01 / Get familiar
What you’ll practise.
This practice asks you to find and select groups containing exactly four dots, while leaving groups of three or five unselected. Working across a table calls on sustained attention, pattern recognition and careful scanning.
Choose between one and five tables for a session. Each table lasts two minutes, and a new table follows automatically when the time is up.

02 / The format
How the practice works.
Find 4-Dot Groups
Scan each row and click groups containing exactly 4 dots
Avoid Others
Skip groups with 3 or 5 dots—accuracy is more important than speed
Work Quickly
Each table lasts two minutes. Keep working steadily; the next table follows automatically when time is up.
03 / Your approach
A few things to try.
Scan Systematically
Work row by row, left to right. Never skip around or you'll miss targets.
Maintain Pace
Find your rhythm early. Going too fast causes errors, going too slow means incomplete sections.
Focus on Targets
Memorise the target dot pattern before starting each section.
Accuracy Over Speed
Aim for accurate selections while keeping a steady pace. Compare correct, incorrect and missed targets in your results.

Common questions.
What is the Group Bourdon test?
The Group Bourdon test is a concentration and attention assessment used in UK train driver recruitment. You must find and mark specific dot patterns within complex grids under strict time limits.
How long is the Group Bourdon test?
Each practice table lasts two minutes. Choose one to five tables before you start; the next table loads automatically. Your assessment invitation and official instructions define the format of any assessment you are due to sit.
What is a passing score?
Use the practice results to compare your accuracy, incorrect selections and missed targets across sessions. These practice scores are not an official operator pass mark.
Can I practice as much as I need?
Yes! Train Driver Pro offers unlimited Group Bourdon test practice, so you can practice as many times as you need to build your confidence.
Are there time limits?
Yes. Each practice table has a continuous two-minute timer. Choose your table count before starting and give yourself enough time to complete that session.
What equipment do I need?
A computer or tablet with mouse/touchpad works best. The test requires clicking on dot groups, so precise input is helpful. A stable internet connection ensures your progress saves correctly.
Can I practise for free?
Core practice is free and can be used without an account. Sign in if you want completed results saved to your account. The optional additional practice pack is a separate purchase.
