- The practical — Audacity Project
- Cut-and-paste a section of music into a new project
- Edit the section so that the beginning and end match
- Loop the section
- Fade in and out
- Export the file

The Practical
The practical will be a timed exercise in creating an MP3 file using Audacity. It will be given in lab and will be similar to the Audacity labs.
The Ordinary
The ordinary exam will be closed-book and closed-notes with short-answer questions.
