CSIR-NET 2023 Exam, Eligibility Criteria, Syllabus, Preparation Tips

Joint CSIR UGC NET is a test being conducted to determine the eligibility of Indian nationals for Junior Research Fellowship (JRF) and for Lectureship (LS) /Assistant Professor in Indian universities and colleges subject to fulfilling the eligibility criteria laid down by UGC.

The NTA has announced CSIR UGC NET Eligibility 2023. (National Testing Agency). The CSIR NET 2022 eligibility criteria are determined by NTA based on the age group and educational qualification. To be eligible to apply for the CSIR UGC NET 2023 exam, candidates must have an M.Sc. or equivalent degree/Integrated BS-MS/BS-4 years/BE/B Tech/B Pharma/MBBS with at least 55 percent marks. CSIR NET Practice Papers can be downloaded by candidates who are preparing for the exam.

Candidates should familiarise themselves with the CSIR NET eligibility requirement before applying. If any candidate is determined to be ineligible at a later stage, their application will be immediately denied. The different eligibility criteria needed for CSIR NET 2023 can be found below.


  • The candidate must be a citizen of India.
  • If it is found that a candidate is not qualified, his or her application will be rejected.

CSIR NET Age Restrictions

  • As of January 1, 2022, the maximum age limit for the award of a Joint Research Fellowship (JRF) is 28 years.
  • For reserved category candidates (SC/ST/PwD and female applicants) the upper age limit may be relaxed by up to 5 years, and for OBC – Non-creamy layer candidates by up to 3 years.
  • For the Lectureship, there is no set age limit.

Requirements for CSIR NET Educational Qualifications

  • Candidates must hold a B.Pharma, BE, B. Tech, MSc, MBBS, Integrated BS-MS, or any other science degree with a minimum of 55 percent.
  • Candidates who fall under the reserved category receive a 5% mark reduction.
    This test is also open to those who are studying an M.Sc and have finished their graduation (10+2+3).
  • Candidates who have completed a B.Sc. or are enrolled in an Integrated MS-PhD programme and have received a minimum of 55 percent are eligible to apply.
  • Candidates with a science or engineering background can also apply for the fellowship if they enrol in a Ph.D. or Ph.D. integrated programme within two years after graduation.


The CSIR NET Earth Sciences 2023 examination will be held on January 29, 2023. The CSIR UGC NET Exam Pattern 2023 has been announced by NTA. The exam will consist of 120 questions for 200 points. The question paper is also divided into three sections: A, B, and C. Part A is the same for all courses and will assess candidates’ general aptitude, whilst Parts B and C will contain subject-specific questions. Each part has a variable amount of questions, and the overall number of questions that applicants must attempt varies by subject.

  1. Before beginning their Exam preparation, candidates are encouraged to review the curriculum and exam pattern.
  2. Candidates should attempt to complete a CSIR NET mock test before beginning their preparation to assess their degree of preparedness.
  3. Candidates should plan a route that focuses more on the Candidate’s weak issues and less on the Candidate’s strong topics.
  4. It’s best to start with the fundamentals and work your way up to more advanced topics.
  5. For topics that require continual revision, taking notes is also recommended.
  6. Before beginning a new topic, go over each one again. It would improve the ability to retain information.
  7. Examine past year’s CSIR NET papers to see which questions have been asked more frequently.
  8. Choose the most appropriate study material from a list of Books. There is no need to read all of the books in order to prepare.
