How to Calculate Your Score Using the RRB ALP CBT 1 Answer Key
Every candidate must calculate their expected score before deciding whether to raise an objection. The tentative score in the RRB ALP CBT 1 exam is calculated as: 1 × Number of Correct Responses minus ⅓ × Number of Incorrect Responses. This means negative marking of 1/3rd mark applies for every wrong answer. For example, if a candidate has 70 attempted answers out of which 10 are wrong, the score will be: (60 × 1) – (10 × 0.25) = 60 – 2.5 = 57.5 marks.
The minimum qualifying marks for CBT 1 are: UR/EWS – 40%, OBC – 30%, SC – 30%, and ST – 25%. CBT 1 is only a screening stage — its marks are not counted in the final merit. The final merit is calculated using 70% weightage from CBT 2 Part A and 30% weightage from the CBAT (Aptitude Test). Candidates must simply clear the CBT 1 cutoff to qualify for CBT 2.
How to Raise Objections Against RRB ALP Answer Key 2026
Candidates can challenge the provisional RRB ALP answer key. The objection facility has been made available from 20th to 26th March 2026 (up to 5 PM), and no challenges are accepted after the deadline. To raise an objection, log in to your regional RRB portal, click “Challenge Answer Key,” select the disputed question, and upload valid supporting proof such as a reference from an NCERT textbook or official publication. The fee to challenge a question is ₹50 per question plus applicable bank charges. This fee is refundable if the objection is accepted.
Payment can be made via RuPay Debit Card, SBI VISA/Master Debit Card, Net Banking, or UPI. Only strong, evidence-backed objections should be submitted — frivolous challenges waste the ₹50 fee. After the objection window closes, RRB will review all submissions and release the final answer key in April 2026, followed by the CBT 1 result.
RRB ALP Selection Process – Full Overview
The RRB ALP 2026 selection process involves five major stages: CBT 1 (Screening) — objective type test to shortlist candidates. CBT 2 (Merit) — consists of Part A covering Maths, Reasoning, and Science, and Part B covering the Relevant Trade. CBAT (Psycho Test) — mandatory for ALP posts to check cognitive abilities with no negative marking. Document Verification — authentication of educational and category certificates. Medical Examination — strict vision standards (A1 Category) required for Loco Pilots.
CBT 2 is the most critical stage as it determines the final merit. Part A covers Mathematics, General Intelligence and Reasoning, Basic Science and Engineering, and General Awareness. Part B is trade-specific and tests knowledge in the candidate’s chosen trade subject. Candidates who qualify CBT 1 should immediately begin intensive preparation for CBT 2 without waiting for the result.
