Levels
Each level asks for different text, not just more speed. Clear one twice and the next opens.
How you want to learn
Practice adapts to your fingers. The course counts down to the whole keyboard. Levels change the text itself.

How the ladder works
The levels are not a list of speeds. Each one changes what the text contains as well as how fast you have to type it: the commonest words first, then sentences, then punctuation, numbers, capitals and accents, then all of them over longer passages. Speed alone would make this a chart of your best day; widening what you can type is the part that transfers to real work. How many levels there are depends on the language, because a level is only offered where that language can really produce the text it names - Spanish has an accents level and English does not, since no English sentence carries one.
A level needs clearing twice, not once. One clear can be a lucky passage - a run with no awkward bigram in it, or a stretch where every word was one you type often. Two at the same standard is much harder to get by accident, and it is the same rule the exam-readiness pages use for the same reason.
The ladder never moves backwards. A level you have cleared stays cleared even if a later attempt goes badly, because taking something away for one bad run is a punishment rather than a measurement. It also advances one rung at a time, so an afternoon of easy levels cannot skip you past text you cannot yet type.
