@coffeegirl73 I'm sorry if this message comes too late but I'll answer since it might be helpful to others. My advice to those looking specifically for medical work experience opportunities is to start looking early, ideally year 11 if possible. We have no connections in healthcare, so it was a lot of research... which I helped her with. Also, DD's comprehensive state school offered very limited support for med school students, and very late in the process!
My DD did the virtual ones (BSMS, Observe GP) the summer before starting year 12. After that, she applied for volunteering gigs and medical work placements at one of our local NHS trusts. There aren't too many opportunities, especially for 16-year olds (DD is August-born). And most are restricted by post code. One of DD's friends also tried at local GPs but with no success.
DD was interviewed by our local NHS trust and was offered a weekly volunteering slot in a local outpatient clinic, but the whole process took over 6 months due to interviewing, background checks, induction days, and NHS backlog in processing applications (!) They require a min 6-month commitment but DD will continue volunteering pretty much until end of year 13 as this also counts towards her Gold DofE requirements (minimum 1 year volunteering).
Then she found an opportunity to do a 1-week medical work experience placement at another local NHS trust. This had minimum GCSE grade requirements and it was super helpful as she closely shadowed specialty doctors for a full week.
She also did a 1-week residential trip at Dorset hospital - this was organized by Hampshire council. For this one we had to pay about £800 (accommodation, meals, transport), but as my DD is doing Gold DofE, it also counts towards her residential Gold DofE requirement.
And in year 12 from Feb-July she took part in a weekly webinar series organized by KCL, which was incredibly helpful as they covered lots of medical topics and even UCAT and admission prep. If your DC is a state school student from a comprehensive / non-selective school, there are no contextual requirements. KCL organizes this annually.
Finally, she was selected to take part in Eton's course "Biology for Medicine" (see ESUPC) but this is for state schools pupils that are within commuting distance of Eton. It has minimum grade requirements (min 7) and teachers must recommend you. This was the only in-person summer school we found that didn't have contextual requirements.
