There is normally no maximum age limit for participation in AYUSH Counselling for the majority of AYUSH courses in India, as per my understanding cutoff in September 2021.
Candidates must, however, be at least 17 years old at the time of admission, which is the minimum age requirement.
The age eligibility requirements may change a little depending on the laws of the particular state or college.
For the most current and correct information on age restrictions for AYUSH Counselling, please refer to the official counselling notification or the admission brochure of the relevant college.
Please check the most recent instructions for any modifications made after my knowledge cutoff date.
