Hi, have namechanged for this to save complications ...
DS will be applying for an organ scholarship. Subject however still to be determined ... Maths, physics, music are all still contenders (and computer science and engineering deserve(d) a proper look).
Cambridge have an online organ open day tomorrow which we're looking forward to, don't yet know what Oxford are doing (but am assuming that they are holding off confirming a date in the hope of having it face to face again?).
I've been trying since last summer to help DS engage with thinking about university but it's been hard. He's good at too many things plus perhaps a little immature in some respects (though in others quite the opposite). Also, he's in a high-achieving group at school, so has for example expressed his concern that he isn't good enough to aspire to maths at Cambridge. My impression is that he definitely has the ability.
It's hard enough that Oxbridge deadlines are earlier than others. Organ scholarship applications are due on Sep 1st ... Then they audition them and get their results to them before the UCAS deadline so they know what to put on their form. Currently I still know more about the process than DS knows, hopefully that will start to change soon!
Regarding extra-curriculars, I agree that it's only things directly relevant to the subject they apply for that form a focus, from all I've understood. (DD tried for English at Oxford, currently on a gap year. The college would have had her for their choir very happily but she didn't make the academic cut. Alternative destination looking very positive for her)
If DS settles on maths he may have to sort out some compromises at school. There are both a coding club (that he used to be in) and a STEP preparation session that he can't currently attend due to clashes with music activities ...
