The National Institute of Open Schooling (NIOS) has released the latest 12th Class physics syllabus on the official website. The NIOS 12th physics syllabus comprises both theoretical and practical components. The NIOS Class 12 physics theory part is made up of eight core modules that cover essential physics concepts and phenomena. These modules focus on foundational topics such as mechanics, electricity, light, and other areas of physics, providing the basic knowledge required for more advanced areas of study. The final module, Module VIII, is application-oriented and focuses on specific fields like semiconductors, electronics, and communication.

Hey Sapna:)

Thanks for reaching out!

Yes, NIOS offers physical classes called personal contact program(PCP) at its study centre across india. These classes are meant to help students of both class 10th and 12th by providing doubt clarification, practical demonstration and guidance.These sessions are usually held on weekends or holidays, attendance is not mandatory but recommended.

You can find nearby centres and their schedules using the official NIOS Study Centre Locator.

According to the eligibility criteria for JEE Advanced, the candidates must have appeared in Class 12th and scored 75% aggregate marks. For the first time, you appeared in the CBSE Class 12 board exam in 2024, and in 2025, you appeared in the 12th examination from the NIOS board and scored 75%. Since NIOS is a recognised board, and you fulfil the aggregate marks, you are eligible to appear in JEE Advanced 2026 .

Yes, you can definitely appear for the 12th again through NIOS with PCM subjects.

This will make you eligible for JEE exams.

However, your previous PCMB degree will still hold validity. It won't be replaced or affected by the new NIOS certificate. You'll essentially have two 12th certificates.

Important Considerations:

  • Time Management: Balancing NIOS studies and JEE preparation will be challenging.
  • Eligibility Criteria: Ensure you meet the specific eligibility criteria for JEE, especially regarding age limits and other requirements.
  • Exam Strategy: Develop a focused study plan to excel in both NIOS exams and JEE preparation.

Remember: While this is a potential path, carefully evaluate if it aligns with your long-term goals and if you're prepared for the academic and time commitment involved.

hope this helps you!!

Here are the key points regarding your query about appearing for NEET or IISER exams after passing 12th board in 2023 with 53% overall marks and appearing for biology improvement through NIOS:

1. NEET Eligibility:

- For NEET (National Eligibility cum Entrance Test), the minimum eligibility criteria is 50% marks in Physics, Chemistry, and Biology/Biotechnology subjects in the 12th board exam.

- Since your overall 12th board marks are 53%, you would be eligible to appear for NEET, provided you score at least 50% in the individual subjects of Physics, Chemistry, and Biology.

- Appearing for biology improvement through NIOS should not affect your NEET eligibility, as long as you meet the 50% criteria in the individual subjects.

2. IISER Eligibility:

- For admission to the Indian Institutes of Science Education and Research (IISERs), the eligibility criteria includes scoring a minimum of 60% marks in the 12th board exam (55% for SC/ST/PwD categories).

- With your overall 12th board marks being 53%, you would not meet the general category eligibility criteria for IISER.

- However, if you are able to improve your overall 12th board marks to 60% or above (55% for SC/ST/PwD) through the biology improvement exam, then you would become eligible to appear for the IISER Aptitude Test (IAT) 2024.

- For NEET, your 53% overall 12th board marks along with the 50% individual subject criteria should make you eligible, provided you clear the biology improvement exam.

- For IISER, your current 53% overall 12th board marks do not meet the 60% (55% for SC/ST/PwD) eligibility criteria. You would need to improve your overall marks to 60% or above to be eligible for the IISER Aptitude Test 2024.


I hope this helps provide clarity on your eligibility for NEET and IISER exams. Let me know if you have any other questions.



hello

Yes, it is theoretically possible to pursue engineering while simultaneously preparing for and attempting the NEET exam, and then switch to a medical college later. However, there are several important factors and considerations you should be aware of:


1. **Dual Enrollment and Exam Preparation**


- **Engineering Studies:** While you are enrolled in an engineering college, you will need to manage your time effectively to balance both your engineering coursework and NEET preparation. This can be challenging, as engineering programs can be demanding.


- **NIOS for Biology:** If you are pursuing the National Institute of Open Schooling (NIOS) for Biology to meet the eligibility requirements for NEET, ensure that you complete the necessary coursework and exams as per the NIOS schedule.

2. **Eligibility for NEET**


- **NEET Eligibility:** Ensure that you meet all the eligibility criteria for NEET, including the age limit, educational qualifications, and other requirements. NEET is typically open to students who have completed their 10+2 with Physics, Chemistry, and Biology.


- **Attempting NEET:** You can attempt NEET while being enrolled in an engineering college. Many students take a gap year or study part-time to prepare for competitive exams like NEET.

3. **Switching to Medical College**


- **Admission Process:** If you qualify for NEET and secure a place in a medical college, you would need to follow the admission process specific to that institution. This might involve withdrawing from your engineering program and fulfilling any other requirements of the medical college.


- **Credit Transfer:** Engineering credits and coursework generally do not transfer to medical college, so you would essentially be starting from scratch in the medical program.


4. **Considerations and Challenges**


- **Time Management:** Balancing engineering studies with NEET preparation requires excellent time management skills. Engineering programs can be rigorous, and managing additional study time for NEET might be demanding.


- **Financial Implications:** Consider the financial implications of switching from an engineering college to a medical college. You might face costs related to tuition fees, examination fees, and potentially the loss of time spent in the engineering program.


- **Commitment:** Ensure that you are fully committed to pursuing a career in medicine before making any decisions. Medical education is demanding and requires a strong commitment to the field.

5. **Alternative Paths**


- **Drop Year:** Some students choose to take a year off after completing their 12th grade to prepare exclusively for NEET, which can be less stressful than juggling both engineering studies and NEET preparation.


- **Integrated Programs:** Some institutions offer integrated programs that combine engineering and medical studies, but these are rare and may not be available everywhere.
