Sector 57's family safety is good but schools are tricky

Spent the whole Sunday checking out options in Sector 57. Really liked the general vibe for my family; my wife's priority is safety for the children, and it seemed pretty good there. We need at least a 3BHK. But I'm honestly not sure about the schools nearby. Are the good ones too far or super hard to get into for kids' admission? Also, how's the actual day-to-day life there? Is there a decent community feel, or is everyone just isolated? Any hidden issues for families should know?
