You have not mentioned your nationality. However guessing that you are Indian you have a big choice of schools for KG/Primary education. There are more than 6 schools. I would personnally reccomend Birla or DPS. There are others Like MES,IDEAL and DMIS.

Regarding universities there are many and admissions are not tough. Depends on your High school marke and how much you are willing to shell out.
