Qualified ETH student organizations can request access to ETH staff software in IT Shop to be used for work related to the student organization (but not for academic studies). Send an email to firstname.lastname@example.org with information about your student organization and the person who will order software for the organization. Note that both the person ordering software and the persons using the software have to be enrolled ETH students.
What is required for your organization to qualify? Your student organization needs to have close ties with ETH Zurich and pursue a purpose that is solely academic and non-commercial in nature.
