+## HPC resources for courses
+
+A [course project](../accounts/how-to-create-new-project.md#course) can host a
+maximum of 50 students at a time. Please note that course projects are subject
+to the same Slurm job priority policies as regular computing projects, meaning
+that course participants may need to queue for resources if the system is under
+heavy use.
+
+To ensure the availability of resources at the time of the course session(s)
+and thus avoid queuing, an _advance resource reservation_ may be requested for
+the course. In this case, please
+[contact CSC Service Desk](../support/contact.md) **at least 14 days beforehand**.
+
+The request should be motivated and include:
+
+1. the number of participants,
+2. the resources planned for the course,
+3. and a timetable showing the schedule of the course.
+
+Advance resource reservations for courses can be made for a maximum period of 5
+days in total and for a maximum of 9 hours per day. In special cases this may
+be increased to 10 days and 12 hours per day, but such a request will go
+through a more scrutinized approval process.
+
+The maximum amount and type of reservable resources depends on whether the
+request concerns Puhti or Mahti. Please
+[consult CSC Service Desk](../support/contact.md).
