Part I: 

The first part of the CSIR Physical Science comprises 20 questions. These questions are usually asked from topics like Quantitative Reasoning, General Science, Analysis and Research Aptitude. Out of the 20 questions, the candidates are required to answer any of the 15 questions, whichever they deem scoring. Each question in part I of the paper carries two marks. Therefore, the total marks in this section is 30 out of 200. 

Part II

The second part of the Physical Science exam consists of 25 questions. These 25 questions are set in the form of Multiple Choice Questions or MCQs. The questions are mainly asked from the topics which are covered in Part I or Core part of the CSIR NET Physical Science syllabus. Each question carries 3.5 Marks and the total marks in the section will be 70 out of 200. A candidate must answer 20 questions out of the 25 questions. 

Part III

The third part of the Physical Science exam comprises a total of 30 questions out of which a candidate must answer any 20 questions. The questions in the third part are based on Part II and Part I which are specifically curated to gauge the scientific knowledge and concepts of the students. It is mostly based on using the practical knowledge derived from the theoretical knowledge in the first place. Each question in this section carries 5 marks and the total score in this section is 100 out of 200.

Candidates must note that there will be a negative marking of 25% of the total score for each wrong answer. 

Important Tips For CSIR NET Physical Science Exam: 

  • Part I questions will be common for all the subjects included under Science and Technology. Questions are mostly asked from logical reasoning, scientific quizzes, puzzles, etc. 
  • The second part of the CSIR UGC NET exam comprises subject-related multiple-choice questions. 
  • There are only a limited number of questions to be answered in every set. If a candidate exceeds the number, only the first set of the asked number of questions will be verified.
