Congratulations to all the new intake! I hope they will be as happy as DS was. He adored his time at Oxford, even during Covid.
Our highlights included attending a candlelit carol concert (DS was a choral scholar) the quad all lit up with fairy lights and the snow softly falling ; one (only one) formal hall parents' dinner in the final term. I think they suddenly realised they'd forgotten our cohorts' parent dinner because of all the lockdowns and squeezed us in before they all had finals! Then graduation day, which was a crazy, happy squash of photos in the Sheldonian and the Bodleian, and champagne in the quad at college.
I strongly agree with advice to buy the best mattress topper (and maybe pillows too) that you can find. College beds are very old school.
And earplugs! Those high, hard stone walls act like microphones to every sound, so even a couple of students chatting late at night can amplify, let alone partygoers at 3am rocking down Turl Street. Or college clocks chiming every hour of the night.
