Hello @luchoej17,

Welcome to the community!

You can use the arrows at the bottom left corner of the screen to move between lessons. The arrows are next to the name of the unit you are in. You should see a text that says “Go to the previous unit” or “Go to the next unit” when you hover over the arrows. Click on the arrows with your mouse to move between units.

Here is an image of the area at bottom left corner of the screen:

Hope this helps,

Roberto
