TuitionGoWhere Exam Practice (AI) — SA2 Geography Secondary 1 (Version 4) Answer Key
Total Marks: 60
Section A: 20, Section B: 20, Section C: 20 — adds to 60.
Section A: Map Reading
1. [1] 2251
Teaching: 4-figure grid reference = easting (across, left-to-right) first, then northing (up). X is in square with lower-left at 22 east, 51 north. Common mistake: writing 5122 (reversed).
2. [1] 233524 (acceptable 233524–233525)
Teaching: 6-figure = 4-figure + 3rd digit easting (tenths) + 3rd digit northing. Y at 233 east, 524 north. Estimate tenths from position in square.
3. [1] 10 m
Teaching: Contour interval = difference between adjacent labelled contours (20–10 = 10). Not map scale.
4. [2] Approximately 045° (north-east)
Teaching: Draw north line from X, measure angle to Y (NE direction). 1 mark direction, 1 mark reasonable bearing. Common: using south as up.
5. [2] 1.6 km
Working: Map dist = 3.2 cm. Scale 1:50,000 → 1 cm = 0.5 km. Ground = 3.2 × 0.5 = 1.6 km. Show substitution and unit.
6. [1] 2153
Teaching: H at square lower-left 21 east, 53 north.
7. [2] A 4-figure gives the grid square (100 m accuracy at 1:50k); a 6-figure gives a point within the square (100 m or better).
Marking: 1 mark each for accuracy and precision difference.
8. [2] Student reversed order (northing before easting). Correct is 2251.
Marking: 1 mark identify reversal, 1 mark correct reference.
9. [1] 1:50,000
Teaching: 1 cm = 0.5 km = 50,000 cm → ratio 1:50,000.

16. [1] S (5%)
17. [2] Range = 60 – 5 = 55%

Marking: 1 mark point, 1 mark accuracy.
31. [1] Easy comparison of values.
32. [2] 205 – 98 = 107 mm
