- To appear for Life Sciences, your degree must relate to biological sciences.
2. Age Limit for CSIR NET
✔ For JRF (Junior Research Fellowship)
- Maximum age: 28 years
- Age relaxation:
- +5 years for SC/ST/PwD
- +3 years for OBC (Non-Creamy Layer)
✔ For Assistant Professor / Lectureship
- No upper age limit
This means candidates of any age can apply for the Lectureship category.
CSIR NET Exam Pattern (Latest and Updated)
The CSIR NET exam consists of a single paper for each subject, conducted for 3 hours in online CBT mode. The question paper consists of Multiple Choice Questions (MCQs) divided into three parts:
CSIR NET Question Paper Pattern
✔ Part A – General Aptitude
Common for all subjects.
Includes:
- Quantitative reasoning
- Logical reasoning
- Numerical aptitude
- Graph interpretation
- Data analysis
This section tests analytical and problem-solving skills.
✔ Part B – Subject Knowledge (Moderate Level)
This section includes subject-related conventional MCQs testing basic and intermediate-level concepts.
✔ Part C – Advanced Subject Knowledge
This is the most important part of the exam and tests:
- High-level conceptual understanding
- Scientific reasoning
- Research-oriented problem-solving
- Analytical thinking
Part C has higher weightage and is designed to evaluate research aptitude, making the exam suitable for scientific research roles.
CSIR NET Subject-Wise Marks Distribution
Although marks distribution varies slightly by subject, a common pattern is:
- Total Marks: 200
- Total Time: 180 minutes
- Negative Marking: Yes (varies by section)
Each subject has a different number of questions you can attempt, but overall marking scales remain consistent.
