Checking Hari Hara Grammar High School in Nagole for my niece, who joins nursery when they move next June

They are relocating from Warangal and their daughter will be starting nursery. Hari Hara Grammar High School is a short walk from the flat they're looking at, so it is the first place I'm checking for them. Two things. Do the youngest children finish earlier than the rest of the school, and do they eat lunch there or go home before it? I'll go to the office myself next week, but any idea beforehand helps.
