OLSAT Practice Pack — Grade 6

Answer Key — OLSAT Grade 6

1. 1. B — Walls that are impressively strong (formidable) are never broken through (breached). Thin or low walls would be easy to breach.
2. 2. A — The relationship is "worker to their workplace." doctor → hospital, so teacher → school.
3. 3. D — Four of the five words are alike: they are military ranks. uniform does not fit that group.
4. 4. C — Four of the five figures share one property: all figures share the same fill. C is the one that does not belong (matches the shapes but not the shared fill).
5. 5. E — In this grid going down the rows the fill darkens one step, and going across the columns the figure turns a quarter-turn clockwise. The empty box must satisfy both its row and its column, which gives E. The others: A repeats the figure directly above the empty box; B the right shape with the wrong fill; C follows the row rule but not the column rule; D applies the change one time too many.
6. 6. A — In the top row, a smaller copy appears inside and the figure's fill darkens one step. Applying the same change to the bottom figure gives A. The others each make a specific mistake: B applies the change twice; C copies the top row's result instead of transforming the bottom figure; D the bottom figure with no rule applied; E applies a different rule than the top row shows.
7. 7. D — Each step, the fill moves one step through the cycle (light to dark, then starting over). Continuing one more step gives D. The others: A the right step on the wrong shape; B repeats the last figure instead of stepping on; C the right figure with the wrong fill; E jumps two steps ahead.
8. 8. D — The amount added grows by 1 each step. Adding 5 to 10 gives 15.
9. 9. C — In every group each number is 4 times the one before it. Applying the same rule to the last group gives 80: C.
10. 10. C — Across each row the numbers are multiplied by 2, and down each column they change by 11. The empty space must fit both its row and its column, which gives 248: C.
11. 11. B — 'Though' contrasts looks with personality: they look identical but are completely different in character. 'Alike .. similar' gives no contrast.
12. 12. C — The relationship is "part to its whole." wing → bird, so room → house.
13. 13. A — Four of the five words are alike: they are kinds of rock. soil does not fit that group.
14. 14. A — Four of the five figures share one property: all figures are the same shape AND unfilled (only the size and the dot vary). A is the one that does not belong (the same shape, but a different fill).
15. 15. B — In this grid going across each row, the figure turns a quarter-turn clockwise and the figure alternates large and small at every step. The empty box must satisfy both its row and its column, which gives B. The others: A the right change on the wrong shape; C copies the far corner; D the right shape with the wrong fill; E repeats the figure to the left of the empty box.
16. 16. B — In the top row, the figure shrinks and the figure's fill darkens one step. Applying the same change to the bottom figure gives B. The others each make a specific mistake: A applies the change twice; C applies only one of the two changes; D right change, wrong figure shape; E copies the top row's result instead of transforming the bottom figure.
17. 17. D — Each step, the figure alternates big and small. Continuing one more step gives D. The others: A does not continue the series; B the right figure with the wrong fill; C the right step on the wrong shape; E jumps two steps ahead.
18. 18. A — The amount added grows by 1 each step. Adding 5 to 11 gives 16.
19. 19. E — In every group the second number is 12 more than the first, and the third is 5 times the second. Applying the same rule to the last group gives 100: E.
20. 20. A — Across each row the numbers change by 9, and down each column they change by -12. The empty space must fit both its row and its column, which gives 36: A.
