What every OC class at Elite works on.

Start with the entry assessment
  • Mathematical Reasoning and Thinking Skills taught with equal weight, because each is worth a third of the mark

  • Thinking skills from first principles, starting in Year 3

  • Familiarity through mock tests, so the real paper is not the first timed paper

Mathematical Reasoning

From Elite's Week 1 paper

Two whole numbers add to 22. The greatest value that their product could be is _____.

Show the worked solution

For a fixed total the product is largest when the two numbers are equal, so 11 times 11 gives 121. The distractor 484 is 22 times 22, which multiplies the total by itself instead of splitting it in two. 120 is 10 times 12: close, but numbers that differ give a smaller product than equal ones.

This tests Number properties. The answer is C.

From Elite's own Week 1 Mathematical Reasoning paper, with a fifth option added because the real test gives five. The clock runs at the real test's pace: 35 questions in 40 minutes is about 69 seconds a question.

Thinking Skills

From Elite's Rex's sample questions

At lunchtime, students who forget their hat stay under the veranda. Students on a lunchtime detention also stay under the veranda. Mo: "Ari was under the veranda at lunch, so Ari must have forgotten his hat." Lia: "Bella had her hat on today, so Bella was not under the veranda."

If the information above is true, whose reasoning is correct?

Show the worked solution
  1. Understand the question. Conditional Statement. Two sufficient conditions that lead to the same place.
  2. Use the strategy. Write both rules. Rule 1: no hat, so veranda. Rule 2: detention, so veranda. Each has a contrapositive: not under the veranda, so had a hat; not under the veranda, so no detention. Now notice that two different things send a student to the veranda. So seeing someone there tells you one of the two happened, not which. And knowing one reason is missing does not clear the other reason.
  3. Apply the strategy. Look at Mo. Ari was under the veranda, so he forgot his hat. That is "B, so A" on Rule 1, the converse. Ari might have been on detention with his hat on. Mo is wrong. Now Lia. Bella had her hat, so she was not under the veranda. That is "not A, so not B" on Rule 1, the inverse. Rule 1 only covers hatless students. Rule 2 could still put Bella there if she was on detention. Lia is wrong.
  4. Confirm the answer. D. When two rules lead to the same place, the converse of one rule ignores the other rule, and so does the inverse.

This tests Logic reasoning: conditional statements. The answer is D.

Chosen by Rex for the website, 9 November 2026, with his own answer and four-step explanation. The clock runs at the real test's pace: 40 questions in 40 minutes is about 60 seconds a question.
