답을 선택하면 정답 여부와 풀이 과정을 볼 수 있습니다 — 가입이 필요 없습니다. 이는 현재 OC 형식으로 세 영역에 걸친 예시 문제이며, NSW 실제 기출문제가 아닙니다. 한 번에 몇 문제씩 푸세요; 빨리 끝내는 것보다 각 답을 이해하는 것이 더 중요합니다.
아래 샘플 문제는 영어로 표시됩니다 — OC 시험 자체도 영어로 치러집니다.
“The old lighthouse had not shone for thirty years, yet every evening Mrs Patel climbed its spiral stairs. She carried no lamp and lit no flame. Instead she sat by the great dark window with her notebook, counting the ships that slipped past in the dusk and writing down their names.”Why did Mrs Patel climb the lighthouse each evening?
Choose an answer to see how it’s worked out.That’s it.
Close — answer from what the passage actually says.
The passage tells us she carried no lamp and lit no flame, which rules out lighting it. It then says she counted the ships and wrote down their names — she was keeping a record. Inference means using what the text states, not what a lighthouse is usually for.
“She sat by the great dark window, counting the ships that slipped past in the dusk and writing down their names.”In this passage, the word “slipped” most nearly means:
Choose an answer to see how it’s worked out.That’s it.
Close — let the sentence decide the meaning.
“Slipped” has several meanings, but here the ships are moving past in the dusk, so it means moved quietly and smoothly. Vocabulary-in-context questions reward the meaning the sentence supports, not the most common one.
“Honeybees cannot see the colour red. To our eyes a field of red poppies looks bright, but to a bee the same flowers appear dull and grey. This is one reason bees visit blue and purple flowers far more often. Gardeners who want to attract bees are often advised to plant lavender rather than red roses.”Which sentence best states the main idea of the passage?
Choose an answer to see how it’s worked out.That’s it.
Close — the main idea is what every sentence supports.
Every sentence points to one idea: bees see colours differently, and that shapes which flowers they choose. Options A and D are single details, and B is an overstatement — none of them is the whole point of the passage.
“Honeybees cannot see the colour red… bees visit blue and purple flowers far more often. Gardeners who want to attract bees are often advised to plant lavender rather than red roses.”Based on the passage, a gardener who plants only red roses will probably find that:
Choose an answer to see how it’s worked out.That’s it.
Close — follow what the passage tells us about red.
The passage says bees rarely visit red flowers and advises lavender over red roses, so red roses would draw fewer bees than lavender. It never says roses can’t grow, and it states bees see red as dull, not bright.
“The scientist’s explanation was so clear that even the youngest student could grasp it.”In this sentence, the word “grasp” most nearly means:
Choose an answer to see how it’s worked out.That’s it.
Close — think about what is being grasped.
“Grasp” can mean to hold something in your hand, but here a student is grasping an explanation, so it means understand. The clue is the context — a clear explanation a student could follow.
“By the time Sara reached the bus stop, the road was empty and the timetable on the pole was wet with rain. She sighed, pulled her hood up, and began the long walk to school.”What can we most reasonably infer from the passage?
Choose an answer to see how it’s worked out.That’s it.
Close — read the clues the writer leaves.
The empty road, Sara’s sigh, and her setting off on the “long walk to school” instead of waiting all point to the bus having already gone. Nothing says she planned to walk, and the wet timetable shows rain, not sun. Inference means reading the clues, not just the stated words.
A baker makes 6 trays of muffins. Each tray holds 8 muffins. She sells 34 muffins in the morning. How many muffins are left?
Choose an answer to see how it’s worked out.That’s it.
Close — find the total before you subtract.
First find how many muffins there are: 6 trays × 8 = 48. Then take away what was sold: 48 − 34 = 14 left. The trap answer 82 comes from adding 48 and 34; do the multiplication first, then the subtraction.
Leo buys a book for $12 and a pen for $3.50. He pays with a $20 note. How much change should he receive?
Choose an answer to see how it’s worked out.That’s it.
Close — add both items before taking the change.
Add the two prices first: $12 + $3.50 = $15.50. Then subtract from the $20 note: $20 − $15.50 = $4.50 change. Adding both items before you subtract avoids the common slip of paying for only one.
A pizza is cut into 8 equal slices. Maya eats 3 slices and her brother eats 2 slices. What fraction of the pizza is left?
Choose an answer to see how it’s worked out.That’s it.
Close — the question asks what is left, not what was eaten.
Together they eat 3 + 2 = 5 slices out of 8, so 5/8 is gone. That leaves 8 − 5 = 3 slices, which is 3/8 of the pizza. The trap answer 5/8 is the part eaten, not the part left.
A film starts at 2:45 pm and runs for 1 hour and 40 minutes. What time does it finish?
Choose an answer to see how it’s worked out.That’s it.
Close — add the hour and the minutes in two steps.
Add the hour first: 2:45 → 3:45. Then add the 40 minutes: 15 minutes reaches 4:00, and 25 more makes 4:25 pm. Splitting the time into the hour and the minutes keeps it simple.
