Important Topics for RRB ALP Exam: Score High and Clear the Cutoff

Do you want to work as a loco pilot in Railways and prepare for the RRB ALP 2026 exam? You might be looking at the huge syllabus and feeling worried. Time is limited, but the truth is, you do not need to read every single page to clear the first stage. The Railway Recruitment Board has a habit of repeating specific types of questions from select chapters. If you study smartly and focus your energy on these highly repeated topics, you can easily clear the CBT 1 cutoff and move to the next round. In this blog, we will break down the most important topics for all subjects to help you save time.

Understand the Exam Pattern of RRB ALP

Before you start studying the topics, you must understand the pattern of the CBT 1 (Computer-Based Test) exam. This is a qualifying stage, meaning its marks will not be added to your final merit list, but you must pass it to write CBT 2. You will get a total of 60 minutes to solve 75 questions. Here is a simple breakdown of the subjects and their marks:

There is a strict negative marking of one-third mark for every wrong answer. Now, let us look at the most important chapters for each subject that will help you cross the safe score.

1. Important Topics for General Science (20 Marks)

For an Assistant Loco Pilot, science is the absolute backbone of the exam. The railway board strictly follows the 9th and 10th standard NCERT syllabus. Do not read heavy engineering books for this section.

• Physics: This is the most important part of science for ALP. Focus heavily on Work, Power and Energy, Speed and Velocity, Mass, Weight and Density, Heat and Temperature, and Basic Electricity. These topics will also help you massively in your CBT 2 exam.
• Chemistry: Memorize the first 30 elements of the Periodic Table. Focus on Acids, Bases and Salts, Chemical Reactions, and everyday chemistry like the formulas for baking soda, washing soda, and bleaching powder.
• Biology: Questions here are very basic. Focus on the human body, human diseases caused by viruses and bacteria, and vitamins (their chemical names and deficiency diseases).

2. Important Topics for General Intelligence and Reasoning (25 Marks)

Reasoning carries the highest weightage in the CBT 1 exam. It is highly scoring, and with good daily practice, you can easily get a full 25 out of 25.

• Coding-Decoding: Memorize the exact number positions of the English alphabet. You will see at least three to four questions from this chapter.
• Statement and Conclusion / Assumption: The railway board loves asking analytical reasoning questions. Read the statement carefully and do not use your outside general knowledge to answer them.
• Number and Alphabet Series: Practice finding the missing number in a series using basic addition, subtraction, or square logic.
• Syllogism: Learn the simple Venn diagram trick to solve these questions without any confusion.
• Venn Diagrams: Finding the logical relationship between three given words using overlapping circles.
• Non-Verbal Reasoning: Questions based on mirror images, paper folding, and counting figures like triangles inside a box.

3. Important Topics for Mathematics (20 Marks)

Do not let calculations scare you. There is no high-level engineering calculus here. It is pure 10th-standard arithmetic. Master these highly repeated chapters:

• BODMAS and Simplification: You will definitely see basic calculation questions. Make sure your addition, multiplication, and division speed is very fast.
• Percentage, Profit and Loss: This is the base of the entire maths section. Learn basic fraction values to solve these questions without writing long steps.
• Time, Speed and Distance: Since you are applying for a train driver job, questions based on trains crossing a platform, pole, or another train are extremely important.
• Time and Work: Questions about how many days a person or a pipe takes to finish a job. Learn the simple LCM method to solve these.
• Basic Mensuration: Just learn the direct formulas for the area and volume of basic shapes like squares, rectangles, cylinders, cones, and spheres.

4. Important Topics for General Awareness (10 Marks)

This section carries the lowest weightage. Please do not waste hours reading deep ancient history or thick geography books. Your return on investment here is very low.

• Current Affairs: Focus only on the news of the last six to eight months. Read specifically about sports awards, science and technology (like ISRO missions), and new CEO or government appointments.
• Static GK: Memorize important books and authors, basic folk dances, and major national parks.
• Basic Polity: Just remember the most important articles of the Constitution and the fundamental rights.

3 Simple Tricks to Clear the Cutoff

1. Focus on Science and Reasoning: Together, these two subjects carry 45 out of 75 marks. If you make these two subjects your core strength, clearing the cutoff becomes a cakewalk.
2. Solve Previous Year Papers: The Railway Board mostly asks the old questions. Solving the previous year’s papers of RRB ALP will give you the exact idea of the question level.
3. Avoid Blind Guessing: Because of the one-third negative marking, guessing is a trap. If you do not know the logic behind a math or reasoning question, leave it immediately and move forward.

You do not need to study the entire day to clear the RRB ALP exam. You just need to be consistent. Stick to these important topics, clear your basic concepts, and give daily mock tests. You will definitely see your name on the CBT 1 qualified list.
