In which order should I do questions?

After I finish a chapter how should I do questions to finally reach jee mains lvl? Obviously going straight to jee mains question is idiotic. For eg if I did sets yesterday and did all the ncert questions what's should I do next?(btw is sets combined with relations and functions for jee?). Like this for Chem and phy too. And is doing all the questions in ncert a must? I'm a 10thie btw( I did sets a week ago, has been procrastinating ever since(￣ー￣).
