OC Practice Tests & Past Papers: Free Resources

Practice tests are the most effective preparation tool for the OC placement test. Research consistently shows that students who complete timed mock exams perform better than those who only study content — because the test isn't just about knowledge, it's about applying that knowledge under pressure.

Here's what practice tests specifically develop:

• Time management — learning to pace 35 questions in 30 minutes
• Exam stamina — building the focus needed for a 90+ minute testing session
• Question familiarity — recognising common question types and knowing how to approach them
• Stress resilience — reducing anxiety by making the exam format feel routine
• Diagnostic insight — identifying which topics or question types need more work

A student who has completed 10–15 full practice tests under timed conditions will walk into the real exam feeling confident, not surprised.

The NSW Department of Education does not publicly release official OC test papers. Unlike the HSC, which has a full archive of past exams, OC test papers are classified and not distributed after the exam.

This means any resource claiming to offer "official OC past papers" is likely:

• Recreated from student recollections (which can be unreliable)
• Practice papers styled to look like official papers
• Outdated material from before the test format changed

That said, there are high-quality unofficial practice resources that closely mirror the real test format. The key is choosing materials that match the current test structure and difficulty level.

Not all practice tests are created equal. Here's how to evaluate whether a resource will actually help:

• Covers all three components — Thinking Skills, Reading, and Mathematics should all be included
• Timed format — practice without time limits doesn't build the pacing skills needed for the real test
• Appropriate difficulty — questions should be challenging but fair, matching Year 4/5 curriculum level
• Worked solutions — answers alone aren't enough; your child needs to understand why an answer is correct
• Multiple choice format — the OC test is entirely multiple choice, so practice should be too
• Updated content — ensure the resource reflects the current test format

Avoid resources that are overly difficult (designed to make students feel they need more tutoring) or overly easy (which gives false confidence). The best practice matches real test conditions as closely as possible.

Several free resources can supplement your child's OC preparation:

• SelectiveExams.com.au — free monthly mock exams covering Maths, Thinking Skills, and Reading with instant results and worked solutions
• Khan Academy — excellent for reinforcing maths fundamentals
• Reading Eggs / Epic! — builds reading comprehension and vocabulary
• Mathspace — interactive maths practice aligned to the NSW curriculum

For Thinking Skills specifically, look for resources that cover:

• Pattern recognition and sequences
• Spatial reasoning and mental rotation
• Logical deduction and syllogisms
• Analogies and classifications
• Number series and code puzzles

Thinking Skills is the hardest component to find quality free material for, which is why regular mock exams that include this section are especially valuable.

There's no magic number, but here's a sensible framework:

• Minimum: 5–8 full practice tests before the exam
• Ideal: 10–15 full practice tests spread over 3–6 months
• Maximum: One full test per week in the lead-up — more than this risks burnout

Quality matters more than quantity. After each practice test, spend time reviewing:

• Every incorrect answer — understand why your child got it wrong
• Questions that took too long — even if correct, slow questions signal gaps
• Patterns in errors — are mistakes clustered in one topic area?

The review session after a practice test is often more valuable than the test itself. Don't skip it.

A structured practice schedule prevents last-minute cramming and keeps preparation stress-free:

6 months before the test:

• One practice test per fortnight
• Focus on identifying weak areas
• Daily reading (20 minutes) and maths practice (15 minutes)

3 months before the test:

• One practice test per week
• Targeted revision on weak areas
• Increase Thinking Skills practice

Final month:

• One full test per week under strict exam conditions
• Review and consolidate — no new content
• Focus on confidence and mental preparation

Most importantly, keep the schedule sustainable. A child who is relaxed and well-rested will outperform a child who has been drilled for hours every night.

SelectiveExams provides free monthly mock exams that cover the exact same skill areas tested in the OC exam — Mathematics, Thinking Skills, and Reading Comprehension.

Each mock exam includes:

• Strict timed conditions — the timer cannot be paused, just like the real test
• Instant automated scoring — see results immediately after submission
• Worked solutions — every question has a detailed step-by-step explanation
• Performance analytics — time per question, accuracy by topic, and trend tracking
• Public leaderboard — see how your child ranks against thousands of other students

Our exams are designed for the selective school test, but the skills overlap almost entirely with the OC test. Students targeting OC placement will find these mock exams invaluable for building speed, accuracy, and exam confidence.
