With the selective entry exam approaching, parents often ask: "Should my child sit a practice exam before the real test, or is it enough to just prepare topic by topic?" The answer is unambiguous - yes, your child should do at least one full-length practice exam before exam day, and ideally 2 to 3. Here is why, when and how to make mock tests count.

The Short Answer

A practice exam (also called a mock test) under timed, exam-like conditions is one of the most effective preparation tools available. It is the difference between knowing the content and being able to perform under pressure. Studying topics is like practising individual skills in sport. A mock test is like playing a full match before the finals.

Students who sit mock tests before the selective entry exam consistently report feeling calmer, managing their time better and making fewer careless errors on exam day. The format becomes familiar. The time pressure becomes manageable. The unknown becomes known.

7 Benefits of Doing a Practice Exam Before the SEHS Test

1. It reveals weak areas while there is still time to fix them

A mock test shows you exactly where your child loses marks - not in general terms like "needs to improve reading" but in specific, actionable terms like "ran out of time on the last 8 maths questions" or "scored well on reading but poorly on verbal reasoning." This precision allows you to direct preparation time to where it matters most in the remaining weeks.

2. It builds exam stamina

The selective entry exam is 2 hours and 40 minutes of concentrated mental effort across 3 sections with 2 breaks. That is a long time for a Year 7 or 8 student. Without practice at sustaining focus for that duration, students often perform well in the first section and poorly in the last. Mock tests build the mental stamina needed to maintain concentration through to the end.

3. It develops time management skills

Every section has a time limit. Section 1 is 60 minutes for maths and quantitative reasoning. Section 2 is 55 minutes for reading and verbal reasoning. Section 3 is 40 minutes for two writing tasks. Students who have never practised under these time limits often spend too long on difficult questions and run out of time for easier ones they could have answered.

A mock test teaches your child to pace themselves - to recognise when a question is taking too long, skip it and come back later.

4. It reduces exam day anxiety

Fear of the unknown is a major source of exam anxiety. When your child sits a mock test, the exam format stops being a mystery. They know what the test looks like, how the timer works, how it feels to switch between sections and how to handle the pressure. By exam day, the process feels familiar rather than frightening.

5. It identifies careless error patterns

Many students lose marks not because they do not know the answer but because they make avoidable mistakes under pressure - misreading a question, circling the wrong option, skipping a step in a calculation. Mock test reviews reveal these patterns so they can be addressed before the real exam.

6. It calibrates your expectations

Without a mock test, parents and students often have an unrealistic picture of where they stand. A mock provides an objective data point - not a prediction of the final result, but a realistic snapshot of current performance that helps set appropriate expectations.

7. It practises the entire exam experience

A good mock test simulates the full experience - sitting in a quiet room, reading instructions, managing a timer, dealing with nerves, switching between question types and taking breaks. Each repetition makes the real exam feel more like "just another practice session."

Before a full mock test, start with a diagnostic to identify strengths and weaknesses across all exam sections. The free SK Diagnostic takes about 60 minutes.

When to Do Your First Practice Exam

Timing matters. Do a mock test too early and your child has not built enough skills to perform meaningfully. Do it too late and there is no time to act on the results.

Recommended timeline:

Important: Do not schedule a full-length mock test in the final 7 days before the exam. A poor result that close to exam day can damage confidence and increase anxiety. The last week should be about light revision, rest and routine.

How Many Practice Exams Are Enough?

The sweet spot is 2 to 3 full-length mock tests spread across the final 8 weeks of preparation. Here is why:

Quality of review matters more than quantity of tests. One mock test thoroughly reviewed - every wrong answer analysed, every time management issue noted, every careless error pattern identified - is worth more than three mock tests with no review.

What Makes a Good Selective Entry Practice Exam

Not all practice exams are equal. A good mock test for selective entry should have:

The SK Mock Tests are designed to simulate real SEHS exam conditions with timed sections, realistic question types and section-by-section scoring. They provide the exam-like experience that builds genuine familiarity and confidence.

What to Do After the Practice Exam

The mock test itself is only half the value. The other half comes from how you review the results. Here is a structured approach:

Step 1: Wait before reviewing

Let your child rest after the mock test. Review the results together the next day when they are fresh, not immediately after when they are tired and possibly frustrated.

Step 2: Look at section scores first

Which section was strongest? Which was weakest? This tells you where to direct preparation time. If reading is at 80% but maths is at 55%, the next few weeks should weight maths heavily.

Step 3: Categorise every wrong answer

Wrong answers fall into three categories:

Step 4: Build a targeted plan

Based on the review, create a plan for the next 2 to 3 weeks that focuses specifically on the categories where marks were lost. This is far more effective than generic "do more practice."

Step 5: Re-test

After 2 to 3 weeks of targeted preparation, sit the second mock test. Compare the results to the first. Celebrate improvement in specific areas, even if the total score has not changed dramatically.

Common Parent Concerns About Mock Tests

"What if my child gets a low score and loses confidence?"

This is the most common concern. The answer is to frame the mock test correctly before your child sits it. It is a diagnostic tool, not a judgement. Tell your child: "This test helps us find what to work on. A low score in one area just means we know where to focus. That is good news, not bad news."

"Is one mock test enough or do we need to buy multiple?"

One is better than none, but 2 to 3 gives you the ability to track improvement over time. If budget is a concern, start with the free SK Diagnostic test as your baseline, then invest in 1 to 2 full mock tests closer to the exam.

"My child already does lots of practice questions. Why do they need a full mock test?"

Practice questions build knowledge. Mock tests build exam performance. They test different things. A child who has done hundreds of practice questions but never sat a full-length timed test may still struggle with time management, stamina and the stress of the real exam environment.

"What if my child does really well on the mock and then gets overconfident?"

A strong mock score is a positive signal but should not lead to complacency. Remind your child that the real exam will have different questions. Use the mock result to maintain motivation: "You scored well because you prepared. Keep that preparation going."

Diagnostic Test vs Mock Test - What Is the Difference?

Parents sometimes confuse these two tools. They serve different purposes:

Use the diagnostic first to guide your study plan. Use mock tests later to test performance under pressure and track improvement.

Frequently Asked Questions

Should my child do a practice exam before the selective entry test?
Yes. Practice exams are one of the most effective preparation tools available. They build familiarity with the exam format, improve time management, identify weak areas while there is still time to address them, and reduce anxiety by making exam day feel routine. At minimum, your child should complete 2 to 3 full-length mock tests before the real exam.
How many mock tests should my child do before the selective entry exam?
2 to 3 full-length mock tests is the recommended range. The first mock identifies baseline performance and weak areas. The second tests whether targeted preparation has improved those areas. A third confirms readiness. More than 5 is generally unnecessary and can lead to fatigue or score anxiety.
When is the best time to do a practice exam for selective entry?
The first mock test should be done 6 to 8 weeks before the exam. The second should be 3 to 4 weeks before. The final mock should be 10 to 14 days before exam day - close enough to feel relevant but with enough gap to avoid burnout. Do not schedule a full mock in the final 7 days.
