FAQs
The RRB JE IT Syllabus for 2026 largely follows the same core structure as previous cycles. However, candidates should expect greater emphasis on practical IT concepts such as Operating Systems, DBMS, Networking, and Software Engineering, along with updated questions reflecting current technologies and digital railway systems.
In CBT-2, the most high-scoring and frequently asked subjects are:
Data Structures & Programming (C/C++/Java)
Operating Systems (Unix/Linux fundamentals)
Database Management Systems (SQL, Normalisation)
Computer Networks (OSI, TCP/IP, Protocols)
Yes, basic to intermediate coding knowledge is essential. While the exam does not involve writing long programs, candidates must understand:
Logic building
Flow of programs
Output-based questions
Algorithms and data structures
Even IT candidates must clear CBT-1 to qualify for CBT-2, so at least 30–35% of total preparation time should be dedicated to CBT-1 subjects like Mathematics, Reasoning, General Awareness, and General Science.
The most effective approach is:
Phase-wise preparation (CBT-1 basics → CBT-2 technical depth)
Topic-wise study aligned with the official syllabus
Regular mock tests and previous year question practice
Weekly revision of technical subjects
