Leave for ca final exam

Dear Sir,

I want to know whether,is there any provision in 'The Chartered Accountants Act,1949' for leave to be granted to the articled assistant for preparation of his/her CA Final examination.

Further, please also tell whether is it mandatory to get CA Final Examination form attested by the principle under whom the very articled assistant is serving his articleship or attesting it by any other Chartered Accountant or any gazatted officer could serve the purpose.

Thanks in Advance

With Regards
