RRB ALP Important Topics: Preparing for RRB ALP in 2025 means studying smart – not just hard. The Assistant Loco Pilot selection now places heavy emphasis on both general aptitude (CBT-1 and Part A of CBT-2) and trade-specific knowledge (Part B of CBT-2, qualifying in nature). Below is a focused, well-researched guide to the RRB ALP Important Topics you should prioritise for CBT-1 and CBT-2, with concrete topic lists, weightage cues, study tactics and a compact summary you can keep beside your desk.
RRB ALP Exam Structure 2025
Candidates must thoroughly understand the RRB ALP Exam Pattern. Given below are the details:
- CBT-1: Objective screening test covering Mathematics, General Intelligence & Reasoning, General Science (10th standard level) and General Awareness/Current Affairs. ~75 questions, 60 minutes; negative marking 1/3. Qualifying and filters candidates into CBT-2.
- CBT-2: Split into Part A (Mathematics, Reasoning, Basic Science & Engineering / General Science – 100 marks) and Part B (trade/discipline-specific technical questions – qualifying). Part A determines the ranking; Part B is the qualifying round. Time and marks differ by RRB notification; treat Part A as high priority.
RRB ALP Important Topics for CBT-1
CBT-1 is short and selective. Focus on accuracy and speed on these high-yield topics.
Mathematics (Class X level – 20 Qs)
- Number system, HCF/LCM, simplification (BODMAS), percentages, profit & loss, ratio & proportion.
- Time, speed & distance; average; simple & compound interest; basic algebra (linear equations); basic geometry (areas).
Why: Short questions, quick marks — practice mental math and shortcuts.
General Intelligence & Reasoning (25 Qs)
- Series (number & alphabet), coding-decoding, analogy, classification, blood relations, direction & distance, puzzles (basic), syllogism.
Why: Pattern recognition + practice = fast scoring. Focus on common RRB question types.
General Science (10th level – 20 Qs)
- Physics: motion, forces, basic electricity, heat, light.
- Chemistry: acids/bases, metals & non-metals, chemical reactions (common).
- Biology: human physiology, food & nutrition, reproduction, diseases & immunisation.
Why: Straightforward factual Qs — NCERT X/IX level revision is efficient.
General Awareness & Current Affairs (10 Qs)
- Static GK: Indian History, Geography, Polity basics, basic economic terms, Indian Railways (zones, loco types, safety basics).
- Recent events (last 6–12 months): awards, government schemes, important national & international events.
Why: Low volume but often scoring if you keep a weekly current-affairs habit.
RRB ALP Important Topics for CBT-2
Part A of CBT-2 is where ranks are decided – deeper and more numerous questions. Treat it as the main battleground.
Mathematics & Numerical Ability
- Algebra (equations, inequalities), advanced ratio & proportion, time & work, time-speed-distance (including trains problems), geometry (triangles, circles basics), mensuration, permutation/combinations & probability basics.
Study tip: Solve mixed topic sectional mock tests; emphasize accuracy under time pressure.
General Intelligence & Reasoning
- Complex puzzles, multi-dimensional seating, data-sufficiency style reasoning, advanced syllogism, critical reasoning.
Study tip: Practice puzzles daily — adaptability improves faster than raw theory.
Basic Science & Engineering (for Part A)
- Fundamental concepts from Physics & Chemistry applicable to engineering contexts: basic electricity (Ohm’s law, series/parallel), magnetism, power & energy basics, thermodynamics basics, simple machines.
Why: Questions are applied — linking concepts to loco systems helps recall.
RRB ALP Important Topics for CBT-2 (Part B)
Part B differs by educational background/discipline. Typical areas (depending on trade) include:
- Electrical/Electronics: Circuits, semiconductors, measurements, transformers, control systems basics.
- Mechanical/Automobile: IC engines, thermodynamics, manufacturing basics, material science.
- Other trades: discipline-specific fundamental topics as per notification.
Approach: Use past trade papers and the official trade syllabus; make a 2-week intensive revision cycle for Part B because it’s qualifying.
RRB ALP Topic-Wise Weightage
Different topics have different weightage of marks. We have provided the list of topics priority wise for the applicants:
| Priority | Topic area | Why it Matters | Target Study Action |
| 1 | Reasoning (Series, Puzzles) | High question count, fast gains with practice | Daily mixed puzzles + time-bound mocks. |
| 2 | Mathematics (Number system, Algebra, Trains) | Frequent and scoring | Learn shortcuts; 50 drilled problems/day. |
| 3 | Basic Science (10th level + applied) | Moderate weight, easy pick-ups | NCERT X revision + concept maps. |
| 4 | Trade (Part B) | Qualifying; can eliminate you | 2-week technical revision before exam. |
| 5 | General Awareness | Low volume but avoid silly mistakes | Weekly current affairs + static GK checklist. |
RRB ALP Study Plan
It is necessary to design a convenient RRB ALP Study Plan before the exam. Given below are some details:
- First 40 days: Concept clarity (Maths + Reasoning + Science); NCERTs & topic notes.
- Next 20 days: Topic tests + sectional timed mocks; focus on weak topics.
- Last 10–15 days: Full mocks (simulate CBT timing), Part B brush-up (if applicable), revision notes & error log.
Daily micro-tasks: 30 min current affairs, 1 hour puzzles, 1 hour maths, 30–45 min science/technical.
Summary of RRB ALP Important Topics
The summary of RRB ALP important topics are given below. Check out the details for a quick overview:
| Section | Key Focus Area | Priority Level | Preparation Tips |
| Mathematics (CBT-1 & 2) | Number System, HCF & LCM, Percentages, Time-Speed-Distance, Time & Work, Profit & Loss, Algebra, Mensuration | ⭐⭐⭐⭐ | Practice 40–50 problems daily; note key formulas; focus on speed & accuracy. |
