my country has no work exp!!!!!!

Hi guys!
I need help. Basically my parents have decided to relocate to the middle east as I’m entering y12. I will be doing iALs in a british school (maths, fm, phy, art). My one problem is that in this country, there is NO work experience. like it’s literally illegal to work before 18. I want to apply for architecture in a Russell group at least, but i feel like there’s so little for me to possibly do outside my portfolio and grades, so i don’t know how ill get in. Does anyone know how to find any online work experience, scholarship prizes etc. I looked online but nothing seems to be aimed at architecture. should i do subject-specific work instead? like maths/physics stuff? i mean my friend told me in architecture they don’t care abt that so im torn!!!!!!
