RRB ALP CBT-1

CBT 1 for CEN 01/2026 is scheduled for November 3 to 5, 2026, across 11,127 Assistant Loco Pilot vacancies. If you're reading this now, you're working with roughly five weeks, not the eight-to-twelve-week runway most study plans assume — so this page is built around that  rather than a generic timeline, with relevant preparation insights for RRB NTPC Graduate aspirants as well.

What to Expect in CBT 1

CBT 1 is a 60-minute, 75-question screening test set at Class 10 level. It exists to cut the applicant pool down before the technical CBT 2 stage, and under the revised CEN 01/2026 pattern it now covers only three subjects: Mathematics, General Intelligence & Reasoning, and General Science. General Awareness and Current Affairs, which used to account for a tenth of the paper, has been dropped entirely.

That removal matters more than it sounds like it should. Candidates who prepared for previous ALP cycles built GA revision habits — daily current-affairs reading, static-GK capsules — that no longer earn a single mark here. The three remaining subjects have effectively absorbed that space, which means the paper rewards accuracy and speed in fewer, more concentrated areas rather than broad recall.

Each correct answer earns one mark, and each wrong answer costs a third of a mark. Since RRB runs CBT 1 across multiple shifts with different question sets, raw scores get normalized against your own shift before the merit list is built — so a "safe score" you see floating around forums is only ever a rough guide, not a guarantee.

Domain Breakdown

*RRB has not published an official subject-wise question split for the revised three-subject CEN 01/2026 format. The near-even split above is the working assumption used by most coaching resources, not confirmed RRB data — treat it as a planning estimate, not a fixed row count. The total of 75 questions in 60 minutes is confirmed.

The Section Candidates Consistently Underestimate

General Science is the one that trips people up, and it's rarely because the content is hard — it's because candidates prepare it the wrong way. This section draws directly from Class 9–10 NCERT textbooks: basic physics units, chemical reactions, the human body, plant and animal biology. Anyone who spent the last recruitment cycle memorizing a railway-specific "GS capsule" full of current scientific developments and award-winner trivia is prepping for a paper that no longer exists in this form. The fix is straightforward but requires discipline: work through the actual NCERT chapters rather than a condensed exam-prep summary, because the questions map closely to textbook phrasing.

The second most underestimated area is the reasoning section's statement-conclusion and syllogism questions. These aren't calculation problems — they're built to trap partial logic, and guessing under time pressure has a noticeably worse hit rate here than a rushed arithmetic guess in Mathematics.

How to Use Practice Tests Effectively for CBT 1

Run full 75-question sets under a strict 60-minute clock rather than solving questions in isolation by subject. The binding constraint in CBT 1 isn't difficulty — it's pace. You get roughly 48 seconds per question on average, and a jumbled reasoning series read twice can eat that budget fast.

After each attempt, don't stop at your score. Track which section cost you the most time relative to the marks it returned. Mathematics and Reasoning together make up the bulk of the paper, and they're where speed drills pay off quickest — a candidate who shaves ten seconds off every arithmetic question gains more than one who spends that time chasing a single hard mensuration problem. For General Science, use wrong answers to build a gap list against your Class 9–10 syllabus specifically, rather than treating every miss as "more GS to revise" in the abstract.

Common Mistakes That Lead to a Retake

The most frequent one is still revising General Awareness out of old habit — either from a leftover syllabus PDF or a coaching module that hasn't caught up to CEN 01/2026. Every hour spent there is an hour not spent on Reasoning, which now carries proportionally more weight in a three-subject paper.

The second is attempting Mathematics questions strictly in the order they appear. Candidates who scan first for the quick wins — percentage, simple interest, ratio — and save mensuration or multi-step word problems for a second pass consistently finish with more attempts and fewer careless errors than those who grind through linearly Take a free RRB JE CBT- mock test.

The third is treating unattempted questions as failures to avoid. They cost nothing under this marking scheme; a rushed wrong guess costs a third of a mark. On a paper where the qualifying bar sits at 40% for UR/EWS candidates, 30% for OBC-NCL and SC, and 25% for ST, a handful of avoidable negative marks is often the actual gap between qualifying and not.

RRB ALP CBT  Study Timeline by Starting Point

With CBT 1 only about five weeks out from now, the plan has to be compressed and specific rather than leisurely.

If you're starting close to from scratch: Spend the first three to four days on one untimed diagnostic set to find your weakest of the three subjects honestly. Then run daily short-burst drills — 20 to 30 minutes each on Reasoning and Mathematics — rather than long unfocused sessions, and dedicate alternating days to working through NCERT Class 9–10 Science chapter by chapter. By week three, start layering in full 60-minute timed mocks twice a week.

If you have an ITI or engineering diploma background: Your Mathematics and Science foundations are likely already close to exam level, so front-load Reasoning instead, since it's the section least connected to your technical coursework. Move to full timed mocks by the end of week one, and use the remaining weeks to tighten pace rather than relearn content.

If you're retaking after a previous CBT 1 attempt: Skip the untimed diagnostic — you already know your weak section. Go straight into timed mocks, but review every wrong answer for whether it was a knowledge gap or a pacing error; retake candidates often lose marks to the same time-management issue across attempts rather than to content they haven't learned.

What Changed Most Often on RRB ALP CBT-1 Exam

RRB has revised the ALP selection structure more than once in recent cycles, and CEN 01/2026 carries two changes worth knowing about even though only one directly affects CBT 1. First, General Awareness and Current Affairs was removed from CBT 1's subject list, leaving the three-subject format described above. Second — and this affects CBT 2 and CBAT rather than CBT 1 itself — the final merit weighting shifted to 50% CBT 2 Part A and 50% CBAT, making the psychometric aptitude test carry as much weight as the written technical stage for the first time. It doesn't change how you should prepare for CBT 1, but it's worth knowing that CBT 1 remains purely a screening hurdle with no bearing on final merit, whichever way the later stages are weighted.

Your Next Step

Start with one honest diagnostic to find your weakest section, then move to timed 75-question mocks once that gap has narrowed. CBT 1 isn't a stage where a high margin above cutoff earns you anything — it's discarded the moment you clear it. The goal is a fast, accurate pass that leaves you with energy and weeks in hand for CBT 2's technical trade section, not a maximized CBT 1 score.
