I'm a senior studying in an Indian residential school. I'm thinking of applying ED to CAS. I've changed 11 schools mainly because of my dad's job so I was thinking of writing about how that has made me who I am today and how even though this meant not being able to settle in a place for too long, I wouldn't change a thing about it.
I also have a blog, http://devaanjanagoel.blogspot.in/
This might give you an idea about how I write.
