- Self-check questions with answers (8)
Specification: P3.6-3.7. Codes follow the UAT-UK ESAT content specification.
How to use it
- Read a section, then cover the worked example and try it yourself.
- Check the common mistakes list: these are the slips the real test is built to catch.
- Do the self-check without looking back. Mark it against the answers.
- Then practise the topic under time, with the matching practice set.
