The CSIR NET 2025 examination, conducted by the National Testing Agency (NTA), evaluates candidates for Junior Research Fellowship (JRF) and Lectureship/Assistant Professorship in five major science subjects: Chemical Sciences, Earth Sciences, Life Sciences, Mathematical Sciences, and Physical Sciences. The exam pattern includes three parts – A, B, and C, each designed to test different levels of understanding, ranging from general aptitude to advanced subject-specific analytical ability. Understanding the detailed syllabus is essential for systematic preparation, especially since the CSIR NET exam focuses heavily on conceptual knowledge, logical reasoning, scientific application, and research-oriented problem solving.
Table of Contents
CSIR NET Part A Syllabus (Common for All Subjects)
Part A is the General Aptitude section, mandatory for every candidate. It carries questions from:
1. Quantitative Aptitude
Number system
Fractions, decimals, algebra
Ratio, proportion, variation
Time and work
Time, speed, and distance
Mensuration & geometry
Permutation–combination and probability
2. Logical & Analytical Reasoning
Series and pattern recognition
Coding–decoding
Analytical puzzles
Data interpretation
Binary logic
Direction sense
Syllogism and Venn diagrams
3. Graphical & Data Interpretation
Line graph, bar graph, pie chart
Tabular data
Cartesian diagram analysis
Data comparison and inference
Part A emphasizes conceptual clarity and quick problem-solving rather than theoretical science knowledge.
CSIR NET Part B Syllabus (Subject-Specific MCQs)
Part B tests core subject knowledge and fundamental concepts. The syllabus differs for each discipline:
1. Chemical Sciences
Inorganic: Periodicity, coordination chemistry, reaction mechanisms
Physical: Thermodynamics, electrochemistry, quantum chemistry
Organic: Reaction mechanisms, stereochemistry, spectroscopy
2. Earth Sciences
Geology: Mineralogy, petrology, structural geology
Meteorology: Atmospheric processes, weather systems
Oceanography: Ocean structure, currents, marine geology
3. Life Sciences
Cell biology, genetics, evolution
Ecology, plant physiology, animal physiology
Biochemistry, immunology, biotechnology
4. Mathematical Sciences
Algebra, analysis, topology
Linear algebra, differential equations
Probability, numerical analysis
5. Physical Sciences
Classical mechanics, EM theory
Quantum mechanics, thermodynamics
Solid-state physics, electronics
Part B questions are direct, formula-based, and concept-driven.
CSIR NET Part C Syllabus (Higher-Order Analytical Questions)
Part C focuses on scientific application, research aptitude, and problem-solving skills. Questions are lengthy, conceptual, and require multi-step reasoning.
Chemical Sciences: Reaction pathways, spectroscopy-based deduction, advanced quantum chemistry
Earth Sciences: Geological interpretation, seismology, environmental modeling
Life Sciences: Experimental techniques, molecular interactions, advanced genetics
Mathematical Sciences: Proofs, theorems, advanced computational problems
Physical Sciences: Complex numerical problems, particle physics, advanced quantum theory
Part C contributes the highest marks, making strategic coverage essential.
