My son still naps after lunch. What time does class 1 finish at Gowtham Model School, Moosapet?

Our son finishes UKG this year and we've started looking at schools for class 1. Gowtham in Moosapet is one we're considering since it isn't far from us. He still sleeps for an hour after lunch most days. His preschool ends at 12.30, so it has never been an issue, but from what I gather most class 1 days run well into the afternoon. Anyone with a child in the early classes there: what time does the day end, and how did your child manage without the afternoon nap? ❤
