Pantjog, good luck to your DS and I'm sure he'll have done better in his exams than he believes. I also think that this year, the colleges will need to make a bit of allowance for the difficult times for all students.
Hobbema, DS1 hasn't swum in the Cam either and is unlikely to do so as he's heard various horror stories about sewage, Weil's disease (from rats) and the occasional corpse or two! However, as a family we all do wild water swimming whenever we can and my genes being those of a hardy northerner mixed with Irish potato famine stock, have served me very well! We used to enjoy swimming all year round in the north sea and in glacial Scottish lochs when I was growing up and I've brought up my sons to do the same. I'm sure those that have braved the Cam will all be fine however.
I hope all those lucky enough to be 'allowed' to visit their progeny have great trips. I wish mine would let me!
DS2 (O) has his first exam on Tuesday and his last one on 23rd June, the day before I'll need to pick him up, as we then go away on holiday (UK based thankfully). So they can't stay on at all, sadly and will miss anything organised for the following week.
DS1 (C) only has one exam (plus essays to submit for assessment) and that's across a 12 hour period next Saturday. I know I keep harping on about it but he STILL hasn't had a single essay marked all term for that exam. I just really find this weird. Why set essays if you're not going to mark them? How can students know how they're doing and how to improve if not given any proper feedback? He's totally fine with this though. It's just me who's bothered.
Sadly, he's still found no one to attend a college Formal with him whilst DS2 has now done 5 Formals at his college. DS2 has also played some inter-college hockey and joined cross-country training along with the rowing he already does. His college bar is provigna useful focal point for socialising too.
DS1's rather more solitary life continues and everyone is now very embroiled with exams. My sociable, musical, sporty son just hasn't had anything like the opportunities that his brother has had at Oxford. They'll both be home soon though.
It feels such a very short time that they've been away during their first university year and I've had virtually no time at all for any of my own plans at all. It'll be great to see them though and speak to them again after their weeks away.
