Most gymnasia offer social and academic clubs. Most traditional among these (sports excepted) are drama, journalism (i. e. producing a Schülerzeitung) and choir. However, chess, photography, debating, improv, environmentalism, additional math, experimental physics, IT classes, etc. can also be found.
Some gymnasia require students to participate in at least one club (of the student's choosing), but in most cases, participation is voluntary.
