Flux Chamber Trials: the licensing exam

Free, and you can take it as often as you like. There is no clock and nothing to lose: a wrong answer costs nothing.

Thirty questions. Say what a sign sounds like, find a sign by its sound, read four words and write two.

Get twenty-four right and you are certified as a Reader. A certificate has its own page, which shows your Earth number and nothing else about you.

Every picture of a sign has a description of its shape, so the exam can be taken without seeing it.
