My NIOS marksheet says 'xxxx' even though I passed, will this affect my NTA application?

I have passed class 12th from Maharashtra board with PCB and English and Hindi but I got less than 50% marks in PCB so I appeared in nios on demand exam for only one subject biology to fulfill eligibility criteria required for neet and admission in mbbs now I have 2 marksheets one from nios board which consists only biology and one marksheet from state board can I use PC from Maharashtra board and biology from Nios marksheet at the time of addmission???

If I gave improvement exam of all three subjects PCB from nios and cross 50% criteria can I use my 5 subject state board marksheet (PCB+ 2 subjects) and Nios marksheet ( only PCB ) at the time of admission and councelling?????

I haven't paid the feese yet sir so I can change it now.. sir many nios public exam students chose code 1 and I am only giving on demand from nios for chemistry only sir its gonna be alright right? If I bring my nios marksheet even though it wasn't in neet form ? I talked to my 10+2 school teacher he also said to select Code 2 and the nta helpine also told me to select Code 2 but all the previous nios students are telling me to select Code 1 as what am I gonna put in chemistry marks as nios results isn't out yet. Everbody says no one really cares in counciling they only gonna see your marks and if its meeting 50% criteria or not.. Should I put my cbse less chemistry marks in neet form? Sir? And during counseling show them the nios result one subject marksheet of chemistry..??

I completed my 12th State Board in 2025 with Physics, Chemistry, Computer Science, and Mathematics. I now want to apply for a college course that requires Biology, and the college has informed me that they accept NIOS qualifications but require all three subjects - Physics, Chemistry, and Biology, not just Biology alone. I have already applied for the NIOS On-Demand Biology exam scheduled in March 2026. I would like clarification on the following: 1. Should I write the Biology On-Demand exam in march and then later apply for Physics and Chemistry through NIOS On-Demand as well, or is it better to enroll for the NIOS Public Exam and write all five subjects (English, Physics, Chemistry, Mathematics, Biology) together to obtain a single consolidated 12th passing certificate instead of separate marksheets? 2. If I take the Biology exam now and pass or fail, am I allowed to appear for the Biology exam again in the NIOS Public Exam session? Will they accept my admission for 12th public exam after taking biology on demand? 3. Since I have already completed my State Board 12th and passed all the subjects, am I eligible to apply for a full NIOS Public Exam with five subjects or can I only apply for on demand exam? Which option on demand or public exam is best to obtain a full 12th passing certificate from nios? I thought it is best to take the full public exam for 12th STD in NIOS instead of getting seperate marksheet for each subject so that I can get my college admission smoothly. Kindly guide me on which option is officially recommended for smooth college admission eligibility.
