Paper 1 is common for all subjects and contains 50 multiple-choice questions (MCQs).
Paper 2 is subject-specific (Physics in this case) and contains 100 MCQs.
Each question in both papers carries 2 marks.
The medium of the question papers is English and Hindi.
UGC NET 2025 Exam: Marking Scheme
Each correct answer awards 2 marks.
There is no negative marking for incorrect answers.
Candidates are encouraged to attempt all questions as no marks are deducted for wrong or unanswered questions.
The aggregate score is the sum of marks obtained in both Paper 1 and Paper 2.

Preparation Tips for UGC NET Physics 2025 Exam
Students, to prepare well for the UGC NET Physics 2025 exam, follow a structured study plan. Study 4–6 hours daily with full focus. Start with core topics like Mathematical Methods of Physics, Classical Mechanics, Electromagnetic Theory, Quantum Mechanics, and Thermodynamics & Statistical Physics. Cover key chapters such as vector calculus, Lagrangian mechanics, Maxwell's equations, Schrödinger equation, and statistical laws.
Use the initial weeks to understand basic concepts and solve questions from Part A. Then move on to advanced topics in Parts B and C. These include Atomic & Molecular Physics, Condensed Matter Physics, and Nuclear Physics. Revise regularly and solve previous year papers and mock tests to improve speed and accuracy.
Take short breaks during study sessions. Do weekly self-assessments to track your progress. Focus more on weak areas for complete preparation.

Mukesh Ambani donates ₹151 crore to alma mater ICT
MUMBAI: Industrialist Mukesh Ambani on Friday announced an unconditional grant of ₹151 crore to his alma mater, the Institute of Chemical Technology (ICT, formerly UDCT), Mumbai. The donation was made in honour of Prof M M Sharma, on the occasion of the release of his biography Divine Scientist, published in both Marathi and English. Ambani shared personal memories of Prof Sharma, recalling how the first lecture he attended by him shaped his path. 'Like my father Dhirubhai Ambani, he had a burning desire to change Indian industry from scarcity to global leadership,' said Ambani. 'These two bold visionaries believed that science and technology, in alliance with private entrepreneurship, would open the floodgates of prosperity.' Crediting the rise of the Indian chemical industry to Prof Sharma's efforts, Ambani called him a 'Rashtra Guru' and 'a Guru of Bharat.' Ambani said the ₹151 crore unconditional donation was his guru dakshina made as per Prof Sharma's instruction. 'When he tells us something, we just listen. We don't think,' Ambani said. The event was held at ICT's Pidilite Hall and presided over by senior nuclear scientist Anil Kakodkar. Several eminent scientists, including Raghunath Mashelkar, J B Joshi, Aniruddha Pandit, and G D Yadav, paid tribute to Prof Sharma's legacy in education and science. Divine Scientist was written in Marathi by Anita Patil and translated into English by Sonia Khare. Prof Sharma, who joined UDCT as a professor at 27, has dedicated over six decades to teaching and research. His former students, many of whom went on to become pioneers in Indian science, recalled his influence and humility.
