Revision guide
Common reasons students lose marks despite a sensible method
A response can begin well and still lose marks in execution or communication. Classifying the exact loss leads to a better correction than writing 'careless'.
Execution errors
- Sign or arithmetic slip
- Premature rounding
- Calculator mode error
- Incorrect substitution
- Dropped solution or case
Communication errors
- Missing units
- Unsupported conclusion
- Unclear construction or graph scale
- Answer not given in the requested form
- Working overwritten beyond recognition
Replace 'careless' with a cue
Write a specific check such as 'substitute both roots', 'write the multiplier before calculating' or 'check whether area units are squared'.
