Exam Pattern
The BSNL JTO 2026 Computer-Based Test consists of three sections with a total of 120 objective-type multiple-choice questions carrying 480 marks, to be completed in 3 hours. The question paper is in English.
| Section | No. of Questions | Marks |
| Section I - Engineering Stream I | 50 | 200 |
| Section II - Engineering Stream II | 50 | 200 |
| Section III - General Ability Test | 20 | 80 |
| Total | 120 | 480 |
Marking Scheme
Each correct answer: +4 marks
Each wrong answer: minus 1 mark (negative marking)
Unattempted questions: no marks awarded, no penalty
No separate sectional time limit - the 3-hour duration applies to the whole paper
Minimum Qualifying Marks
Unreserved and OBC (Creamy Layer): 40% in each section AND 50% overall
SC / ST / OBC (Non-Creamy Layer) / PwBD / EWS: 35% in each section AND 45% overall
Candidates must clear both the sectional cut-off and the aggregate cut-off to be considered for the final merit list - meeting only one is not sufficient.
