Java Edition Companion Map
The Companion Map is an interactive creative map designed to accompany the tutorials. It illustrates the examples, and gives you the opportunity to tinker with them, so you can learn by doing.
Some chapters may also have practice exercises included in the map, where you have to do things like fix or complete a redstone device, with an included answer key if you get stuck.
Unfortunately, the Companion Map is only available for Java Edition; there is no way to convert Java maps to Bedrock maps.
