@matigo Hmm, I don't really have too much of an opinion on expectations during my university years.
I was in the top 3 in my cohort for undergrad because only a handful of people actually cared about their grade — most just wanted to pass. So there were definitely no expectations imposed on me by classmates. For my master's, the cohort was so varied in age/background/culture that people seemed to avoid passing judgement or imposing expectations, especially as we didn't do much group work.
I was lucky to mostly have great teachers who cared as much as I did. (Good for me because I often pestered them about things.) The few times I suggested something wasn't my priority, though, they accepted it without question, so no expectations there.
