Description
Revision for the F-Gas Category 1 exam (City & Guilds 2079 or LCL). Ten minutes in the van between calls is enough for ten questions, and F-Gas Study holds over 450 of them, so revision fits into the day rather than waiting for an evening you were never going to get. The questions cover all four sections: Basic Thermodynamics, Environment and Regulations, Refrigeration Practices, and Alternative Refrigerants. Pick one and run through five, ten, or the lot. You can narrow it to the questions you haven’t seen yet, or the ones you got wrong last time. There’s a full mock paper as well: 40 questions, 80 minutes, 75 per cent to pass, with the clock optional. Scores are tracked by section and topic, so you can see what still needs work rather than guessing at it. Works offline, no account. Five questions in each section are free to try. F-Gas Study is an independent revision aid, not affiliated with any awarding body.
