These pages give examples of the type of work you need to do for each section of your project and report.

The examples come from many different projects. They can not be combined to make an AS Report!

The codes like Aa, Bd, Cb are used for marking your work. These are each worth 2 marks if you complete them properly and don't leave out important work.

Section A is for planning, design and most importantly - write a good specification including planned tests.
Section B is for building subsystems, testing the inputs and outputs and explaining how the subsystems work.
Section C is for testing the complete circuit and most importantly - complete the planned tests from your specification.
Section D - Make sure you have a good Bibliography. Otherwise no more writing is needed but marks are given for ...

Practical Investigations

Not all the projects above have obvious or sensible practical investigations.
Here are some fairly straightforward practical investigations that might be useful in some of the projects ...

  1. How loud does the sound need to be?
  2. What is the output voltage of the Electret microphone for normal speech?
  3. What is the best buzzer audio frequency to use?
  4. What is the resistance of the LDR at XXXX Lux?
  5. What value is XXXX Lux?
  6. What is the resistance of the Thermistor at XXXX degrees?
  7. How long does it take to boil an egg?

Cover sheet / declaration

Coursework submitted in hardcopy must be attached to a Coursework Submission Cover Sheet.

Coursework submitted electronically must include a Coursework Declaration.

Your submission should be anonymous and identified only by your candidate number. Do not write your name anywhere on your work or on the cover sheet / declaration.

Plagiarism and collusion

In submitted coursework all sources used must be cited appropriately to avoid plagiarism. All work, unless explicitly labelled otherwise, must be submitted individually; similar/identical submissions will be investigated for collusion. The Academic Office has published some excellent, general advice to students on how to avoid plagiarism and collusion, including definitions of the terms plagiarism and collusion.

Place of submission

All assignments, whether they are formally assessed or not, must be submitted to the Engineering and Informatics School Office, unless otherwise indicated. Please look out for any announcements about submission location. Any assignment that has not been entered on the electronic submission system will count as a non-submission and will normally attract a fail mark.

Policy on re-submission of assignments after the deadline

Students should note that the School of Engineering and Informatics has adopted the following policy regarding re-submission of assessed coursework assignments.

No re-submission of assignments will be permitted after the submission deadline. Prior to the submission deadline, resubmission is permissible.

Note that this policy applies to both submission via the School Office and electronic submission.

Deadlines for submission / timing of examinations

Submission deadlines and examination timetables can be found on your Sussex Direct pages.

Late submission

No work can be accepted more than 7 days after the submission deadline.

Exceptional circumstances for late submission or impaired performance

If you feel you have compelling evidence of exceptional circumstances for submitting late or for impaired performance, please contact the Student Life Centre.

It is important that you organise your time effectively so that all assessed work – especially your dissertation – is submitted on time. Note that failure of your computer or loss of data on a disk is not regarded as an acceptable reason for late submission. So if your assignments require the use of computers, either for programming or document preparation, please make sure you are not dependent on them, particularly when submission deadlines are close.
