Hello Student,

Grace marks will not affect your selection during NEET counseling or admission as long as you have passed your 12th-grade exams and meet the eligibility criteria. NEET counseling primarily focuses on your NEET score and rank, not how you passed individual subjects in your board exams.
As per NEET eligibility criteria, candidates need to secure at least 50% aggregate marks in Physics, Chemistry, and Biology (40% for reserved categories) in their 12th-grade board exams. If you meet this requirement, you should be eligible for admission.
However, you can always double-check with specific counseling authorities or colleges, as some institutions may have their own rules regarding board exam marks.

Thankyou. Good luck!
