Ive registered for this - but cant find the free bit - other than their challenge to get you hooked in the first place - or am I missing something????
Since you are already registered once you log in, in the middle of the screen will show which languages you are learning, which ones you speak and then on thr right side you can pick which language you want to study (learning) and then you click on the start course. In thre next screen you click on learn to start your lesson.
Hope this helps! Let me know if you have more questions
