At SPS we did $50 dues every month, which seems to be what most the classes pay here. However, we all got 180 back after we all graduated so total cost here was about 400-450 for the year of upt. That covered food/beer for the various parties(for students, IPs, and fam when they were invovled), patches, scarves, assignment night, and everything else flight related up to graduation. Our class took the view of paying more in dues to ensure everything would be covered and then getting a kick back on the left over funds once we finished.
