With a score of 126 in PCB (Physics, Chemistry, Biology) in your 12th board exams, it might be difficult to meet the eligibility criteria for NEET, even if you belong to a reserved category.

NEET Eligibility Criteria:

• Minimum PCB Score: For reserved categories (SC/ST/OBC), the minimum required percentage in PCB is 40%, which usually translates to around 132 out of 300 marks.
  
  
• Eligibility: If your score does not meet this requirement, you would not be eligible to appear for NEET.
