| Name | Stage | About every | What it asks |
|---|---|---|---|
| 56s | 3, basic | 56 days | Major places, around the Blue Book runs |

Moving through them
You need 12 points to leave each stage: 6 for an A, 4 for a B, 3 for a C. Each stage also has a time limit: three years for 56s, two for 28s and one for 21s.
The names are the candidates' own. TfL's documents call them Stages 3, 4 and 5, and its 2022 booklet basic, intermediate and advanced.
