Pass the FROSIO exam — practise it the way it's examined
The FROSIO theory exam is written, not multiple-choice — you produce answers, you don't recognise them. CoatMentor is built for exactly that: 240+ original open-answer prompts with model answers, three timed 4-hour written mocks, and AI-assisted key-point marking. No braindumps, no recycled exam questions.

Why multiple-choice prep fails for FROSIO
Recognising the right answer is a much lower bar than producing it on paper under time pressure. Generic MC question banks train the wrong skill — that's the gap this track exists to close.
Write first, then compare
Every prompt locks the model answer until you've written yours. Then you compare against the model answer and its key points — the exact discipline the written paper demands.
Timed 4-hour written mocks
Three 80-prompt mocks drawn to the syllabus topic weights — inspection & reporting, application, corrosion, surface prep, coatings, calculations, standards, climate, H&S — at the real exam length.
AI-assisted marking, you decide
After a mock, AI pre-ticks the key-point checklist for each of your answers; you review and keep final say. If AI marking is ever unavailable, self-marking against the key points always works.

- Sa 2½ = very thorough / near-white
- Sa 3 = visually clean steel
- Sa 3 is the higher grade
