I live in canada. and am currently in grade 11. i have one more year, then I am planning on attending Sheridan college for their practical nursing diploma. I want to become a RN (registered nurse).. but no sure of the process from becoming a practical nurse to RN. After becoming a practical nurse, how do I upgrade myself to become an RN? how many more years will it be? Will I have to go to a university? is it another accredited online nursing college for diploma or degree? what will be the salary difference? is their such thing as an upgrade for registered nursing diploma?
