RRB JE CBT-1 Civil Engineering Syllabus 2026: Subject-Wise Topics & Exam Pattern
The RRB JE CBT-1 Civil Engineering Syllabus 2026 helps candidates understand the subjects and topics they need to prepare for the Railway Recruitment Board Junior Engineer examination. Since the official 2026 notification has not been released yet, candidates should refer to the syllabus prescribed in the previous notification.
While CBT-1 includes subjects such as Mathematics, General Intelligence & Reasoning, General Awareness, and General Science, Civil Engineering technical subjects are tested only in CBT-2.
Understanding the syllabus before starting your preparation will help you plan your studies more effectively and revise important topics in a structured manner.
RRB JE CBT-1 Exam Pattern 2026
Before studying the syllabus, it is important to understand the CBT-1 exam pattern.
CBT-1 consists of 100 objective-type questions and must be completed in 90 minutes. Candidates eligible for a scribe are given 120 minutes. The test carries 100 marks in total.
The CBT-1 question paper is divided into the following sections:
-
Mathematics – 30 questions
-
General Intelligence and Reasoning – 25 questions
-
General Awareness – 15 questions
-
General Science – 30 questions
There is a negative marking of one-third of the marks allotted for each wrong answer. The minimum qualifying marks are 40% for UR/EWS candidates, 30% for OBC (NCL) and SC candidates, and 25% for ST candidates.
RRB JE CBT-1 Civil Engineering Syllabus 2026
The RRB JE CBT-1 is a common examination for all engineering streams, meaning every candidate, regardless of their engineering branch, including Civil, Mechanical, Electrical, or Electronics, will face the same syllabus in CBT-1.
So Civil Engineering aspirants targeting RRB JE 2026 must prepare the same CBT-1 syllabus as candidates from other streams. This first stage is purely a screening test and does not include any branch-specific or Civil Engineering technical topics, which are tested only in CBT-2.
