If you are searching for the CSIR NET syllabus 2026, the safest way to prepare is to follow the subject-wise syllabus hosted on the official CSIR-HRDG website and match it with the current exam structure shown on the official CSIR NET pages. The syllabus is not one generic science paper. It is divided into five separate subjects, and each subject has its own Part B and Part C content, while Part A remains common for everyone.
One important 2026 update is that CSIR-HRDG issued a stakeholder consultation notice dated 13 April 2026 for proposed revised syllabi in four subjects: Chemical Sciences, Earth, Atmospheric, Ocean and Planetary Sciences, Mathematical Sciences, and Physical Sciences. That means candidates should not rely on random summary pages or coaching notes alone. Until a finalized revised syllabus is officially adopted, the current official syllabus links remain the practical reference for preparation.
Below is a clean, subject-wise guide to the latest official CSIR NET syllabus, including the common Part A, subject list, exam pattern differences, major topics in each paper, and direct official PDF links. This is designed for candidates who want to know exactly what to study first and how the official syllabus is structured.
What counts as the latest official CSIR NET syllabus in 2026
The latest reliable source for CSIR NET syllabus 2026 is the official syllabus section on the CSIR-HRDG website. NTA's official CSIR NET bulletin also directs candidates to CSIR-HRDG for the subject-wise syllabus and scheme of examination.
For 2026, there is one important update: CSIR-HRDG published a consultation notice on 13 April 2026 for proposed revised syllabi in four subjects: Chemical Sciences, Earth, Atmospheric, Ocean and Planetary Sciences, Mathematical Sciences, and Physical Sciences. Because that notice is framed as a proposal and consultation exercise, candidates should use the currently hosted official syllabus PDFs unless and until a final revised syllabus is formally adopted for a specific exam cycle.
Life Sciences is slightly different. On the official Life Science and Biotechnology page, CSIR-HRDG separately shows a syllabus link marked for use up to the exam cycle June 2026, along with a revised syllabus link. That makes it especially important for Life Sciences candidates to download the current official file from the subject page instead of depending on copied summaries elsewhere.
CSIR NET 2026 subject list
The Joint CSIR-UGC NET is conducted in five science subjects. You choose one subject while applying, and your Parts B and C come from that selected subject only.
| Subject Code | Subject |
|---|---|
| 701 | Chemical Sciences |
| 702 | Earth, Atmospheric, Ocean and Planetary Sciences |
| 703 | Life Sciences |
| 704 | Mathematical Sciences |
| 705 | Physical Sciences |
If you are starting preparation, confirm your subject first. Many candidates lose time by reading the wrong syllabus because the overall exam name is common but the actual subject content is different for each paper.
CSIR NET 2026 exam pattern linked to the syllabus
The paper is a single test of 200 marks and 3 hours. Part A is common across subjects. Parts B and C depend on the chosen subject and do not have the same structure in every paper.
Common Part A for all subjects: 20 questions are given, 15 must be answered, each question carries 2 marks, total 30 marks.
| Subject | Part B | Part C | Negative Marking |
|---|---|---|---|
| Chemical Sciences | 40 questions, answer 35, 2 marks each, total 70 | 60 questions, answer 25, 4 marks each, total 100 | 25% negative marking for wrong answers |
| Earth, Atmospheric, Ocean and Planetary Sciences | 50 questions, answer 35, 2 marks each, total 70 | 80 questions, answer 25, 4 marks each, total 100 | 25% negative in Part A and B; 33% negative in Part C |
| Life Sciences | 50 questions, answer 35, 2 marks each, total 70 | 75 questions, answer 25, 4 marks each, total 100 | 25% negative marking for wrong answers |
| Mathematical Sciences | 40 questions, answer 25, 3 marks each, total 75 | 60 questions, answer 20, 4.75 marks each, total 95; multiple correct options in Part C | 25% negative in Part A and B; no negative marking in Part C |
| Physical Sciences | 25 questions, answer 20, 3.5 marks each, total 70 | 30 questions, answer 20, 5 marks each, total 100 | 25% negative marking for wrong answers |
This subject-wise difference matters because your preparation strategy should match both topic coverage and question-selection rules.
CSIR NET Part A syllabus 2026
Part A is common to all five subjects. According to the official CSIR-HRDG exam scheme pages, this section covers General Science, Quantitative Reasoning and Analysis, and Research Aptitude.
- General Science
- Quantitative Reasoning and Analysis
- Research Aptitude
This section is smaller in marks than the subject-specific parts, but it is still important because it is common to every candidate and can improve the overall score if prepared steadily. A practical approach is to revise Part A throughout the preparation cycle rather than leaving it for the final week.
CSIR NET Chemical Sciences syllabus 2026
The official Chemical Sciences syllabus is structured in four broad blocks: Inorganic Chemistry, Physical Chemistry, Organic Chemistry, and Interdisciplinary Topics.
- Inorganic Chemistry: periodicity, bonding, acids and bases, main group chemistry, coordination compounds, inner transition elements, organometallics, clusters, analytical methods, bioinorganic chemistry, spectroscopic characterization and nuclear chemistry.
