Im in year 13 and for my mandatory placement I did it at my old primary school. it links well because i applied for childrens nursing! I know others who have done it in nurserys, care home, pharmacies, charity shops and even hospitals (which is actually quite hard to get) If you cant find work experience in a clinical setting, then dont worry. As long as the work experience will be able to let you transfer your team work and communication skills (+ Care) then thats honestly fine!
