Frequently Asked Questions

Where can I download the RRB Ministerial and Isolated 2025 question paper PDF?
Every PDF is on this page, free and without login. Each of the 7 posts has its own official answer key book: Chief Law Assistant, Junior Translator (Hindi), Public Prosecutor, Scientific Assistant (Training), Senior Publicity Inspector, Staff & Welfare Inspector and Lab Assistant Grade III (Chemist & Metallurgist). There is also one complete book with every post's paper and a General Ability book common to all posts.
Are these memory-based question papers?
No. Every paper is re-set from the RRB question paper of the exam, with the official correct option ticked in green as per the answer key released on 31 July 2026. No candidate details appear anywhere.
When was the RRB Ministerial and Isolated 2025 exam held?
The CBT for CEN 08/2025 was held on 14 and 15 July 2026 in shifts of 90 minutes (9:00 – 10:30 AM, 12:45 – 2:15 PM and 4:30 – 6:00 PM). The table on this page lists the date and shift of every paper we have.
What is the RRB Ministerial and Isolated 2025 exam pattern and marking?
100 questions of one mark each in 90 minutes: Professional Ability 50 (from the post's own subject) and General Ability 50 (General Awareness, General Intelligence and Reasoning, Basic Arithmetic and General Science). A wrong answer costs one third of a mark.
Why is a post not in my language?
A book can only include what was saved in that language. Every post is in English; Hindi, Bengali, Telugu, Tamil and Marathi books exist where that paper was saved in the language. A question not saved in the book's language is printed in the saved English version and marked with a language chip. Nothing is machine translated.
Is the General Ability part the same for every post?
Posts that sat the same shift got the same 50 General Ability questions; only the 50 Professional Ability questions differ by post. So the General Ability book is good practice for every RRB Ministerial and Isolated candidate, whatever the post.