- Physical Chemistry: quantum mechanics, spectroscopy, thermodynamics, statistical thermodynamics, electrochemistry, chemical kinetics, colloids and surfaces, solid state, polymer chemistry and data analysis.
- Organic Chemistry: stereochemistry, aromaticity, reactive intermediates, reaction mechanisms, named reactions, functional group interconversion, retrosynthesis, asymmetric synthesis, pericyclic reactions, heterocycles, natural products and spectral structure determination.
- Interdisciplinary Topics: chemistry in nanoscience and technology, catalysis and green chemistry, medicinal chemistry, supramolecular chemistry and environmental chemistry.
Chemical Sciences candidates should prepare the syllabus in blocks instead of as a single long list. The official PDF is especially useful because it shows the exact scope expected under each branch.
CSIR NET Earth, Atmospheric, Ocean and Planetary Sciences syllabus 2026
The official Earth Sciences syllabus is one of the broadest papers in the exam. Part B begins with five major areas and Part C moves into deeper domain-wise coverage.
Part B broad areas:
- The Earth and the Solar System
- Earth Materials, Surface Features and Processes
- Interior of the Earth, Deformation and Tectonics
- Oceans and Atmosphere
- Environmental Earth Sciences
Advanced Part C coverage includes:
- Geology topics such as mineralogy, petrology, structural geology, geotectonics, stratigraphy, paleontology, sedimentology, metamorphism and crustal evolution
- Applied Geology and Physical Geography, including remote sensing, GIS, engineering geology, mineral exploration, hydrogeology, geomorphology, climatology, biogeography and geography of India
- Geophysics, including signal processing, field theory, numerical methods, gravity and magnetic methods, seismology and electrical or electromagnetic methods
- Atmospheric and weather-related topics such as monsoon systems, cyclones, fronts, aviation meteorology and satellite meteorology
- Ocean Sciences, including physical oceanography, tides, currents, estuaries, coastal processes and chemical oceanography
This paper rewards candidates who study topic clusters carefully instead of reading only isolated geology or climate notes.
CSIR NET Life Sciences syllabus 2026
On the official CSIR-HRDG page, Life Sciences is shown through a subject page that includes a syllabus link marked for use up to the exam cycle June 2026. The official Life Sciences syllabus is organized into 13 units.
| Unit | Area |
|---|---|
| 1 | Molecules and their interaction relevant to biology |
| 2 | Cellular organization |
| 3 | Fundamental processes |
| 4 | Cell communication and cell signaling |
| 5 | Developmental biology |
| 6 | System physiology - Plant |
| 7 | System physiology - Animal |
| 8 | Inheritance biology |
| 9 | Diversity of life forms |
| 10 | Ecological principles |
| 11 | Evolution and behavior |
| 12 | Applied biology |
| 13 | Methods in biology |
Within these units, the official syllabus goes into detailed subtopics such as biomolecules, membrane structure, replication and gene expression, signaling, immunology, development, plant and animal physiology, genetics, taxonomy, ecology and lab or analytical methods. Life Sciences candidates should study directly from the official unit structure because many preparation resources rearrange these topics in a confusing order.
CSIR NET Mathematical Sciences syllabus 2026
The official Mathematical Sciences syllabus is divided into four units, and the exam pattern is different from the other subjects because Part C has multiple correct options and no negative marking.
- Unit I: Analysis and Linear Algebra. This includes sets, sequences and series, continuity, integration, metric spaces, vector spaces, matrices, eigenvalues, inner product spaces and quadratic forms.
- Unit II: Complex Analysis, Algebra and Topology. This includes analytic functions, contour integration, residues, groups, rings, fields, Galois theory, and topological concepts such as connectedness and compactness.
- Unit III: ODEs, PDEs, Numerical Analysis, Calculus of Variations, Integral Equations and Classical Mechanics.
- Unit IV: Probability, Statistics, Regression, Sampling, Design of Experiments, Multivariate Analysis, Operations Research, Queueing and Reliability topics.
The official note also indicates that all students are expected to answer questions from Unit I. Candidates from mathematics are expected to answer additional questions from Units II and III, while candidates from statistics are expected to answer additional questions from Unit IV. That is an important instruction for paper selection strategy.
CSIR NET Physical Sciences syllabus 2026
The official Physical Sciences syllabus is split into Part A Core and Part B Advanced. This is a syllabus structure detail, not the same as the exam's question-paper Parts A, B and C.
Core areas:
- Mathematical Methods of Physics
- Classical Mechanics
- Electromagnetic Theory
- Quantum Mechanics
- Thermodynamic and Statistical Physics
- Electronics and Experimental Methods
Advanced areas:
- Advanced Mathematical Methods
- Advanced Classical Mechanics
- Advanced Electromagnetic Theory
- Advanced Quantum Mechanics
- Advanced Thermodynamic and Statistical Physics
- Electronics and Experimental Methods
- Atomic and Molecular Physics
- Condensed Matter Physics
- Nuclear and Particle Physics
The official syllabus moves from core concepts to analytical and application-oriented depth. For Physical Sciences candidates, the biggest mistake is preparing only standard classroom notes without covering the advanced section properly.
