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. This is consistent with the pattern description in the reference sources; candidates should confirm the exact merit-weightage rule in the official notification.

RRB JE Exam Pattern 2026
RRB JE CBT 1 Exam Pattern
| Subject | No. of Questions | Marks |
|---|---|---|
| Mathematics | 30 | 30 |
| General Intelligence & Reasoning | 25 | 25 |
| General Awareness | 15 | 15 |
| General Science | 30 | 30 |
| Total | 100 | 100 |
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
| Subject | No. of Questions | Marks |
|---|---|---|
| General Awareness | 15 | 15 |
| Physics & Chemistry | 15 | 15 |
| Basics of Computer Applications | 10 | 10 |
| Basics of Environment & Pollution Control | 10 | 10 |
| Technical Abilities (branch-specific) | 100 | 100 |

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. Since Technical Abilities alone accounts for 100 of the 150 marks in CBT 2, it carries the largest share of this stage this is a direct read of the marks distribution above, not a separate weightage claim from any source.

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.
