In the context of the Board of Secondary Education, Assam (SEBA), the minimum passing mark for each subject, including Physics, is typically 30%. This means you would need to score at least 30 out of 100 marks to pass. If you've scored 15 marks in Physics, you're below this threshold.

Regarding grace marks, SEBA's policies can vary annually, and specific details about the allocation of grace marks for the 2025 board exams haven't been publicly detailed as of now. Grace marks, when awarded, are usually limited and may not be sufficient to bridge a significant gap like the one between 15 and 30 marks.

Concerning the role of optional subjects, SEBA has provisions where an elective (optional) subject can replace a failed compulsory subject under certain conditions. This means if you fail in one of the main subjects but score well in your optional subject, the marks from the optional subject can substitute for the failed subject, potentially allowing you to pass overall. However, this substitution policy typically applies when a student fails in only one subject. Failing in multiple subjects may not be compensated by optional subjects.

It's important to note that educational boards periodically update their examination and passing criteria. For the most accurate and current information regarding passing marks, grace marks, and the role of optional subjects for the 2025 board exams, it's advisable to consult the latest notifications directly from SEBA or speak with your school's examination authority.

Here are some of the most expected MCQs for 12th CBSE Physics 2025:

Hello there,

In the HSC Physics exam, if you did not fully write the answers to the MCQs but mentioned the option numbers (like A, B, C, etc.), and the answers are correct, typically:

1. If the instructions clearly ask for only the option letter (A, B, C, etc.), and you have marked it correctly, you should not face any mark deduction.
   
   

2. However, if the instructions require you to write the full answer and you only mentioned the option letters, some examiners might not award full marks depending on how strictly the instructions are followed.

To be safe, always ensure to follow the exam instructions carefully. If it was just marking the correct option and it matches the answer key, you should get full marks for that question.

I hope this answer helps you. If you have more queries then feel free to share your questions with us we will be happy to assist you.

Thank you and wishing you all the best for your bright future.

Hello there,

No, you cannot appear for the 2025 improvement exam for Physics if you have already taken an improvement exam in 2024. Most boards allow only one attempt for improvement per subject, which must be taken in the immediate following year of passing (i.e., 2024 in your case).

However, some state boards and open schooling systems may have different rules. Check with your respective board for clarification.

I hope this answer helps you. If you have more queries then feel free to share your questions with us we will be happy to assist you.

Thank you and wishing you all the best for your bright future.

Hello,

If you have registered for the Improvement Exam in Physics, Chemistry, and Mathematics (PCM) but fail to attempt the Physics exam, your marksheet will reflect the following:

1. Your previous year's Physics marks will be retained.
2. The marks for Chemistry and Mathematics (if attempted) will be updated with the new scores.
3. The Physics column may show " Absent " or retain old marks, depending on the board’s policy.
4. Your final result will be based on the best marks among both attempts.
5. You might not get a consolidated improvement certificate if one subject is missing.

Hope you find it useful !

Hello

Yes , a postgraduate Physics student can apply for ISRO ICRB exams for roles like Scientist/Engineer SC (Physics) and Junior Research Fellowships (JRF).

Eligibility requires an MSc in Physics with at least 65% marks . Some ISRO centers also recruit for research and technical positions in space science and remote sensing.

hope this helps you .
