Exam Structure
The CSIR NET Earth Science exam is a computer-based test (CBT) conducted in two papers:
Paper 1: General Aptitude (200 Marks)
- This paper is common for all subjects and consists of 60 multiple-choice questions (MCQs).
- Each question carries 3.33 marks.
- There is a negative marking of 1 mark for each incorrect answer.
- The duration of the paper is 2 hours.
Paper 2: Earth Sciences (200 Marks)
- This paper is specific to the Earth Sciences subject and consists of 60 MCQs.
- Each question carries 3.33 marks.
- There is a negative marking of 1 mark for each incorrect answer.
- The duration of the paper is 3 hours.
Marking Scheme
The marking scheme for both papers is as follows:
| Type of Question | Marks | Negative Marking |
|---|---|---|
| Correct Answer | 3.33 | 1 |
| Incorrect Answer | 0 | 1 |
| Unattempted Question | 0 | 0 |
