RRB JE Exam Pattern (Last-Cycle Basis)

CBT 1 (Screening)

Section	Questions (indicative)	Marks (indicative)	Duration	Negative Marking
Mathematics	30	30	Shared	Yes (verify deduction value)
General Intelligence and Reasoning	25	25	Shared	Yes
General Awareness	15	15	Shared	Yes
General Science	30	30	Shared	Yes
Total	100	100	Commonly 90 minutes

Key rules for CBT 1:

• CBT 1 is a screening stage; the score typically does not carry to final merit.
• Questions are at diploma-level engineering difficulty.
• General Science carries notable weight (30 questions) and should not be underweighted in preparation.

CBT 2 (Decisive)

Section	Questions (indicative)	Marks (indicative)	Duration	Negative Marking
General Awareness	15	15	Shared	Yes
Physics and Chemistry	15	15	Shared	Yes
Basics of Computers and Applications	10	10	Shared	Yes
Basics of Environment and Pollution Control	10	10	Shared	Yes
Technical Abilities (your discipline)	100	100	Shared	Yes
Total	150	150	Commonly 120 minutes

Key rules for CBT 2:

• The Technical Abilities section carries the most weight and is the primary merit-deciding factor.
• All sections are objective, marked out of 1 mark per question on a last-cycle basis.
• Confirm the exact section split, marks, and duration in the official notice.
• There is no qualifying sub-section in CBT 2 in the usual format; the full CBT 2 score decides merit.

Phase-Wise Preparation Strategy with Resources

Phase 1: Technical Discipline Foundation (Months 1 to 2)

Focus: Deep preparation of your engineering discipline for CBT 2 Technical Abilities

This is the most important phase for RRB JE. Technical Abilities carries 100 out of 150 marks in CBT 2 and is the merit-deciding section. Begin here, not with the common sections.

Discipline	Recommended Resources
Civil	R.K. Bansal (Fluid Mechanics), B.C. Punmia (Surveying, RCC), IS codes basics
Mechanical	R.K. Bansal (Fluid Mechanics, Thermodynamics), V.B. Bhandari (Machine Design), R.S. Khurmi (Theory of Machines)
Electrical	I.J. Nagrath and D.P. Kothari (Power Systems and Machines), C.L. Wadhwa (Electrical Technology)
Electronics	Boylestad (Electronic Devices), Morris Mano (Digital Electronics), Haykin (Communication Systems)

Daily hours: 5 to 6 on technical subjects.

Phase 2: Common CBT 1 Sections (Month 3)

Focus: Mathematics, reasoning, general science

• Work through NCERT Class 9-10 Science once for General Science.
• Revise diploma-level Maths: trigonometry, mensuration, algebra.
• Drill reasoning patterns for 30 minutes daily.
• Begin current affairs tracking with a monthly digest.

Daily hours: 5 to 6.

Phase 3: CBT 1 Mock Practice (Month 4)

Focus: Full CBT 1 mocks twice a week

Take at least 2 full CBT 1 mocks per week under the 90-minute constraint. Analyse section-wise accuracy. Weak topics identified should be addressed within 48 hours of each mock.

Daily hours: 6 to 7. Split between mock review and continued technical preparation.

Phase 4: CBT 2 Technical Intensive (Post-CBT 1 Result)

Focus: Technical Abilities mastery, CBT 2 common sections

Shift full intensity to CBT 2 preparation after the CBT 1 result. Focus on:

• Topic-by-topic revision of your engineering discipline
• Numerical problem practice for technical topics
• CBT 2 common sections: computers, environment, physics and chemistry
• Full CBT 2 mock tests at least twice a week

Daily hours: 6 to 7.

Common Reasons Candidates Lose the Cycle

• Treating CBT 2 Technical Abilities lightly. It carries 100 out of 150 marks in CBT 2 and decides merit. Candidates who treat it as a secondary concern consistently underperform.
• Wrong post-group application. A qualification mismatch between your degree or diploma and the post group causes rejection at document verification, wasting the entire attempt.
• Underweighting General Science in CBT 1. It carries 30 questions out of 100, more than General Awareness. Candidates who skip it lose the CBT 1 screening.
• Insufficient numerical practice for technical topics. Technical Abilities questions are largely numerical; formula knowledge alone is not enough without calculation practice.
• Planning against tentative dates. Confirm dates on the official railway recruitment portal before making study leave or financial commitments.
