a BS in Respiratory Care/Cardiopulmonary Science is 2yrs pre-reqs then 2yrs of upper-division, which is the clinical portion of the program. my degree plan is 147hrs for a 4yr degree. its taken me 5yrs only because i didnt know what i wanted to do and actually didnt go to school 1 semester.
most medical bachelors degrees require 2yrs of pre-reqs, but then its only 2 yrs upper-division, ie nursing, perfusion, etc. i dont know which 6yr programs you're thinking about. can you please name them?
