O levels in kg 1 and kg2

hi all,

could you please throw some light on this idea of mine??
i was wondering whether it will be good for the kids to be put in O levels in thier kg1 n kg2 and then later shift them to a cbse school in grade 1??? apart from hindi, are the other subjects in par at both cbse and O levels..?? n hindi..will it very difficult for them cope up in 1st grade??am asking all this because the kids will need to get through the written test for grade 1 correct??

this thought came across my mind when i was thinking about their language, extra curricular activities and personality development.sorry for being silly...but could someone just give me their opinions??

 

any opinions??
