How late do primary children get home from Global Edgeschool in Madhapur, and with how much homework?

We are considering Global Edgeschool for our elder son, who will be in class 3 next year, and possibly the younger one for LKG. The website and the brochure describe the programme well. What I can't get from them is the ordinary part. Roughly what time do primary children get home, how much homework comes back on a typical day, and how often are parents expected on campus for events or meetings? If your child is in the junior classes, a plain description of a regular Tuesday would help more than anything about annual day.
