Paper 2 shares no questions with Paper 1, and none with our lessons either. That matters more than it sounds: re-sitting questions you have already met measures how well you remember them, not how well you know the regulations. A second genuinely independent paper is the only honest way to tell whether a week of revision moved anything.

All three papers are dealt to the same blueprint, so Paper 2 is a like-for-like re-measurement rather than a different exam: the same weighting across navigation, protection, selection and erection, inspection and testing, special locations and the Amendment 4 ground. If Paper 1 exposed slow navigation, sit this one with the book closed on the first pass and only open it when you are genuinely stuck; the contrast tells you what you actually know.

Pacing target: twelve questions every twenty-four minutes. If you are behind at the halfway mark, you are almost certainly over-reading the stem. Most 2382-26 questions are decided by one word — a rating, a location, a Part number.

  • Regulation lookup speed
  • Protection for safety and selection and erection
  • Inspection, testing, special locations and Amendment 4:2026

Common questions

How long is 18th Edition Mock Exam 2 and how many questions?
60 multiple-choice questions in 120 minutes, each one answer from four options, which is the C&G 2382-26 shape. That is two minutes a question, and the paper is open book — you may consult BS 7671 throughout, exactly as you can in the real assessment. None of the questions appear in our lessons.
What is the pass mark for 18th Edition Mock Exam 2?
60% — 36 of 60 — which is the mark the real C&G 2382-26 assessment is set at. Your result is broken down by area afterwards so you can see which ground to revisit.
Do I need TradeTraining Premium for 18th Edition Mock Exam 2?
Yes. Paper 1 is the free full-length mock; papers 2 and 3 are part of Premium, along with unlimited retakes, worked reasoning on every question and spaced-repetition review of what you missed.
How many mock exams should I sit before the real thing?
Two or three full-length papers is usually enough, spaced across your revision rather than crammed into the last night. What earns the marks is reviewing every question you got wrong and finding it in the book — the sitting is diagnosis, the review is treatment.
Do the mock papers share any questions with each other or with the lessons?
No. The three papers are disjoint: 180 different questions, none of them repeated between papers and none of them used in a lesson. That is deliberate — a mock is only a prediction of your result if the questions are ones you have not already answered and had explained.
