Nursery forms at Little Buds Grammar High School, Nallakunta. Walk-in, or appointment?

asking for one of the nurses at our clinic. she lives near Nallakunta and doesn't use these apps. her son would go into nursery in June 2027. when do forms usually come out there, and is it a walk-in enquiry or do you need an appointment? also whether the nursery section keeps its own timings. ours is long past this stage, i've forgotten how any of it works
