How important would ncert exemplar be for medical in 11th?

I'm not really preparing for neet(being forced to but I really don't want to 🥀) or any such exams, rather I want to be able to study abroad.. my coaching does make us do neet prep tho, and along with the coaching module I also have pw books just for the questions.. so is it necessary for me to refer to exemplar or would it be fine to skip it?
