I am new here ^^ I am a bit confused how to use it, where to find the lessons, can anyone help me ?
Step 1: See that too bar thingy at the top of your page. It should say: Home, Activity, Discussion, and Immersion. Click Home.
Step 2: Duo should appear and ask if you want to stary with Basics 1 or take a test to move forward. You can choose which one.
Once you have done what JustPlainMusic says, if you decide not to test out, click on the button on the right side under the icon. That will start your first lesson. There are no lectures, explanations, etc presented before the sentences start, but you can hover over words (and sometimes phrases) for their meaning.
