Juliette,
I haven't used xtmixed much myself, but according to these threats it
might be possible to model four levels:

After finishing the first module, the participants are again randomly assigned to groups (n=32). As such I've got four levels in my data structure with "crossed"data among the students/group levels: 1) Repeated measures, 2) Modules, 3) Students, 4) Groups.
