If i achieve a bachelors in exercise science, will it require less credits to add a physical therapy degree?

PT is a graduate degree-3 years beyond a BS degree. Your undergrad degree can be anything. You are required to take 1 year of gen bio, gen chem, A and P, gen physics, math upto calc, stats and psy. Exercise science is a great major but it will not get you through PT school any faster. FYI-PT is a DPT now (not a masters)
