Practice feedback survey
Optional: after marking, tick the main reason for each mistake (you can tick more than one if it helps). Count the ticks in each column and write the totals in the bottom row—patterns here make revision easier than a score alone. When printing, this survey starts on its own page so you can skip that sheet in the print range if you do not need it.

- Didn't Understand the Concept
- The underlying idea or method was unclear—worth revisiting explanations or examples before more drill.
- Misread the question
- The topic was familiar, but a detail was missed (e.g. “not”, units, or what exactly to find).
- Calculation Error
- The approach was reasonable, but arithmetic, copying a figure, or a single step was wrong.
- Partial Step Error
- Working started correctly but went off track part-way—often a wrong operation or missed step.
- Wrong Option Marking
- The working or thinking pointed to the right answer, but the wrong letter was circled or recorded.
