How to Prepare for RRB JE Exam 2026: Subject-wise Study Strategy
Since Technical Abilities alone carries 100 of the 150 marks in CBT-II, and CBT-I only decides your CBT-II eligibility (not your final merit), your technical subject mastery is the single biggest lever for improving your final Merit Index and rank.
| Section | Weightage | Preparation Focus |
|---|---|---|
| CBT-I: Mathematics | 30 marks | Master fundamentals — practice speed & accuracy for time-bound problem solving |
| CBT-I: Reasoning | 25 marks | Focus on pattern recognition — analogies, series, coding-decoding are high-frequency |
| CBT-I: General Awareness | 15 marks | Daily current affairs + static GK revision |
| CBT-I: General Science | 30 marks | NCERT Class 9–10 Physics, Chemistry, Biology — a high-scoring, low-effort section if revised well |
| CBT-II: Technical Abilities | 100 marks | The single biggest scoring opportunity — prioritize this above all else once CBT-I is cleared |
| CBT-II: General Awareness, Physics-Chemistry, Computers, Environment | 50 marks combined | Common to all candidates — a strong, disciplined revision here boosts your overall CBT-II score significantly |
