AS Coursework

This is the AQA version closing after June 2019. Visit the the version for Eduqas instead.

To gain access to revision questions, please sign up and log in.

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?
