Just relax, listen, step up to the plate and prove what you know, there are no trick questions, but people,don't listen and choose to make a simple test more difficult, here's a scenario, it will be easier because you can read the instruction rather than hear it but you should get the message
"Ok here's what I want you to do, using your knowledge and working to the current regs and safety standards I want you to go into bay 1 and confirm by whatever means you see fit, whether the gas carcass meets current standards and would be safe to leave on, or take appropriate action to comply with the regs, remember it's an assessment and time is crucial, so keep in mind I want it done safely but as quickly as the regs allow"
Let's say two bays are identical and the instruction is given to two candidates at the same time,
A goes into bay 1 and comes out 6/7 minutes later and starts writing the report,
B goes into bay 2 and after 25 minutes the assessor goes in and asked what's happening, to find the candidate fixing and altering all sorts
A listened, went in, did a visual, did a TT, saw faults and found a leak out with permissable , he then capped the meter and came back out
B heard what he wanted to hear and proceeded to repair leaks, alter pipes and all sorts, because he was told "to work to the regs and leave it safe" he wasn't actually told to repair and bring up to standards was he
A bit of a long winded example but makes the point, do what is necessary and what is asked of you, not what you thought you heard
