OLSAT Practice Pack — Grade 7

Answer Key — OLSAT Grade 7

1. 1. B — The sentence suggests collaboration, and 'teams' is the most suitable option for group work.
2. 2. D — The relationship is "what it grows or turns into." tadpole → frog, so bud → flower.
3. 3. E — Four of the five words are alike: they are parts of a triangle. circumference does not fit that group.
4. 4. B — Four of the five figures share one property: every figure is an outline (unfilled). B is the one that does not belong (repeats an exemplar's shape but breaks the shared property).
5. 5. D — 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 D. The others: A follows the column rule but not the row rule; B follows the row rule but not the column rule; C applies the change one time too many; E copies the far corner.
6. 6. E — In the top row, the figure's fill darkens one step and the figure shrinks. Applying the same change to the bottom figure gives E. The others each make a specific mistake: A right change, wrong figure shape; B applies a different rule than the top row shows; C applies only one of the two changes; D copies the top row's result instead of transforming the bottom figure.
7. 7. A — Each step, the figure alternates big and small. Continuing one more step gives A. The others: B the right figure with the wrong fill; C the right step on the wrong shape; D jumps two steps ahead; E does not continue the series.
8. 8. D — The amount added grows by 1 each step. Adding 6 to 14 gives 20.
9. 9. E — In every group the second number is 2 times the first, and the third is 7 less than the second. Applying the same rule to the last group gives 1: E.
10. 10. B — Across each row the numbers are multiplied by 3, and down each column they change by 2. The empty space must fit both its row and its column, which gives 1038: B.
11. 11. A — The sentence implies a central location, and 'center' is the most logical option for a city's historic area.
12. 12. A — The relationship is "worker to their workplace." pilot → cockpit, so sailor → ship.
13. 13. B — Four of the five words are alike: they are figures of speech. chapter does not fit that group.
14. 14. A — Four of the five figures share one property: all figures are the same shape AND the same fill (only the size and the dot vary). A is the one that does not belong (solid black instead of the shared property).
15. 15. C — In this grid going across each row, the figure alternates large and small and the figure turns a quarter-turn clockwise at every step. The empty box must satisfy both its row and its column, which gives C. The others: A repeats the figure to the left of the empty box; B repeats the figure directly above the empty box; D copies the far corner; E the right change on the wrong shape.
16. 16. E — In the top row, the figure doubles and the figure grows. Applying the same change to the bottom figure gives E. The others each make a specific mistake: A copies the top row's result instead of transforming the bottom figure; B applies a different rule than the top row shows; C the bottom figure with no rule applied; D applies only one of the two changes.
17. 17. B — Each step, the figure turns a quarter-turn each time. Continuing one more step gives B. The others: A steps backward in the series; C jumps two steps ahead; D repeats the last figure instead of stepping on; E the right step on the wrong shape.
18. 18. C — These are square numbers: 3², 4², … Next is 7² = 49.
19. 19. C — In every group the second number is 5 times the first, and the third is 10 less than the second. Applying the same rule to the last group gives 11: C.
20. 20. B — Across each row the numbers change by 6, and down each column they change by -6. The empty space must fit both its row and its column, which gives -1: B.
