As you have not provided the particular college name from where you want to pursue this course so below I am providing the generic eligibility criteria -

Candidates who have completed 10+2 with an aggregate of 45% marks in Physics, Chemistry & Biology are eligible for Bachelor of Naturopathy and Yogic Sciences (BNYS). Bachelors program is usually of 5 1/2 years duration. However, many naturopathic schools have set their own prerequisites for entry and may require you to have a minimum of a bachelor's degree or equivalent.

Hope this helps!!!
