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.
