Can NEET(AIQ)can convert PH1seat to PH2 if PH1 seat remain unfilled.Is there any allotment to fill that seats?

Yes, if the seat is vacant then it converts, also the session is aleardy over but generally you can check the criteria for the same below -

3% seats are reserved on horizontal basis for Physically Handicapped candidates (only for locomotor disabilities of lower limbs between 50% to 70%, provided that in case any seat in this 3% quota remains unfilled on account of unavailability of candidates with locomotor disability of lower limbs between 50% to 70% then any such unfilled seat in this 3% quota shall be filled up by persons with locomotor disability of lower limbs between 40% to 50% before they are included in the seats of respective category) in 15% All India UG quota seat.

Hope this helps!!!
