The interactive CASE STUDIES allow the users to master, practice or test their knowledge about different aspects of copyright. The users will be guided to analyse real cases through the proposed methodology, and will get feedback and explanations to the answers they give, be they true or false. Finally, they will find possible variations to the case, which aim at making users understand the subtle differences in the situation that often lead to very different answers. At the end of each case study, the users will find a summary of the questions, of the corresponding answers, and of the most relevant concepts to remember. Ready? Go!
