# Group work in the exercises

Maybe a clarification on "group work" is needed -- it seems that in exercise 2, there were several groups submitting identical solutions, because students from one university (but from different groups) solved the exercise together. That is not exactly the idea of the group exercises… while we encourage collaboration among students, we would like to foster the collaboration **among students from different universities**, i.e., the members of one "Study Group" should solve the exercise together as a team, without "outsiders". In other words, you are supposed to collaborate within your own "Study Group" and deliver **one original solution per group**, i.e., you cannot share your solution with other groups. That also implies proper communication among **all** group members. Thank you for your cooperation! :-)
