PSU GATE Cutoff for OBC category typically sees 4-10 marks lower than that of general category candidates. Even if it is lower than the general category, they typically need 65-70 marks to get shortlisted at top PSUs like DRDO, PGCIL, and IOCL.
- Computer Science typically has the highest cutoff, around 70-72 marks for OBC candidates in IOCL.
- DRDO usually has the highest cutoff marks across all branches for OBC candidates. For example, 75-76 marks for Civil, and 71-74 marks for Mechanical branches.
- Civil Engineering at PGCIL required almost 70 marks for OBC candidates to get shortlisted.

Key Summary
- For the premier Public Sector Undertakings (PSUs) such as DRDO, PGCIL, and IOCL, a score in the range of 65 to 70 is generally required, though this can vary by branches.
- OBC candidates often receive a small relaxation in cutoff marks relative to the general category candidates.
- Mechanical and Civil Engineering branches at DRDO tends to have highest cutoffs with frequently exceeding 71-76 marks out of 100.
IOCL PSU GATE Cutoff For OBC Category
The cutoff for OBC in IOCL is very competitive, but lower than that for the general category. In recent years, OBC candidates need around 35-50 marks to be shortlisted.
- Computer Science at GATE 2024 had the highest cutoff for OBC students, around 70 marks out of 100.
- Candidates in the ECE and Civil branches can expect a 43-45 mark cutoff for OBC students.
- If your GATE score crosses the PSU GATE cutoff for OBC, you have a strong chance for the Trainee Engineer post at IOCL.
| GATE Branches/Discipline | Expected GATE cutoff for OBC |
|---|---|
| Mechanical | 35-40 |
| Electrical | 35-38 |
| Civil | 43-45 |
| Electronics & Communication | 43-45 |
| Computer Science | 70-72 |

Ques. Do I have a chance at IOCL with 68 marks in CSE as an OBC candidate?
Ans. 68 marks can be borderline, especially for CSE. Typically, the cutoff for CSE at IOCL ranges from 69 to 72.
PGCIL PSU GATE Cutoff For OBC Category
PGCIL recruits for transmission power grid roles, especially in Electrical, Civil, and Electronics branches. The PSU GATE cutoff for OBC is slightly relaxed, around 4-10 marks lower than the general category.
- The civil branch usually sees the highest cutoff for OBC, which we can expect around 67-70 marks in GATE 2026.
- If you have a score of 57-60 marks in CSE GATE, you have a chance of getting shortlisted for further interviews at PGCIL.
