SSS High School in BN Reddy Nagar as a walkable backup for class 4. What is the day like?

Our daughter's class 3 at her ICSE school wraps up later this month. We are on a waiting list elsewhere for class 4, and rather than scramble in June I would like a backup we are comfortable with. SSS High School is within walking distance of us, which counts for a lot. For parents with children in the junior section there: when does the day start and finish, what is the homework load like, and if they came from another board, how was the switch? I would rather know these things before we go in for a conversation.
