Yeah, they gave use pagers on a 3rd year IM rotation (which I stupidly took as an elective). Big institution, busy service, was paged multiple times and always had to call the operator to connect me from house phones. That sucked. I forgot that it happened until literally just now.
Topic to look up and present for 5-10 min is great. Great way to learn, usually not super time consuming, actually useful info, and can do it with little downtime. I don't pimp a lot, because it never really helped me learn, but getting people to present is nice.
Similar experience, except for note writing, I've seen a lot of bad notes written by MD and DO students, but I expect them to be bad. The point of assigning them notes is to get practice and make them better.
Are you in the midwest or west coast? I had a different experience out east, but people tend to be nicer here.
