Group Bourdon practice

18 August 2026 · 5 min read

Group Bourdon practice is timed pages of dot clusters. Each sheet has a target count. You mark every matching group and leave the near-misses. The rule is simple. The page is not.

If you have already read what the test is, the remaining work is building a scan you can hold. One heroic attempt at the kitchen table does not do that.

What to practise, exactly

  • Timed sheets, not untimed puzzles. The clock is part of the task.
  • Several pages in a sitting, not one. Assessment day is one more paper after something dull.
  • The target changing between sheets. Habit from the last page is how people mark fours when they wanted fives.
  • A scan you can name: left to right, or whatever the live instructions say, without skipping rows.

Paper and screen both exist. Follow the version you will sit if you know it. If you don't, practise the rule, not a motor habit that only works with your kitchen pen.

Watch two numbers

Coverage and errors. If you only watch how much you marked, you will rush. If you only watch how clean the page is, you will finish a third of it. Operators care about both.

A useful session is slightly worse than your best morning. Practise when you are a bit tired. That's the half of the day that catches people who only ever sit a fresh puzzle.

What not to do

  • Cram the night before. This is a habit, not a fact you can memorise.
  • Chase a score from a website as if it were a pass mark. It isn't.
  • Speed up until you are guessing. Panic with a pen still counts as errors.

No practice site is the official paper. Use it to learn a sustainable scan. On the day, read the live instructions and start at the pace you practised, not a new heroic one.

Independent practice notes. This is not an official test, and we are not affiliated with train operators or RSSB.
