Where is RRB exam going to be conducted? Are there any official centres?

Yes, the Railway Recruitment Board has released the RRB NTPC (UG) result 2025 for the notification CEN 6/2024 on its regional portals. The regions selected the candidates based on their regional vacancies. 

Yes, the syllabus for RRB JE Stage 1 and 2 are different. As Stage 1 CBT focusses on the general subjects including Mathematics, General Science, General Awareness, etc. While in Stage 2 CBT techincal specific subject is asked along with the General Awareness & Science, basics of computer and applications, etc.

RRBs conducts various exams for recruitment to the post of Junior Engineers, Assistant Loco Pilot, Non-technical and popular category, Group, C/Group D, and other posts in departments and offices of Indian railways.

For pattern (aptitude, reasoning, GA) + scale, look at SSC (CGL, CHSL), IBPS (PO/Clerk/RRB), State PSCs, Insurance exams (NIACL, LIC AAO), NRA CET (when active), and DFCCIL/Metro Rail recruitments. If you're eyeing technical RRB JE/SSE, then GATE (for core prep in depth), SSC JE, and state electricity board/PSU junior engineer exams mirror the technical flavour. Build a shared base: Quant, LR, GA (Indian polity, economy, railway basics), and speed tests—then add the technical or job specific layer only where needed.

The recent RRB syllabus differs with the exam (ALP, NTPC, Group D, JE) after that it is same such as: Mathematics, General Intelligence & Reasoning, General Science (Up to 10 th standard CBSE) and General Awareness Current Affairs. Certain subjects under these sections, and other technical topics (in ALP/JE CBT 2) are also dependent upon what RRB exam you intend to add to exam preparation. Always see the notification of your relevant exam.
