grandson may move to ravindra bharathi school in dilsukhnagar. how much homework in the early classes?

my grandson is 5. his parents live on the dilsukhnagar side and are looking at ravindra bharathi school for next year. i do afternoons with him three days a week, mostly homework and snacks. i can sit with him and keep him at it. i can't always check every answer, the methods have changed since my time. would like to know from parents there how much homework comes home in the early classes, and whether teachers expect it corrected at home or just done
