Bihar Board 12th Physics Sent Up Answer Key 2025
How can I score 180 in neet physics ?
Hi Aryan,
Hope you are doing well. As you are planning to gain expertise in the physics subject in NEET exam, I should suggest you that you need to follow certain steps before starting your preparations in the subject.
First and foremost, Identify the chapter/topics/concepts are going to be asked in the session in which you are appearing for exam. Visit the official NTA website to be sure about the syllabus and content first. After that you need to analyse each and every chapter by covering all the subtopics residing in a particular chapter. No here comes the crucial part try to identify your weak areas by attempting mock-tests and topic wise tests. Analyse the result and your performance subjected to each topic. One thing to note down that this process should get completed before 5 to 6 months of your exam day so that in this time span you can truly focus upon the execution part of the test i.e. time analysis and improvising your weak areas. Last but not the least stay patient and enthusiastic and take care of your physical and mental health.
Hope this helped.
My subjects are Biology, Chemistry, Psychology, English and Bengali. Im in class 12th rn. And everyone says that without physics i cant do anything, Cant give any entrance exams like Jee or Neet and Cant go for normal courses like medical or engineering. Is it true? What should I do?
It’s a common misconception that students without Physics as a subject have limited career options. While it's true that Physics is mandatory for certain fields like engineering (JEE) and medicine (NEET), there are numerous alternative paths you can explore based on your current subjects—Biology, Chemistry, Psychology, English, and Bengali. Here's a breakdown of your options:
Fields You Can Explore Without Physics
-
Biology-Centric Fields :
- B.Sc. in Biology, Botany, or Zoology : Focus on research or teaching.
- B.Sc. in Biotechnology or Microbiology : Growing fields with applications in healthcare and agriculture.
- Environmental Science : Careers in sustainability and conservation.
- Food Technology : Opportunities in the food and beverage industry.
-
Psychology and Related Areas :
- B.A./B.Sc. in Psychology : Lead to careers in counseling, clinical psychology, or organizational psychology.
- Social Work : Work in community services, NGOs, or mental health advocacy.
-
Healthcare and Allied Courses :
- B.Sc. Nursing : A high-demand profession in healthcare.
- Pharmacy (B.Pharm) : Focus on medicine and pharmaceuticals.
- Dietetics and Nutrition : Careers in fitness, wellness, and healthcare.
- Physiotherapy (BPT) : Healthcare profession helping patients recover mobility.
-
Language and Communication :
- B.A. in English, Bengali, or Linguistics : Writing, editing, teaching, or translation careers.
- Mass Communication and Journalism : Opportunities in media, PR, or advertising.
-
Other Professional Degrees :
- Law (BA LLB) : A promising career in law and justice.
- Management (BBA) : Entry into business and corporate sectors.
Key Insights
- No JEE/NEET Without Physics : Unfortunately, Physics is mandatory for both JEE and NEET, as they are designed for engineering and medical professions requiring a strong foundation in Physics.
- Focus on Strengths : You have Psychology, Chemistry, and Biology, which open doors to unique and growing fields like psychology, healthcare, and environmental studies.
What You Can Do Next
- Explore Your Interests : Identify whether you're inclined towards science (biology-based fields), humanities (psychology, language), or professional degrees (law, management).
-
Research Entrance Exams and Eligibility
:
- For courses like B.Sc. Nursing, Biotechnology, or Psychology, check the eligibility criteria of universities.
- Some courses may require an entrance test or are merit-based on 12th-grade marks.
- Consult a Career Counselor : A professional counselor can help map out your options and guide you to a suitable path.
Physics is not the only route to a successful career. Your current subjects give you diverse opportunities—focus on your strengths and passions to shape your future! If you’d like more specific guidance on a particular field, let me know.

Solving problems in physics, sometimes we use conservation of momentum and sometimes we use conservation of kinetic energy relation when should we use both of the like which all cases can come? Mention all the cases where we use each of these
n physics problems, the use of conservation of momentum and conservation of kinetic energy depends on the type of collision or interaction. Here's when to use each:
1. Conservation of Momentum
- Applicable to all types of collisions and interactions.
- Momentum is always conserved in a system where no external forces act.
Common Cases:
-
Elastic Collisions
- Momentum is conserved.
- Kinetic energy is also conserved.
- Example: Billiard balls colliding.
-
Inelastic Collisions
- Momentum is conserved.
- Kinetic energy is not conserved (some is lost as heat, sound, etc.).
- Example: Car crashes.
-
Perfectly Inelastic Collisions
- Momentum is conserved.
- Kinetic energy is not conserved.
- The objects stick together after the collision.
- Example: A lump of clay sticking to a moving cart.
-
Explosion Problems
- Momentum is conserved.
- Kinetic energy is not conserved (energy is released in different forms).
- Example: A bomb exploding into fragments.
2. Conservation of Kinetic Energy
- Only applicable in elastic collisions.
- In inelastic or perfectly inelastic collisions, kinetic energy is not conserved.
Common Cases:
-
Elastic Collisions
- Use both conservation of momentum and kinetic energy.
- Example: Two balls colliding with no energy loss.
When to Use Both Conservation of Momentum and Kinetic Energy
-
Elastic Collisions:
- Both momentum and kinetic energy are conserved.
- Example: Collisions between gas molecules in ideal conditions.
Summary:
Collision Type | Momentum Conservation | Kinetic Energy Conservation | Example |
---|---|---|---|
Elastic Collision | Always | Yes | Billiard balls colliding |
Inelastic Collision | Always | No | Car crash |
Perfectly Inelastic | Always | No | Objects sticking together |
Explosion | Always | No | Bomb exploding into fragments |

However, the question papers for Biology and Mathematics are separate and specific to each group.
Here's a breakdown of the MH-CET exam structure:
PCB Group
1. Physics and Chemistry (combined paper)
2. Biology
PCM Group
1. Physics and Chemistry (combined paper)
2. Mathematics
The combined Physics and Chemistry paper consists of 100 marks, with 50 marks allocated to each subject. The duration of this paper is 90 minutes.
Please note that the exam pattern and structure may be subject to change. It's always a good idea to check the official MH-CET website or contact the exam authorities for the most up-to-date information.
Have a great day

- Review the eligibility criteria and application process for re-examinations.
-
Apply for Re-Exam as a Private Candidate:
- Most boards allow failed students to register for the next academic year as private candidates.
- The application forms for private candidates are usually released online. Fill them before the deadline.
-
Prepare for Physics and Math:
- Focus on the subjects you failed in. Consider joining a tuition center or taking help from online resources to strengthen your understanding.
-
Exam Schedule:
- Once registered, you will receive details about your exam schedule, center, and admit card.
Why You Shouldn't Give Up:
- Second Chances Are Normal: Failing doesn’t mean the end; it’s a chance to learn and improve.
- Future Opportunities: Completing Class 12 opens doors to various academic and career paths.
Additional Tips:
- Take small, consistent steps to prepare for Physics and Math.
- If you feel stressed, consider reaching out to a counselor for guidance and motivation.
You’ve got this—keep going!
