Even though you passed Class 12 with PCM, you can still appear for NEET in 2026 if you complete Biology as an additional subject, either through NIOS or as a private candidate from a recognized board. NEET eligibility requires Physics, Chemistry, Biology/Biotechnology with English. Start preparing with NCERT Biology books (Class 11 & 12), followed by standard practice books like Trueman’s Biology and MTG NEET guides. Also, enroll in a NEET-focused coaching program (online/offline) and aim to give mock tests regularly. You have enough time to build a strong foundation and crack NEET 2026.
