 – Component 2 (Alternative Assessment)

This assignment is worth 50% of the overall module grade

Introduction

This assignment will assess your knowledge of the theoretical concepts relevant to advanced web development discussed in the lectures.

The marking scheme for this task is available below, make sure you check back on a regular basis as you work through the assessment.

This task should be completed on an individual basis. Note, all submissions will be run through the Turnitin plagiarism detection software. Cheating, plagiarism or collusion will result in the student being referred to Conduct and Appeals.

Cheating is any attempt to gain unfair advantage by dishonest means and includes plagiarism and collusion. Cheating is a serious offence, and rigorous checks will be conducted on the work submitted. You are advised to check the nature of each assessment.

Plagiarism is defined as incorporating a significant amount of un-attributed direct quotation from, or un-attributed substantial paraphrasing of, the work of another.

Collusion occurs when two or more students collaborate to produce a piece of work to be submitted (in whole or part) for assessment and the work is presented as the work of one student alone.

Feedback

Feedback should be available within three working weeks. If you have any questions regarding your feedback you should contact and discuss the matter with the module leader. However, please note that due to exceptional circumstances, it may take longer than normal to provide feedback at this time.

Retrieval of Failure

Where a student fails a module (less than 50% for postgraduate modules) they have the right to attempt the failed assessment(s) once, at the next resit opportunity (normally July resit period).  If a student fails assessment for a second time, they have a right to repeat the module.

NOTE: Students who do not take their resit at the next available RESIT opportunity will be required to repeat the module.

Penalties for Late Submission

Standard Faculty of Science and Technology arrangements apply. ANY late submission (without valid cause) will result in 0 marks being allocated to the coursework.
