The National Testing Agency (NTA) officially publishes the CSIR NET examination notification and the CSIR NET test pattern. Knowing the intricate aspects of the exam pattern allows students to plan their preparations more effectively. The number of questions in each part and the overall number of questions that candidates must attempt vary for different subjects.
The Human Resource Development Group (HRDG) recently published the updated CSIR NET Chemistry Syllabus on the official website. The exam will consist of 120 questions overall, each worth 200 marks. The exam is further broken down into three sections: A, B, and C. The questions in Parts B and C will be subject-specific, whereas Part A will be common to all disciplines and evaluate candidates’ General Ability.

CSIR NET Chemical Science Exam Pattern
Understanding the exam’s structure, the kinds of questions that will be asked, how long the exam will last, and the scoring system will help candidates prepare more effectively. Inorganic Chemistry, Physical Chemistry, Organic Chemistry, and multidisciplinary topics are the four divisions of the Chemical Sciences syllabus.
Important Points Regarding the Exam Pattern:
- The exam is divided into three parts: Part A, B, and C.
- Each question in Parts A and B is worth two marks. Each question in Part C is worth four marks.
- The total number of multiple-choice questions (MCQs) in the Chemical Science Test is 120.
- The total duration of the exam is 3 hours.
- The negative marking for Parts A and B is 0.5 marks, while the negative marking for Part C is 1 mark.
For a better understanding, the exam format is detailed in the table below:
| Section | Part A | Part B | Part C | Total |
|---|---|---|---|---|
| Number Of Questions | 20 | 40 | 60 | 120 |
| Maximum Marks | 30 | 70 | 100 | 200 |
| Maximum Questions to Attempt | 15 | 35 | 25 | 75 |
| Marks For Each Correct Answer | 2 | 2 | 4 | – |
| Deduction for Each Wrong Answer | 0.5 | 0.5 | 1 | – |
