JMSS_hopefully uhm you don’t need anything fancy, they ask for leadership in secondary, extracurriculars, scientific interest beyond the skl curriculum and 5 max pics of any achievements u hv. For extracurriculars, I have bball, singing and flute. Leadership was house cap and section leader in band. Science stuff was diff magazines I read, stuff from comps like big science etc and js talking abt what in science interests me. My 5 were top 10 in maths Olympiad, distinction in big science, bball award, viscomm award from skl and a singing cert. I also had an achievements section which was achievements from yr 6 to this yr. Hope this helps!
