How is the best (safest&fastest) way to get the Canada's Permanent Residence?

I have tried to browse on the internet about Canada's Permanent Residence. and i tried a free esment test at one of the website which provides the immigration service to Canada with a lawyer consultation. It is said that my qualifications are qualified enough for applying the Canada's PR. but i'm still looking for some infos to get the fastest but safest way to guarantee that my application will be accepted. Any reccomendations from any of you who know about this?
