  • Marks: Each question carries 2 marks.
  • Attempt Criteria: Candidates are required to attempt any 15 questions.
  • Scoring: The total marks for this section can be 30 if all 15 questions are answered correctly.
  • Negative Marking: There is a negative marking of 0.5 marks for each incorrect answer.

Part B: Subject-Specific Section

  • Objective: This section tests the candidate’s core subject knowledge in Life Sciences.
  • Number of Questions: Contains 50 questions.
  • Marks: Each question carries 2 marks.
  • Attempt Criteria: Candidates need to attempt any 35 questions.
  • Scoring: The total marks for this section can be 70 if all 35 questions are answered correctly.
  • Negative Marking: There is a negative marking of 0.5 marks for each incorrect answer.

Part C: Advanced Subject-Specific Section

  • Objective: Designed to evaluate the candidate’s in-depth knowledge and application of scientific concepts in Life Sciences.
  • Number of Questions: Contains 75 questions.
  • Marks: Each question carries 4 marks.
  • Attempt Criteria: Candidates are required to attempt any 25 questions.
  • Scoring: The total marks for this section can be 100 if all 25 questions are answered correctly.
  • Negative Marking: There is a negative marking of 1 mark for each incorrect answer.

Total Marks and Duration

  • Total Marks: The cumulative total for the CSIR NET Life Sciences exam is 200 marks.
  • Duration: The exam is conducted over a span of 3 hours without any breaks.

Key Points for Aspirants

  1. Strategic Attempt: Given the negative marking, it’s crucial for candidates to attempt questions judiciously, focusing on accuracy alongside maximizing attempts.
