SSC Scientific Assistant IMD 2026 Exam Pattern
The examination is conducted in two papers: Paper-I and Paper-II, both through Computer-Based Examination (CBE).
Paper-I
For Scientific Assistant in IMD, Paper-I contains:
| Section | Questions | Marks |
|---|---|---|
| General Intelligence & Reasoning | 50 | 50 |
| General Awareness | 50 | 50 |
| Branch Paper | 100 | 100 |
| Total | 200 | 200 |
The duration is 2 hours. Candidates eligible for a scribe receive the applicable extended duration specified in the notification.
Paper-II
Paper-II contains the selected technical subject.
For a CS/IT candidate:
| Section | Questions | Marks |
|---|---|---|
| Branch Paper | 100 | 300 |
| Total | 100 | 300 |
The duration is 2 hours, with the applicable extended duration for eligible candidates.
Is Paper-I Qualifying?
Yes. Paper-I is qualifying in nature.
Candidates who meet the required qualifying criteria in Paper-I are shortlisted for Paper-II. The notification also states that normalized Paper-I marks are used for shortlisting, while normalized Paper-II scores are used for determining final merit.
Therefore, CS/IT students should not completely ignore General Intelligence & Reasoning and General Awareness, even though the technical subject carries substantial weight.
Negative Marking
Both papers consist of objective-type multiple-choice questions.
The notification specifies:
- Paper-I: 0.25 marks deducted for each incorrect answer
- Paper-II: 1 mark deducted for each incorrect answer
The questions are set in Hindi and English.
