@Jux I'm a External examiner at Exeter and I've just been consulted by the department I external for on the university plans for ensuring that current students' difficulties in a global pandemic don't have an untoward impact on their degrees overall.
It's complex so unlikely your DD understands - I had it carefully explained by the Exams tutor - they're doing a cohort check (they call it something else which I forget) - so they're checking marks for modules and year groups against several previous years (most universities keep this sort of data for 5 years), to ensure that this year's median and mean marks, and standard deviations in cohorts are not out of whack from those of previous years.
We've wrestled with this at my university - we can't do a 'No Detriment' policy as there is no benchmark mark for any student - they're doing all their work this year under national conditions of a pandemic. I think I'm going to pass on the Exeter plan to my own departmental Exams officer as a model & see what we're doing.
As for your other comments here & in another thread - you're tending to behave a bit like some of my undergrads - projecting your anxiety, frustration etc on the university. We're in a global pandemic - what do you expect universities to do? keep going on as normal?
If your DD has a registered disability, or is in some way registered with her university as needing extra support, or CEV (my place is trying hard to get students to let them know about this) then she should be able to get extra support for using the Library. My place offers a sort of Click & Collect - you ordered up books which weren't available digitally, and then you could collect them, in a wrapped parcel, from an outdoors collection point, masked up, with the university person in mask & wearing gloves.
If she's CEV, has she told her Department this, or her university? Again, my place has a reporting mechanism, and we regularly email students to check in. But if they don't tell s, and they're not already registered as having a disability/needing support (eg extra exam time etc), then we don't know if they don't tell us.
