How many years do you stay in school to become a Radiologic Technologist?

This is an associates degree program, so that's two years. You can't stop when you feel like it - you have to complete all the coursework required for the major and by the college.

It's offered at a lot of community colleges, so check there first. I don't know if you'd find this harder than nursing, but you can usually look up the courses required for each major on the community college website, and get some idea of what's required.

You can get a two year degree. Why not look on the web site of your community college. If they have this program, get a meeting with admissions and the head of the program
