The way to the Citizenship

There are some steps have to do before going to the Citizenship test .
I have stayed at Canada for three years about four years .I think about 1095 days before going to the test
I have to sure that my English is good my age less than 54 years and I have to study a lot of information about the Canadian history and the Rights of Canada .before going to the Canadian citizenship test I make sure that is no crime about me .
Thank you .
