Does Geetanjali IIT Olympiad School in Marredpally keep its nursery classes on the main campus?

Saw the admission banner on the way back from exam duty in Secunderabad and it stuck with me. We're in Financial District, so this only becomes real if we go ahead with a move we keep discussing and never deciding. Our son is 3 and would need LKG next June. Our daughter is settled at her school and would stay put. For the younger one, two practical questions: are the nursery and LKG children on the same campus as the main school or in a separate building, and do the little ones follow the CBSE side or the State Board side, since the school lists both? Any detail from current parents helps.
