Ques: Is the passing mark the same across all subjects?
Ans: Not exactly. Pure theory subjects need 30 out of 100. Subjects with practicals split it: 21 in theory and 12 in practical, both separately.
Ques: What if I score 30 in theory but only 10 in practical?
Ans: You fail that subject. There is no averaging between the two. Both have to be cleared on their own terms.

Ques. Can I ask the board to give me grace marks?

Bihar Board 12th Grading System 2026
Bihar Board gives grades for Class 12 results. There are nine grades. The top grade is A1 for marks over 90%. The lowest is F if you get less than 33%. To pass a subject, you need at least 33%.
Here’s the complete grade chart:
| Marks Range | Grade | Performance Level |
|---|---|---|
| 91% and above | A1 | Outstanding |
| 81% - 90% | A2 | Excellent |
| 71% - 80% | B1 | Very Good |
| 61% - 70% | B2 | Good |
| 51% - 60% | C | Above Average |
| 41% - 50% | D | Average |
| 33% - 40% | E | Pass |
| Below 33% | F | Fail |
Once results are out, don't just check your score and move on. Look at your name, roll number, and marks on the marksheet carefully. Errors do happen, and a wrong entry can cause real trouble later. Spot something off? Tell your school immediately and carry the documents they ask for to get it fixed.
Ques. What is the minimum grade to pass Bihar Board 12th?
Ans: Grade E. That covers the 33%–40% marks range. Anything below is an F and means a fail.
Ques. Does your grade affect college admission chances?
Ans: Yes, significantly. Most good colleges and scholarship schemes look for at least B2 or above. Passing with an E grade clears the board exam but limits your options for competitive admissions.
Division System: First, Second & Third Division
Along with grades, Bihar Board also awards divisions based on your total marks out of 500.
| Percentage | Marks | Division |
|---|---|---|
| Above 60% | More than 300 | First |
| 45% - 59% | 225 - 300 | Second |
| 33% - 44% | 150 - 225 | Third |
| Less than 33% | Less than 150 | Fail |
Ques. Is First Division needed for college admission?
Ans: For government colleges and most state scholarships, it’s usually expected. Private colleges don’t always follow the same rule.
Ques. What if I score exactly 300 out of 500?
Ans: 300 sits right at the First Division line. It’s better to check what’s actually printed on your marksheet.
What Happens If You Fail? Compartment Exam 2026 Rules
Not everyone clears every subject and Bihar Board knows that. That's why the compartment exam exists, so one bad paper doesn't cost you the whole year.
Who Can Sit for It?
Students who failed in one or two subjects can appear. More than two fails, and you're looking at a full repeat next year.
Dates to Save
Tentatively, compartment exams run from April 19 to May 11, 2026. The official schedule will go up on biharboardonline.gov.in, check it regularly.
What's at Stake?
Pass it and your certificate is ready, college admissions stay on track. Don't pass it and the full board exam next year becomes your only option. The bottom line is treat the compartment like your main exam. For many students, it genuinely is.

Ques. Can I appear in the compartment exam if I failed three subjects?
Ans: No. Compartment is strictly for students who failed in one or two subjects. Three or more fails means a full repeat in the next academic year.
Ques. Will compartment marks show separately on my marksheet?
Ans: Yes. It will be marked as "Compartment Passed." The score from that exam is recorded officially on your certificate.
Re-Evaluation & Re-Checking: How to Apply
Bihar Board gives you two ways to challenge your result, use the right one based on your situation.
- Scrutiny (Re-Checking):
This isn't a full re-evaluation. Scrutiny only checks if all answers were seen and marks were totalled correctly. If you suspect a counting error or a skipped answer, this is your option. Apply online through the official Bihar Board portal.
- Re-Evaluation:
This is the deeper check, your entire answer sheet gets reviewed again. A fee applies, and whatever result comes out of it is final. No further appeals after this.
- One Thing Don't Miss:
Both options come with a deadline, announced right after results. Miss that window and neither option stays open for you.
So the moment results are out, don't sit on it. Check your marks, decide fast, and apply before the date is gone.
For a clear idea of the process, you can look up Rishikesh Kumar’s YouTube video on applying for Bihar Board 12th Scrutiny 2026
Ques. What's the actual difference between scrutiny and re-evaluation?
Ans: Scrutiny checks if marks were added correctly and no answer was left unchecked. Re-evaluation means a full fresh review of your entire answer sheet — completely different in scope.
Ques. What if re-evaluation gives me lower marks than before?
Ans: Yes, it can happen. Your marks can go up, drop, or stay exactly the same, there's no guarantee either way. The result that comes out is final, no second chances after that. So don't apply just because you're unhappy with your score. Apply only if you genuinely spotted something wrong in the checking.
