RRB JE CBT-1 Mechanical Engineering Syllabus 2026: Subject-Wise Topics & Exam Pattern
The RRB JE CBT-1 Mechanical Engineering Syllabus 2026 helps candidates understand the exam structure and key subjects required for the Railway Recruitment Board Junior Engineer exam. Since the official 2026 notification has not been released yet, the syllabus is based on the previous year’s official pattern for Mechanical & Allied Engineering.
CBT-1 is a common screening test for all engineering branches, meaning Mechanical, Civil, Electrical, and other candidates appear for the same exam. Technical Mechanical Engineering subjects are included only in CBT-2.
Understanding the syllabus in advance helps candidates prepare strategically and focus on high-scoring areas like Mathematics, Reasoning, and General Awareness.
