Aim for 23 of 30: 22 of 30 is under 75%.

What you can take in

  • IET Code of Practice for Grid-connected Solar Photovoltaic Systems (2nd Edition)
  • BS 7671

Paper copies only. Check with your centre which edition of BS 7671 you may take in. The PV-specific requirements in Section 712 did not change in A4.

A calculator is allowed (non-programmable scientific).

The practical is assessed at your centre

You must also pass the unit 302 practical assignment, set by City & Guilds and marked at an approved centre. This course teaches the knowledge behind it; it can’t deliver or mark it.

What’s inside, weighted like the exam

City & Guilds publishes how many of the 30 questions come from each learning outcome. Every module is mapped to them, so each tab is as long as its share of the test and every full mock follows the same split. Modules marked “Practical only” teach the knowledge behind what your centre assesses.

Example readiness score of 72 out of 100, “Nearly there”: exam ready needs 80 or more and a passed full mock.

A readiness score that doesn’t flatter you

We don’t call you exam ready until your score is 80 or more and your latest full 30‑question mock is a pass. The real pass mark is approx. 75%, so you go in with a margin.
