Preparing for the Railway Recruitment Board (RRB) Junior Engineer examination requires a strategic approach built upon a clear understanding of the syllabus and exam structure. The RRB JE 2026 exam is conducted in two primary stages: CBT 1 and CBT 2. Each stage serves a distinct purpose, combining non-technical aptitude, general science, and domain-specific engineering subjects.
Overview of RRB JE CBT 1 and CBT 2 Exam Patterns
Knowing the weightage, question distribution, and marking scheme is crucial for effective time management during preparation. Both stages feature a negative marking of 1/3 mark for every wrong answer.
