Frequently asked questions
Is this an official RRB question paper?
No. It is an independent practice mock containing original questions mapped to the official RRB Junior Engineer / DMS / CMA CBT-I syllabus and pattern.
Is there a separate timer for each CBT-I section?
No. RRB JE CBT-I uses a single 90-minute timer for all four sections combined, with no sectional lock — you can move between Mathematics, General Intelligence and Reasoning, General Awareness, and General Science questions freely.
Does CBT-I decide the final RRB JE merit list?
No. CBT-I is a common screening test used to shortlist candidates for CBT-II, which is discipline/branch-specific. The final merit is based on CBT-II, followed by Document Verification and a Medical Examination.
Is there negative marking?
Yes. A correct answer earns 1 mark, and a wrong answer deducts one-third (0.333) of a mark. Unattempted questions score zero.
Do I need an account to attempt the mock?
No. You can start immediately without signing up, and the result is stored only on your current device.
