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.

Weekly score trend
Spot improvement or dips early—keep 11+ prep consistent week to week.
Answer mix (correct · incorrect · not sure)
See confidence gaps—not just the headline score after each session.
Speed vs accuracy
