OC content outline and where to practise each area

The content areas below are copied from the official OC content outline published by NSW Department of Education, with the share of the exam each area carries. The right-hand column shows which of our practice sets covers it.

Worked examples: how to reason through OC questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: Bird is to nest as bee is to ___.

1. den
2. hive
3. burrow
4. web

Answer: B. hive

Explanation:

The pair shows an animal and the place it lives. A bird lives in a nest, so the matching home for a bee is a hive, which is option B.

A den is where animals such as foxes or bears shelter, so it does not fit a bee. A burrow is a hole in the ground dug by animals such as rabbits, which is not where bees live. A web is a trap a spider spins to catch food, not a home built for bees.

Rule to remember: put the relationship into a short sentence first, such as 'a bird lives in a nest', then test each option in the same sentence. Only the option that keeps the same relationship fits.

Example 2

Question: What is the missing number: 7, ___, 21, 28, 35?

1. 10
2. 12
3. 14
4. 16

Answer: C. 14

Explanation:

The terms 21, 28 and 35 each go up by 7, so this is the 7 times table. The missing term comes before 21, so it is 21 minus 7, which is 14. You can also check it from the start: 7 × 2 = 14, option C.

Options 10, 12 and 16 are wrong because each leaves uneven gaps on either side of it, so the sequence would no longer move in equal steps. Option 16 also sits above 14 even though the numbers are rising towards 21 from 7, which shows how a near miss can still break the pattern.

Rule to remember: find the constant step between the terms you can see, then check that it holds across the gap.

Example 3

Question: Which of the following is NOT necessarily a property of a parallelogram?

1. Opposite sides are equal
2. Opposite angles are equal
3. All angles are right angles
4. Diagonals bisect each other

Answer: C. All angles are right angles

Explanation:

The question asks which property is NOT necessarily true, so you are looking for the statement that fails for some parallelograms. That is option C, all angles are right angles. A parallelogram can be leaning over, with angles that are not right angles. Only special cases, rectangles and squares, always have them.

Option A is wrong because opposite sides are always equal in a parallelogram. Option B is wrong because opposite angles are always equal. Option D is wrong because the diagonals always cut each other in half.

Rule to remember: when a question uses NOT, test each option against the general shape and choose the property that only some members of the family have.

How to use these practice tests

Start with the official material from the NSW Department of Education. Read what each area of the test asks and try the official practice tests on a computer, because the real test is taken on screen.

Then work through our sets by area. For maths, use OC Mathematical Reasoning and OC Numerical Problem Solving. For reading, use OC Reading Comprehension and Vocabulary. For thinking skills, use OC Logical Thinking and Problem Solving and OC Spatial and Visual Reasoning.

• Do short sets often rather than long sets rarely.
• After each set, read the explanation for every question you missed and write down the rule behind it.
• Return to missed question types a few days later to see whether the rule has stuck.
• Practise with a timer for each area, using the official time limits, so pacing feels familiar.

Use OC Test-Taking Strategies in the last stretch to practise skipping, returning and checking. Our questions are written by us and are not real exam questions, so treat them as practice for the skills, not a preview of the paper.
