Hello Aspirant,

No, you don’t have to pay the whole 5 years fee at once. But yes, you have to pay the admission fee, tuition fee, hostel fee, library fee and whatever fee are applicable for the first year.
Secondly, if you are thinking of preparing for NEET while taking admission in BAMS, that’s good for you. Make sure you have a time table and to do list. May you succeed in your life. Thank you.
