Yes, you can. If you do 11th from CBSE in 2025 and 12th from NIOS in 2026, then you are allowed to attempt JEE. NIOS is a valid board, so you can give JEE in 2026 and again in 2027. Just take admission on time and pass your 12th exams.
If you want to do a BFA through ODL (Open and Distance Learning), it’s important to choose a UGC-approved university for your degree to be valid. Make sure the university offers a recognized BFA program via distance mode. Check the UGC official website or the university’s accreditation before applying.
