How 8-mark extended answers are marked, and how to discuss and recommend secondary storage for a device or an organisation.
What you will learn
- Explain how levels of response are marked
- Compare magnetic, optical and solid state storage for a scenario
- Recommend storage and justify the choice
How an 8-mark answer is marked
Longer 8-mark questions are marked by levels of response, not by counting points.
The marker reads the whole answer and decides which level it fits, then where in that level.
- Level 3 (7 to 8 marks): thorough, accurate knowledge applied to the situation throughout. Both sides are discussed and developed, and the conclusion follows from the points made.
- Level 2 (4 to 6 marks): sound knowledge, mostly applied to the situation, with some discussion, but it may be one-sided or the conclusion may not be supported.
- Level 1 (1 to 3 marks): basic knowledge with little link to the situation. Points are listed rather than explained.
A list of correct facts with no link to the scenario stays in Level 1, however long it is. Every point should say what it means for this organisation or this device.
The questions here are written by Brainlag in the OCR style for practice. None is taken from an exam.
The rest of this lesson and its 8 practice questions are locked.
