Sample report · independent-school maths paper, sat timed
31 of 42 correct — 10 marks recoverable
The score looks fine. The pattern doesn't. 11 lost marks sit in 3 clusters, and a mark scheme alone would name none of them.
Where the marks went
-
Ratio and proportion
4 of 7 lost · +4
Scaled one part of a two-part ratio and forgot the other. Classic on "for every 3…" stems.
-
Fractions (non-unit)
3 of 6 lost · +3
Multiplied where the question needed division. Unit fractions were fine — it's the invert decision.
-
End-of-paper checking
3 of 8 lost · +3
All three in the last eight questions. Right method, dropped digit.
