इलेक्ट्रिकल/इलेक्ट्रॉनिक्स शाखा के लिए अतिरिक्त विषयों की एक सूची भी है, जो आपकी तैयारी को और व्यापक बनाती है। इन्हें मुख्य इलेक्ट्रॉनिक्स विषयों के साथ अध्ययन करना चाहिए।
How to Prepare for BEL Probationary Engineer Exam 2026
- Start with your discipline. Part II is 100 of 125 marks. Finish the technical syllabus first, then fit aptitude practice around it.
- Prioritise subjects, not just topics. Use the priority tables below to decide which subjects get the most revision time.
- Practise aptitude in short daily sets. Part I has only 25 marks, so a 30-45 minute daily routine across English, quant, reasoning and general awareness is enough.
- Treat negative marking as part of your strategy. Every wrong answer costs 0.25 mark, so four wrong answers wipe out one correct one. Attempt a question when you can eliminate at least one option with confidence.
- Take full-length mocks in a 2-hour window. With 125 questions in 2 hours, you have under a minute per question on average. Practise moving past questions that stall you.
- Keep a formula and concept sheet for numerical subjects. Control Systems, Thermodynamics, Fluid Mechanics and similar subjects reward quick recall. Revise the sheet regularly and use previous year papers to find your weak areas.
सबसे पहले अपनी शाखा के तकनीकी विषयों की तैयारी करें क्योंकि वे कुल अंक का बड़ा हिस्सा हैं। सामान्य योग्यता के लिए रोजाना थोड़ा समय दें। नकारात्मक अंकन को ध्यान में रखते हुए सोच-समझकर प्रश्न हल करें और समय प्रबंधन के लिए मॉक टेस्ट जरूर दें।
