If you are a Premium learner, then you can simply switch from one language to the other.
Click on the flag in the top left corner, and select the language you want to learn.
If you don't have a Premium subscription, then you can only learn one language.
If you have just registered and selected a language by mistake, let us know here: https://www.busuu.com/en/contact within the first week of registering, and we can amend that for you.
Once you have started learning a language however, we won't be able to change it for you.
If you want to learn more than one language, why not upgrade to our Premium membership!
