@MrKlaw, good for your DS. Remains to be seen whether our DS heeds our advice and heads on down to the appointment-free vaccine centre today. Really hope he does!
I was only talking with an academic I know yesterday. I think the online lectures are definitely going to continue to be a thing going forward, not least because the students like being able to access them in their own time. Not sure if this is an 'across the board' view by universities though!
Hope your DS in enjoying the end of year activities? DS was off to do an escape room experience with his friends. Think he's done more in the past couple of weeks than he had previously done in 15 months!
