RRB ALP Selection Process Overview
Before diving into the syllabus, it is essential to understand the stages of the examination. The recruitment process is divided into five key phases:
- First Stage CBT (CBT 1): A screening test to shortlist candidates for the next stage. Marks here are not counted for the final merit.
- Second Stage CBT (CBT 2): The deciding factor for your selection. It has two parts: Part A (Merit) and Part B (Qualifying).
- Computer-Based Aptitude Test (CBAT): Also known as the Psycho Test, mandatory for ALP candidates.
- Document Verification (DV): Verification of original certificates.
- Medical Examination (ME): Candidates must meet the A-1 Medical Standard.
