I see a comment it takes a year to complete the WOCN. When you register for the course, it says 90 days to complete. Does that mean each course, W is 90 days, C, is 90 days, O, is 90 days, etc.?? That equals one year. So, my questions is how long does it take to finish the C and O classes? Would that be 6 months??? What if you take them together? Is that 3 months total? Sorry, I am just confused.....
