When a learner gets the opportunity to send an exercise for correction (at the end of a lesson or from the Social section), it can either be sent to the community, or to specific friends they have in their list of friends.
As a learner, you can send your exercise, and it will be corrected by one or multiple learners who speak the language at native or advanced level. You will also receive exercises to correct for other learners, and you can select exercises to correct directly from the Social section.
This is the amazing advantage of learning with Busuu!
Native and advanced speakers help each other practise and progress!
