How our practice tests help

EduSpark goes beyond basic practice papers. These features are designed to make every practice session count.

Per-question time tracking

See exactly how long your child spends on each question. Spot where they lose time — rushing through easy questions or getting stuck on hard ones — and adjust their pacing strategy before exam day.

Automatic weakness tagging

EduSpark identifies specific topic areas where your child loses marks. Instead of re-doing entire papers, focus revision on the exact skills that need work — a smarter way to improve.

2 difficulty levels

Start with Standard papers to build confidence and foundations, then move on to Challenge papers for multi-step reasoning under time pressure.

Unlimited retakes

Re-sit any paper as many times as needed. Track how scores improve across attempts to build confidence and measure real progress over time.

Getting started is easy

Five simple steps from sign-up to exam-ready confidence.

Explanations for every question

Question types you'll encounter

Our practice papers cover every question type in the thinking skills section of selective entry and scholarship exams.

Strengthen or Weaken

Read a short argument and choose the statement that makes it stronger or weaker.

Whose Reasoning Is Correct?

Two characters draw conclusions from the same facts. Decide which of them (if either) is right.

Identify the Mistake

Someone reaches a conclusion that does not follow. Pick the reason their thinking is wrong.

Must Be True and Ordering

Use clues about people, places or positions to work out what must be true or who is where.

Numerical Problem Solving

Timetables, calendars, comparing lists and working backwards from an answer.

Spatial Reasoning

Nets, folding, shapes and plans: picture how pieces fit or what something looks like from another view.

Preparation tips for thinking skills

1
Every answer comes from the information given. Do not bring in outside knowledge.
2
For argument questions, first say the conclusion in your own words, then test each option against it.
3
For "whose reasoning is correct" questions, check each character separately before choosing.
4
Draw a quick table or line for ordering puzzles and fill it in clue by clue.
5
For spatial questions, sketch the net or shape on scrap paper and label the faces.
6
If a question is taking more than a minute, make your best guess and come back to it later.
