Here’s what you can do to appear for NEET after completing PCM without Biology:

1. NIOS Biology Course :

   • Enroll in the National Institute of Open Schooling (NIOS) to take Biology as an additional subject.
   • The NIOS certificate is valid for NEET eligibility as long as it meets the criteria set by NEET.

2. Re-appear for Board Exams :

   • You can consider reappearing for the Bihar Board exam with PCB (Physics, Chemistry, Biology).
   • Contact your school or the board’s regional office for re-registration details and policies for adding a new subject.

3. NEET Eligibility :

   • Ensure your additional Biology certificate covers the required NEET syllabus and meets the qualifying criteria (minimum 50% marks in PCB).

4. Time Management :

   • Prepare well in advance as you’ll need to balance both the new coursework and NEET preparation.

5. Consult Experts :

   • Talk to school authorities or educational counselors for personalized advice.
