Do I need to prepare anything in advance?

No special preparation is needed, but here are a couple of things that will help:

A private / quiet space: We recommend completing the questionnaire somewhere private and quiet where you will not be disturbed, particularly as one section gives you the option to record short spoken responses. This is entirely optional and you can type your answers instead if you prefer.

Headphones or speakers: One section of the questionnaire involves listening to a recording, so you will need to be able to play audio on your device. You might need headphones or speakers to ensure you can hear properly.
