Your answer, working and self-marks

Read the original question, write your response here or in your notes, then compare it with the published marking instructions. Press Save my attempt to keep your response; typing alone does not save it. These are your own marks, not a verified result. Leave your marks empty to record an unmarked attempt; if you enter a mark, include its total.

Up to 12,000 characters. Diagrams and handwritten work can stay in your own notes.

Use the label in the PDF, not its viewer page number.

Method guide · plan your approach

Original ScotSpark strategy guidance, not an official model answer or a question-specific worked solution. Skill matching is provisional; use only the advice relevant to the actual question.

  1. Identify the practical decision, the data supplied and any units or assumptions.
  2. Choose the appropriate numerical, statistical, financial or planning method. Retain intermediate precision and show how the data enter the calculation.
  3. Interpret the result in context. Check the required rounding, constraints and any supplied spreadsheet or software files.

  • Pay, tax and deductions

    Apply the supplied bands, allowances or rates rather than current real-world assumptions.

  • Savings, annuities and schedules

    Track interest, deposits and timing consistently.

  • Percentages and compound change

    Choose the correct baseline and distinguish repeated change from a single change.
