CSIR NET Chemical Science Syllabus 2025, Exam Pattern, Marking Scheme

The CSIR NET Chemical Science Syllabus 2025 is released by the National Testing Agency (NTA) for the candidates who are planning to appear for the CSIR NET exam. The Chemical Science includes various topics as a part of their syllabus; the most important ones include physical Physical Chemistry, Organic and Inorganic Chemistry. Some other interdisciplinary topics include Chemistry in nanoscience and technology, Catalysis and green chemistry, Medicinal chemistry, Supramolecular chemistry and Environmental chemistry.

CSIR NET Chemical Science Syllabus and Exam Pattern 2025

The CSIR UGC NET exam has been scheduled for 28th February, 1st and 2nd March 2025, and the CSIR Chemical Science exam is on 28th February 2025 itself. The Chemical Science Syllabus is divided into three sections: A, B, and C. The Section A is common for all the candidates with subjects like General Science, Quantitative Reasoning & Analysis and Research Aptitude. On the other hand, Section B and C assess the candidate's knowledge in the subjects chosen by them, especially the scientific concepts and their application.

CSIR NET Chemical Science Syllabus 2025 PDF

Here is the direct link to download the CSIR NET Chemical Science Syllabus PDF, which is released by the National Testing Agency (NTA). The main idea behind publishing a well-defined syllabus is to help students prepare better for a particular exam. It helps them limit their preparation and relieves them from the fear of missing out. They can be sure that all that is mentioned in the syllabus will only be asked in the exam and not something beyond it.
