The Joint Entrance Screening Test (JEST) typically employed negative marking for incorrect answers. Negative marking is a practice where a fraction of marks is deducted for each wrong answer. This policy is meant to discourage random guessing and encourage candidates to answer questions they are reasonably confident about.

-1 marks will be deducted for every wrong answer marked in section A and -3 will be deducted in section B.

However, please note that examination policies and procedures can change over time, and specific details, including whether or not negative marking is applied, may vary from one year to another. To get the most accurate and up-to-date information regarding the examination pattern, including the presence or absence of negative marking, it is recommend checking the official JEST website or referring to the official notification for the specific year's examination.

Candidates should always stay informed about the latest policies and guidelines related to the JEST examination to prepare effectively and make informed decisions during the exam.

Yes, candidates appearing for the JEST physics exam should prepare for specific topics that are typically covered in the syllabus. While the syllabus may vary slightly from year to year, the following are some common topics that candidates should be familiar with when preparing for the JEST physics exam:

1. Classical Mechanics: Laws of motion, gravitation, rotational dynamics, and oscillations.

2. Electromagnetism: Electromagnetic waves, electric and magnetic fields, Maxwell's equations, and electromagnetic radiation.

3. Quantum Mechanics: Wave-particle duality, Schrödinger equation, quantum states, and quantum mechanical operators.

4. Thermodynamics and Statistical Physics: Laws of thermodynamics, kinetic theory, statistical mechanics, and entropy.

5. Relativity: Special and general relativity, time dilation, and space-time curvature.

6. Mathematical Methods: Complex analysis, linear algebra, differential equations, and Fourier analysis.

7. Atomic and Molecular Physics: Atomic structure, molecular structure, and spectroscopy.

8. Nuclear and Particle Physics: Nuclear structure, elementary particles, and nuclear reactions.

9. Condensed Matter Physics: Crystal structure, semiconductors, and properties of materials.

10. Optics: Wave optics, ray optics, and interference and diffraction phenomena.

11. Electronics: Semiconductor devices, operational amplifiers, and digital circuits.

12. Mathematical Physics: Partial differential equations, vector calculus, and linear algebra.

It's important for candidates to review the specific syllabus provided on the official JEST website or by the participating institutions since the syllabus may be subject to change. Additionally, candidates should focus on their strengths and interests within the field of physics while preparing for the exam.

The Joint Entrance Screening Test (JEST) primarily covers the following fields of study:

1. Physics: JEST is most well-known for its coverage of physics-related programs. It serves as a qualifying exam for Ph.D. and integrated Ph.D. programs in various areas of physics, including but not limited to astrophysics, condensed matter physics, high-energy physics, nuclear physics, and theoretical physics.

2. Theoretical Computer Science: JEST also includes theoretical computer Science as one of its covered fields. It is used for admission to Ph.D. programs in theoretical computer Science and related areas.

3. Neuroscience: JEST is applicable to Ph.D. programs in neuroscience, allowing candidates interested in this interdisciplinary field to seek admission to prestigious research institutions.

It's important to note that while JEST primarily covers these fields, the participating institutions and their specific programs may have variations in their eligibility criteria and areas of research. Therefore, candidates should check the official JEST website or the websites of the participating institutes for the most up-to-date information on the programs offered and their eligibility requirements.
