When i finished high school ,I went straight to work and never really bothered about college.I got a good job?

working as a preschool teacher.I loved kids so I continued teaching for almost 9 years now.Then I just decided to go to college to get a degree.I tried to go to the school where my younger sister currently studies.I know how they say nothing is too late :) but i just couldn't imagine myself with 16 year old kids around.I am 30 now but the thought of having to study for three years just freaks me out.A friend suggested ETEEAP course.Any suggestions? I think I could finish much faster with this..thanks
