Hello aspirant,

hope you are doing absolutely great.

So with regard to your query, you haven't mentioned about the name of the school you are interested, so, I'm providing in general.  For the purpose of applying to 6th class admission generally you need to go to the school to which you are interested and write an exam conducted by the school for the admission purpose and pay the fee and join in the school. For the government school there is no such fee payable.

Hope it helps you,

Thank you.
