How you will use it
Practise the way that suits you
- Learn as you go. Answer, read why straight away, then move on. No clock, no pressure.
- Or sit it timed. A clock, no answers until the end, and two minutes a question, so you learn to pace yourself.
- Score by topic. See which area let you down instead of one number out of a hundred.
- Go back over it. Read every question again afterwards, right and wrong, with the full explanation.

People rolling Copilot out across an organisation
A quarter of it is policy, content exclusions, audit logs and subscription management.
Anyone who has to answer for how the tool handles code
Data flow, output ownership, public code filtering and responsible use are examined directly.
