Every page here reads three ways, from plain English to full jargon. Here is how to set the dial, what a lesson looks like, and how to take the free stuff.Every lesson is one page rendered at three reading levels, and the dial in the top bar picks one. Here is what each stop is for, how a lesson is built, and how to take the free files.Site mechanics: data-level on , all three renderings in the DOM, CSS hides the rest. Lesson anatomy, the component set, and how giveaways are wired.

Try the dial: three steps from plain to jargonTry the dial: three reading levels on one pageThe reading-level gradient: how one page renders at three levelsDoneDonedone
The switch at the top is not on or off. It has three stops. Drag it and watch this page change its words and its look, one notch at a time.Three reading levels on one page. Glossary terms re-word themselves at every stop, and blocks that only make sense at some stops appear and disappear. This page shows every trick the site uses.Three reading levels on one HTML page: level objects (l1/l2/l3) in frontmatter, Term for vocabulary, Level ranges for gated blocks, Swap for inline phrases. This lesson exists to show the mechanism.

How the course is organisedHow the course is organised: sections, exams and badgesCourse structure: five sections, one exam each, badges and the certificateDoneDonedone
The course comes in five sections. Each one ends with a short exam. Pass it and you get a badge; pass all five and you get the certificate. Here is what is in each section and how the exams work.Five sections, each closed by one exam you take at your own reading level. A pass earns the section's badge; passing all five earns the course certificate, printed at the level you passed at.Modules grouped into five sections; one exam per section rendered at three levels and graded server-side; section badges; a course certificate issued at min(best level per section).

The interactive parts, one of eachThe interactive parts: one of each, and what they are forThe exercise kit: choice, order, match, explore, write, and the playgroundDoneDonedone
Lessons have small things to tap, sort and write. This page has one of each, about the course itself, so you know how they work before they count.Five kinds of exercise and one live playground, each shown once on this page with a real example, plus what XP, the streak and the page's memory do.One instance of each exercise type (choice, order, match, explore, AI-graded write) and a decision-model playground, with the XP, streak and localStorage behaviour behind them.
