What GasTheory focuses on
Everything here is built to reduce overwhelm and increase pass confidence.
Accurate & Up-to-Date Gas Content
Lessons and questions are written to reflect current UK gas legislation, industry standards and manufacturer guidance — organised the same way you’ll see them in real training.
The goal: clear explanations that match how gas is assessed in college, on-site and in formal qualifications.
Questions Built for Real Learning
No “spot the pattern” quizzes. Question sets stay challenging, even after multiple attempts — so you learn the concept, not the answer order.
- Correct answers are randomly positioned.
- Questions you miss are shown first next time.
- Options are balanced so nothing is “obvious”.
- Instant explanations help you correct mistakes fast.
