Section B

1 Explain what is meant by an OCR-set assignment that is centre-assessed and OCR-moderated. 3

One mark for each of the following, to a maximum of 3.

  • OCR writes the assignment and its tasks
  • The centre's teachers mark the work against OCR's criteria
  • OCR checks a sample of the marking against the national standard

Model answer. An OCR-set assignment is a brief written by OCR, with a scenario, a client and tasks, which every centre uses rather than writing its own. Centre-assessed means the work is marked first by the student's own teachers, using OCR's marking criteria. OCR-moderated means OCR then checks a sample of each centre's marked work, and adjusts the marks if the centre has been more generous or more severe than the national standard, so that a mark means the same thing in every school.

2 Explain why you must reference the sources you use in your coursework. 3

One mark for each of the following, to a maximum of 3.

  • It shows which work is yours and which is from others
  • Not doing so can be plagiarism or malpractice
  • It lets the reader check the source, or shows the data is reliable

Model answer. Referencing makes clear which parts of the work are your own and which come from other people, so you get credit for your own thinking and others get credit for theirs. Using someone else's words, images or data without saying so is plagiarism, which is malpractice and can lose you the marks or even the qualification. A reference also lets the reader find and check the source, which matters in a model whose assumptions rest on data: a demand figure taken from a named, reliable publisher is far more convincing than one with no source at all.

3 Describe what makes test evidence convincing in a spreadsheet modelling assignment. 4

One mark for each of the following, to a maximum of 4.

  • Tests planned in advance from the requirements, with hand-calculated expected results
  • A range of test data: normal, boundary, invalid and erroneous
  • Screenshots or formula views showing the actual results, annotated
  • Failures recorded with the cause, the fix and the retest

Model answer. Convincing test evidence starts with a plan written before the model was built, from the requirements, with every expected result worked out by hand so there is an independent answer to compare with. It uses a range of test data, normal, boundary, invalid and erroneous, so it shows the model rejecting what it should reject as well as calculating what it should calculate. Each actual result is backed by a screenshot or the formula view, annotated to say what it proves. And it records the failures honestly, with the cause, the fix and the retest, because a log where everything passed first time looks like a log written to pass.
