hello,

If you have completed your graduation but did not recieved the degree then you have to upload your final year marksheet. If in the application some remark given then you have to contact with the NIMCET authorities, they will solve your problem as soon as possible. But if nothing extra is mentioned you can upload your final  year marksheet then after the procedure if you get your UG Degree then you will have to submit there.

all the best!!
