"Needmoreslep you're a master of misinterpretation! I didn't imply anything about boring drudges that's pure fiction. You do have form for this though."
Honestly all I have tried to do on these threads is share experience. I can accept I may be over sensitive, but advice on MN from a couple of regular posters, can come across as everything is easy as long as your DC are very very clever . You did, to be fair, suggest that your DS had been wise to skip volunteering to practice the art of relaxation., which suggested others were unwise.
Medical school applications in this household were not easy. DD did not get an offer till late March. A couple of her good friends did not get any offers. Skiiltan's link was interesting. A specific problem for DD was UKCAT. She is dyslexic with slow processing speeds so this sort of timed aptitude test (Grammar 11+, CAT etc) tends to be a nightmare. So it was a case of taking BMAT or looking at those Universities that give weight to the PS. She preferred doing stuff, to revising for BMAT.
Curiously, her school would have strongly advised against Stranger's DS' approach of not taking UKCAT. BMAT, especially if taken after the UCAS deadline, is a risk. But it worked for him. Whilst DD, with bags of volunteering/EC/shadowing/school leadership, got the course she wanted and one that suits her. The key thing to emphasise is that these are individual experiences. DDs volunteering would not have got her into Oxford (a good BMAT is all important - and though her school used to try to preach the need to have a wider offer, Oxbridge did not seem to be too bothered whether it was offered or not, seemingly preferring super-bright applicants with super grades). But she did not apply. Oxford seems to have suited Stranger's DS, and he might not have enjoyed a much more hands on, group working type of approach.
So to repeat the advice to OP. Different courses, different selection methods. It is worth considering carefully where your strengths and interests lie. Volunteering is one way of exploring this.
Wonky, interesting about the F1s dropping out. That accords with my Oxbridge friend suggesting that virtually none of her close peers had stuck with medicine. I wonder if Oxbridge gives you more City type options. I suspect that DDs course is structured in a way that you would pretty soon realise if medicine were not for you, so perhaps F1 and F2 wont be such a problem, and indeed perhaps that is why the (new) course is set up that way. DD likes it that way, though early struggles with the shift allocation system means she has early (useful?) experience of coping with NHS bureaucracy. .
