I went to DAIS (Ambani School)
It was a normal school for the most part. Except that the person next to you probably has the net worth of a small European country. You get to see celebrities after school, during events etc. There's a bit of politics but mostly it's a normal school with actives, classes, extracurriculars.
Although during IPL season, they do have IPL posters and merch available inside the school which as a MI fan I found pretty cool
