RRB JE Syllabus 2026 – Complete Guide

The Railway Recruitment Board (RRB) conducts the RRB JE Exam to select candidates for Junior Engineer (JE), Depot Material Superintendent (DMS), and Chemical & Metallurgical Assistant (CMA) posts across Indian Railways. The RRB JE 2026 recruitment cycle (CEN 04/2026) has the online application window opened on 14 August 2026. Knowing the RRB JE Syllabus 2026 and exam pattern together is essential before starting preparation, as the exam is conducted in two stages (CBT 1 and CBT 2) that test different subjects and difficulty levels.

RRB JE Syllabus 2026 – Overview

RRB JE Selection Process 2026

Candidates are selected through the following stages, in order:

• First Stage CBT (CBT 1): A screening-level test covering Mathematics, General Intelligence & Reasoning, General Awareness, and General Science. Only candidates who clear CBT 1 (based on RRB's normalization and cut-off process) move to CBT 2.
• Second Stage CBT (CBT 2): A more technical test covering General Awareness, Physics & Chemistry, Basics of Computer Applications, Basics of Environment & Pollution Control, and Technical Abilities specific to the candidate's engineering discipline. Final merit is based on CBT 2 performance.
• Document Verification (DV): Shortlisted candidates, based on CBT 2 merit and category-wise vacancies, are called to verify educational certificates, category certificates, and other documents.
• Medical Examination (ME): Candidates who clear DV undergo a medical fitness test as per the medical standards prescribed for the specific post.

Note: CBT 1 is only a qualifying/screening stage and its marks are not typically counted toward final merit, which is based on CBT 2.

RRB JE CBT 1 Exam Pattern 2026

CBT 1 consists of 100 objective-type MCQs, to be completed in 90 minutes. Each correct answer carries 1 mark, and 1/3 mark is deducted for every wrong answer.

RRB JE CBT 2 Exam Pattern 2026

CBT 2 consists of 150 objective-type MCQs, to be completed in 120 minutes (2 hours), with the same marking scheme of 1 mark per correct answer and 1/3 mark negative marking per wrong answer. Technical Abilities alone accounts for 100 of the 150 marks in CBT 2.

How to Prepare for RRB JE Exam 2026

• Start with the syllabus, not question banks. Map out CBT 1 subjects first since it's the qualifying stage, then move to your specific Technical Abilities branch for CBT 2.
• Build a subject-wise timetable. Since Technical Abilities alone carries 100 of 150 marks in CBT 2, allocate proportionally more study time to your branch subjects than to General Awareness or Computer Basics.
• Use RRB JE previous year question papers (PYQs). This helps you understand question difficulty and recurring topic patterns across CBT 1 and CBT 2.
• Take sectional mock tests as you finish each subject. Don't wait until the full syllabus is done – test topic-wise to catch weak areas early.
• Revise General Science and General Awareness weekly. These sections change least in preparation strategy but need regular touchpoints, unlike technical subjects that need deep, one-time study.
• Practice negative-marking-aware attempts in mocks. With 1/3 mark deducted per wrong answer, build the habit of skipping low-confidence questions during timed practice.
