Dear Leonardo,
The idea is that the groups for the "Aulas Práticas" are the same as groups for the final project. If it is not possible for you to have the same groups, then make new groups for "Aulas Práticas" but then keep these same groups until the end of the semester.
On the other hand, I have got a list of groups for the final project already. You are free to make new groups if you are not part of any.
Best Regards,
Nestor Catano
