ps:
some WE in a clinical environment or a care home, helps get a place at med school
Days & weeks more beyond that, doesn't default make it easier to get a place at medical school.
WE in exotic foreign place for 2 weeks doesn't get a place, either.
Fantastic WE, like shadowing your mum the hospital consultant and assisting in surgery doesn't help you get a place
The reason lots of WE doesn't impress is because rich kids are only ones who tend to have a chance of those over-&-beyond WE placements. The med schools do not want to make it harder for kids from less resourced backgrounds to get into medical school, and make it easier for the rich kids.
2-3 days of WE in a clinical environment is what nearly everyone had that I interviewed last year.
Just make the most of it, whatever the opportunities are. Think about what you can learn while there about the practice of medicine.
Helping at .... cadets, sports teams for younger kids, activities for disabled kids, serving tea & biscuits in care homes, painting nails for old gals in care homes, scouts, guides, St. John's Ambul, are other ways to get some relevant experiences. SJA is a really good one, actually. Can actually acquire real skills.
