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.
3 difficulty levels
Start with Standard papers to build confidence and foundations. Progress to Challenge for multi-step reasoning. Then tackle Advanced papers for the toughest questions under real 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.

Question types you'll encounter
Our practice papers cover every question type in the mathematical reasoning section of selective entry and scholarship exams.
Word Problems
Multi-step problems set in everyday contexts — shopping, time, distance, and sharing.
Number Patterns
Identify rules governing numerical sequences and predict missing or future values.
Data & Graphs
Interpret information from picture graphs, bar graphs, and simple tables.
Geometry & Measurement
Solve problems involving shapes, area, perimeter, length, mass, and capacity.
Fractions & Decimals
Compare, order, and calculate with simple fractions and decimals in context.
Logical Reasoning
Use clues and constraints to work out unknown values through reasoning.
Preparation tips for mathematical reasoning
- 1
Read the question twice before calculating. Many mistakes come from solving the wrong problem.
- 2
Draw a picture or diagram — especially for word problems. A quick sketch can make the answer obvious.
- 3
Learn your times tables up to 12 × 12 so well that you don't need to think about them.
- 4
Check your answer by working backwards. If you calculated 7 × 8 = 56, check that 56 ÷ 8 = 7.
- 5
For pattern questions, write out the differences between each number — the rule often becomes clear.
- 6
Don't spend too long on one question. Circle it and come back at the end.
