Yes as per NEET eligibility cutoff if you are from general category then you need 50% or aggregate and above to be eligible and for reserved category its 40%. Now your entry into paramedical courses like physiotherapy, ayurvedic, etc. that will be based on your NEET merit scores only. And other paramedical courses like BSC Nursing, first aid, B.Sc. in Optometry, B.Sc. in Operation Theater technology, B.Sc. in Audiology and speech therapy etc. for them your boards marks are enough.