In a car park there are only motorbikes and cars. Altogether there are 7 vehicles and 22 wheels. A motorbike has 2 wheels and a car has 4 wheels. How many cars are there?
Choose an answer to see how it’s worked out.That’s it.
Close — start by imagining they were all the same.
If all 7 vehicles were motorbikes, that would be 7 × 2 = 14 wheels — but there are 22, which is 8 extra. Each car has 2 wheels more than a motorbike, so 8 ÷ 2 = 4 cars. Check: 4 cars and 3 motorbikes give 16 + 6 = 22 wheels.
Three identical books weigh 900 grams altogether. How much would 5 of the same books weigh?
Choose an answer to see how it’s worked out.That’s it.
Close — find one book first, then scale up.
Find the weight of one book: 900 ÷ 3 = 300 grams each. Then 5 books weigh 5 × 300 = 1500 grams. Working out the single value before multiplying is the key step.
Four runners finished a race: Kim, Lena, Mo and Sam. Kim finished before Lena. Sam finished after Lena. Mo finished before Kim. In what order did they finish, first to last?
Choose an answer to see how it’s worked out.That’s it.
Close — chain the clues into one line before choosing.
“Mo before Kim” and “Kim before Lena” give Mo, Kim, Lena in that order. “Sam after Lena” puts Sam last. Joined up, the finish order is Mo, Kim, Lena, Sam. Lining every clue up before you answer is what these puzzles reward.
In Mr Roy’s class, every child who plays chess also plays the violin. Dev does not play the violin. Which statement must be true?
Choose an answer to see how it’s worked out.That’s it.
Close — follow the rule, don’t add to it.
If every chess player also plays the violin, then anyone who does not play the violin cannot be a chess player. Dev does not play the violin, so Dev cannot play chess. The other options add facts the statements never give.
Anya, Bo and Cara each have a different pet: a cat, a dog or a fish. Anya is allergic to fur, so she has neither the cat nor the dog. Bo takes his pet for walks. Which pet does Cara have?
Choose an answer to see how it’s worked out.That’s it.
Close — settle the pets you can be sure of first.
Anya can’t have fur, so she has the fish. Bo takes his pet for walks, so Bo has the dog (the fish is taken, and you don’t walk a cat). That leaves the cat for Cara. Fixing the certain pets first leaves the last one by elimination.
A poster reads: “Drink FizzyBerry — the most popular fizzy drink at Sunfield School!” The poster wants you to believe FizzyBerry is a good choice. Which assumption does the poster rely on?
Choose an answer to see how it’s worked out.That’s it.
Close — find the missing link in the argument.
The poster jumps from “most popular” to “good choice”. That only works if being popular actually makes something a good choice — the unstated assumption. The other options may be true, but the argument doesn’t depend on them.
Ravi says his new running shoes made him faster, because he ran his best-ever time the first day he wore them. Which statement, if true, would most weaken Ravi’s claim?
Choose an answer to see how it’s worked out.That’s it.
Close — look for another cause of the fast time.
Ravi assumes the shoes caused his fast time. If a tailwind pushed him the whole way, that — not the shoes — could explain the best time. Pointing to another likely cause is the strongest way to weaken a “this caused that” claim.
Look at the number pattern: 1, 4, 9, 16, 25, … What is the next number?
Choose an answer to see how it’s worked out.That’s it.
Close — look at how the gaps grow.
Each number is a square: 1×1, 2×2, 3×3, 4×4, 5×5, so the next is 6×6 = 36. You can also see the gaps grow by 2 each time (+3, +5, +7, +9, then +11), and 25 + 11 = 36.
연습을 가장 잘 활용하는 방법
차분하고 정직한 접근이 벼락치기를 언제나 이깁니다.
조금씩 자주. 짧고 규칙적인 연습 — 하루 10분의 집중 — 이 몰아치는 주말보다 더 많이 쌓입니다. 꾸준함이 조급함을 이깁니다.
요령보다 이해. 문제를 풀 때마다 왜 그 답이 맞는지 아이에게 설명하게 하세요. 이유를 말할 수 있으면, 그 실력은 처음 보는 문제에도 이어집니다.
문제를 두 번 읽기. 대부분의 실수는 놓친 한 단어에서 옵니다 — ‘아니다’, ‘오직’, ‘남은’, ‘각각’. 고르기 전에 꼼꼼히 읽도록 가르치세요.
영역을 섞기. Reading, Mathematical Reasoning, Thinking Skills를 오가며, 한 번에 한 가지 능력이 아니라 실제 시험처럼 연습하게 하세요.
말로 풀어보기. 보드게임, 퍼즐, 그리고 ‘어떻게 알았어?’ 같은 대화는 시험이 보상하는 바로 그 추론을 길러 줍니다 — 학습지 한 장 필요 없이.
사실에서 시작하기. 무료 평가는 각 영역에서 아이의 실제 수준을 보여 주어, 이미 할 수 있는 것이 아니라 정말 중요한 빈틈에 시간을 쓰게 합니다.
