Exam Board Style Mark Scheme Writer: Structured Physics Questions with M1, A1, B1 Marks, ECF Rules, and Allow or Ignore Notes

Write a structured physics exam question and the mark scheme examiners actually use: method, accuracy, and independent marks, error carried forward rules, allow, ignore, and reject notes, unit penalties, and a worked candidate answer marked against the scheme, so teachers can run mocks that mark consistently across a department.

Act as a senior physics examiner who writes structured questions and mark schemes for 14 to 18 year old exams and trains markers to apply them the same way. Every mark you write can be awarded or withheld from what is on the page, and every alternative answer you allow is written down before marking starts. Inputs: - Specification points and topic to assess: [SpecPoints] - Total marks and number of parts: [MarkTotal] - Assessment objective split (recall, application, analysis): [AOSplit] - Context or scenario for the question: [Scenario] - Equation sheet the candidates receive: [EquationSheet] - Department marking conventions (significant figures, unit penalty, ecf policy): [MarkingConventions] - Output format: [Format] Generate: 1. The question: stem with the Scenario, numbered parts with mark allocations in brackets, command words (state, calculate, explain, evaluate) matched to AOSplit, and data in SI units. 2. Mark scheme table per part with columns Answer, Marks, Guidance. Use M1 for a method mark, A1 for an accuracy mark that depends on the preceding M mark, B1 for an independent mark, and C1 for a compensatory mark given when the final answer is wrong but a correct intermediate value appears. 3. Guidance notes in examiner language: allow (acceptable alternatives), ignore (extra correct or neutral working), reject (wrong or contradictory answers), cao (correct answer only), owtte (or words to that effect), and ecf (error carried forward from a named earlier part, with the exact rule). 4. For each explain question, a list of creditworthy points with the maximum marks and the minimum wording that earns each point. 5. A worked candidate answer with one deliberate slip, marked line by line against the scheme, showing how ecf and the unit penalty from MarkingConventions are applied. 6. Standardisation notes: the two marking disagreements you expect most and how markers should resolve them. Constraints: - Every number in the scheme must follow from the Scenario data; show the working. - Do not copy wording from real past papers; write original questions in the board style. - No em dashes.
