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. Some good options include universities like IGNOU or other state open universities. Always confirm the course details and fee structure before enrolling.
