When does SR Digi School in Nagole start admissions for the early classes?

My brother's family is moving to Nagole next summer with a 4 year old, and SR Digi School is near the lanes they're looking at. Since I'm in the area, he has asked me to find out what I can. I teach maths, but at a CBSE school and at the senior end, so I know very little about state board LKG and UKG. Two things he'd like to hear from parents there: roughly when the admission process for next year begins, and whether the early classes do a lot of written work or keep it mostly activity-based. First-hand experience would help.
