Are you aiming to become a Computer Science Teacher for classes 11-12 under the Bihar Public Service Commission (BPSC)
The BPSC Teacher Recruitment Exam (TRE) 4.0 is your gateway. With a clear understanding of the exam pattern, a strategic approach to the vast syllabus, and the right preparation techniques, you can significantly increase your chances of success.
The exam is divided into three parts.
| Part | Subject / Section | No. of Questions | Total Marks | Nature |
| Part 1 | Language (Hindi / English) | 30 | 30 | Qualifying Only |
| Part 2 | General Studies | 40 | 40 | Scoring |
| Part 3 | Computer Science (Core Subject) | 80 | 80 | High Scoring |
| Total | 150 | 150 | No Negative Marking |
Key Takeaways from the Exam Pattern:
- Total Marks: 150
- Total Questions: 150
- Time Duration: Likely 2.5 to 3 hours (as per standard BPSC patterns).
- No Negative Marking: This is a huge advantage. Attempt every question. Even if you are unsure, an educated guess can work in your favor.
- Part 1 is Qualifying: You need to clear the Language section, but its marks are not added to the final merit. Don’t ignore it, but don’t spend disproportionate time on it either.
