Indian Railways conducts the Junior Engineer exam to recruit technical supervisors for its civil, mechanical, electrical, and signal departments. This is a great opportunity for engineering diploma and degree holders. The exam has two computer-based tests. CBT 1 is a general screening test covering Math, Reasoning, Science, and GK. CBT 2 is the core test. It focuses on your specific engineering branch and basic computer concepts. Clearing RRB JE requires strong command over technical formulas and quick calculation speed. Most candidates spend around six to nine months of dedicated study. Our tracker below lists all general topics and technical sections to help you structure your revision. You can mark your progress offline as you complete each topic.
