⚡ Detailed Marking Scheme & Negative Marking Rule
Every correct answer fetches 4 marks, while an incorrect response costs 1 mark. For example, guessing 5 questions wrongly will reduce your net score by 5 marks. Therefore, accuracy is crucial. Unanswered questions do not affect your score. The final merit list is prepared on the basis of total marks obtained in Section-I + Section-II + Section-III after meeting sectional and overall qualifying thresholds. In case of a tie, seniority is determined by 60% weightage of DR exam marks + 40% weightage of pre-appointment Phase-I training marks; if still equal, the older candidate (date of birth) gets seniority.

✅ Minimum Qualifying Marks & Merit List Criteria
BSNL has fixed strict cut-offs for each section as well as overall. Without meeting these, candidature is rejected.
| Category | Minimum in Each Section | Overall Minimum (All sections combined) |
|---|---|---|
| UR / OBC (CL) | 40% (80 marks out of 200 per section) For GAT: 32 marks out of 80 | 50% (240 marks out of 480) |
| SC/ST / OBC(NCL) / EWS / PwBD | 35% per section | 45% (216 marks out of 480) |
📌 Important Details: Bond, Training, Probation & Seniority
⏳ Probation Period: 2 years.
🎓 Training Structure: Phase-I (10 weeks) + Field Training (4 weeks) + Phase-II specialization (6 weeks). Trainees receive a stipend.
📊 Seniority Formula: 60% weightage of DR exam marks + 40% weightage of pre-appointment Phase-I training marks. If equal marks, older candidate (by DOB) gets seniority.
📝 Application Process, Fee & Exam Centers
Online applications are accepted via externalexam.bsnl.co.in. Fee: ₹2000 for UR/OBC/EWS, ₹1000 for SC/ST/PwBD. The exam is conducted across 27 major cities (Delhi, Mumbai, Kolkata, Chennai, Bengaluru, Hyderabad, etc.) – candidates can choose one center during registration. Documents required: photograph, signature, 10th certificate, degree mark sheets, caste/PwBD certificate (if applicable), and Photo ID proof.

💡 Preparation Strategy for BSNL JTO (Telecom) Exam
To ace this competitive exam, aspirants should focus on conceptual clarity in core subjects (Analog/Digital Circuits, Communication Systems, Network Theory, Electromagnetic Theory) and solve previous years' BSNL JTO question papers. Since negative marking exists, take sectional mock tests to improve accuracy. For General Ability, stay updated with telecom news (5G, satellite broadband, BSNL revival plans) and revise basic English grammar and history. Time management across 120 questions in 180 minutes (~1.5 minutes per question) is vital.
