oneteen, on mumps my son caught it just after the Easter holidays as did his friend (they came here to stay for 3 weeks for a bit of peace and rest). I was a bit cross. My children have had all the vaccinations going including MMR which means he only had 1 in 9 chance of catching mumps. yet he stil caught it. I am pretty sure the only reason mumps is so much around is because some parents chose not to give their children the vaccination.
His twin brother (they are both at Bristol) who had also had the MMR did not catch it (given the odds are only 1 in 9 if you have had the vaccination and I think zero if you have had mumps itself that is not surprising).
I have their vaccinations card here and I did copy that as his Bristol GP did a blood test and wanted confirmation of what vaccinations he had had; so parents might want to look out their child's vaccination list/cards at home in case new students are asked to produce them.
ui second the ID point. Mine passed their driiving tests at 17 but either way having a provisional or full licence and indeed for letting a house a passport is often needed or at least asked for can be a good idea. My twins had to find and book their year 2 accommodation before end of term 1 in year 1 by the way in Bristol and I remember posting both of them their passports by special delivery as teh letting agents apparently insisted on having them. They now keep their passports at university (and have not lost them so far).
