Mark scheme (a)

Scheme	Marks	Comments
Ystwyth 600 (points) AND Taf 300 (points)	B3	B2 for Ystwyth 600 or Taf 300 OR B2 for Ystwyth 300 AND Taf 600 B2 for 2 numbers that add to 900 B1 for sight of 1970 – 1070 or 900

Mark scheme (b)

Scheme	Marks	Comments
Any two suitable reasons e.g. “Conwy should be 10” “Conwy bar height not correct” “Taf has 1 bar, others have 2” “Different width bars” “scale not correct” “No gap between bars” “vertical label missing” “no title”	E2	E1 for each reason Allow “(The scale) should go up in 10s…..or 5s” “The numbers jump from 10 to 30” “The bars are too close together” “The numbers aren’t going up in the right order” Do not accept “They are not spaced out “They are not in order”

Corrected by Westie's Workshop

The board's mark scheme printed “Conway should be 10”. Changed to “Conwy should be 10” because the house is called Conwy in the question and in the next line of the scheme.
