Niece starts class 5 in June. How heavy are the evenings at Joy International, Bachupally?

We're in Bachupally, and Joy International School keeps coming up as the nearby option for my niece. Her parents and I share her schooling decisions, and as the one living closest, I've been asked to find out what I can. I'm a teacher myself, so I know every prospectus says 'balanced'. What I'd love is a parent's version. How much written homework comes home in class 4 or 5 on a regular weekday? Are there projects that need a lot of help at home? She is a big reader and I'd like her evenings to still have room for that. Any experience from current or past parents would be lovely ❤
