RRB CBT 1

RRB CBT 1 is the first-stage computer-based screening test used in multiple Railway recruitment drives. It is designed to shortlist candidates for the next stage of selection for posts such as NTPC, Group D, Assistant Loco Pilot (ALP), and Junior Engineer (JE). Since Railway recruitment attracts a very large number of applicants across India, CBT 1 is used to test core aptitude, general awareness, reasoning, and basic science or mathematics knowledge depending on the post.

RRB CBT 1 is commonly used as the first screening stage for:

• NTPC — clerical and commercial posts, station-related posts, and similar non-technical roles
