RRB JE Syllabus for CBT 2 and Technical Abilities

The RRB JE CBT 2 syllabus shifts the focus from general aptitude to core engineering principles. While the first four sections are common, the "Technical Abilities" part is unique to your diploma or degree.

RRB JE Syllabus for CBT 2 Common Subjects

• General Awareness: Current affairs, Indian geography, culture and history of India, including the freedom struggle, Indian polity and constitution, Indian economy, environmental issues concerning India and the world, sports, and general scientific and technological developments.

• Physics and Chemistry: Standard 10th-level concepts, but applied more towards technical scenarios.

• Computer Applications: Architecture of Computers, Input and Output Devices, Storage Devices, Networking, Operating Systems like Windows and Unix, MS Office, Data Representation, Internet and Email, Websites and Web Browsers, and Computer Viruses.

• Environment and Pollution Control: Basics of the environment, adverse effects of environmental pollution and control strategies, air, water and noise pollution, waste management, global warming, acid rain, and ozone depletion.

RRB JE Syllabus for Technical Abilities (100 Marks)

This subject is the heart of the RRB JE syllabus. You must choose your technical group based on your educational qualification:

1. Civil and Allied Engineering: Engineering Mechanics, Building Materials, Construction of Substructure and Superstructure, Surveying, Drawing, Estimating, Costing and Valuation, Concrete Technology, RCC Structures, Steel Structures, Hydrology and Structures, Highway Engineering, Environmental Engineering.

2. Electrical and Allied Engineering: Basic concepts, circuit law, AC fundamentals, measurement and measuring instruments, electrical machines, fractional kilowatt motors, single-phase induction motors, synchronous machines, generation, transmission and distribution, estimation and utilisation of electrical energy, and basic electronics.

3. Mechanical and Allied Engineering: Engineering Mechanics, Material Science, Strength of Materials, Machining, Welding, Grinding and Finishing Processes, Metrology, Fluid Mechanics & Hydraulic Machinery, Industrial Management, Thermal Engineering.

4. Electronics and Allied Engineering: Electronic Components and Materials, Electronic Devices and Circuits, Digital Electronics, Linear Integrated Circuits, Microprocessors and Microcontrollers, Electronic Measurements, Communication Engineering, Data Communication and Networks, and Computer Programming.

RRB JE Syllabus 2026 Preparation Strategy

To tackle the RRB JE syllabus effectively, you should adopt a dual-phase study plan.

• Phase 1 (CBT 1 Focus): Start with the RRB JE maths syllabus and general science. These sections carry 60% of the weightage in the first stage. Use NCERT books for science and practice speed-math techniques for the arithmetic section.

• Phase 2 (Technical Depth): Once you are confident with the basics, start dedicating 4 hours daily to your technical core subjects. The RRB JE CBT 2 syllabus requires a profound understanding of engineering concepts rather than just rote learning of formulas.

• Mock Tests: To familiarise yourself with the RRB JE exam pattern, take at least two full-length mock tests each week. This helps in managing time, especially for the 100 questions that must be completed within the 90-minute constraint of CBT 1.
