If you are preparing for the RRB ALP 2026 exam, you must know that General Science is the absolute backbone of this paper. Why? Because you are applying for a technical job to drive Indian Railway trains. In CBT 1, General Science carries a solid weightage of 20 marks. The best news is that you do not need to read thick engineering books or tough college-level science. The syllabus is based entirely on your 9th- and 10th-class school books. If you understand the basic concepts, you can easily score a perfect 20 out of 20. In this simple guide, we will tell you exactly how to prepare general science for RRB ALP from absolute zero. Let us make science your highest-scoring subject.
Understand the General Science Syllabus and Weightage
Before you start reading anything, you need to know what the Railway Recruitment Board actually asks. The science section is divided into three parts: Physics, Chemistry, and Life Sciences (Biology). Because this is a Loco Pilot exam, Physics gets the maximum attention. Here is a simple table showing the most important science subjects and how many questions you can expect from them in your CBT 1 exam.
| General Science Subject | Expected Number of Questions | Priority Level |
| Physics | 8 to 10 | Very High |
| Chemistry | 5 to 7 | High |
| Life Sciences (Biology) | 4 to 5 | Medium |
Step-by-Step Preparation Strategy
To master this section, you do not need to study all day. A smart daily reading habit of just one hour is more than enough. Here is how you should plan your preparation step-by-step:
- Make NCERT Your Best Friend: This is the golden rule. Do not buy expensive general knowledge books for science. Just buy the basic NCERT science textbooks for the 9th and 10th standards. Read them line by line like a storybook. The railway board picks questions directly from the exact lines of these books.
- Physics is the Important Section: Give your maximum time to Physics. Clear your basic rules of chapters like Work, Power and Energy, Motion, Sound, Light, and Electricity. Understand the concepts deeply instead of just memorizing them.
- Do Not Fear Numericals: Many students get scared of science math problems (numericals). But RRB ALP asks very simple, direct formula-based questions. If you know the simple formula for Ohm’s Law (V = IR) or the formula for kinetic energy, you will get free marks in just ten seconds.
- Keep Chemistry Simple: For chemistry, you must memorize the first 30 elements of the modern periodic table. Focus heavily on everyday chemistry. Learn the chemical formulas and common names of daily items like baking soda, washing soda, bleaching powder, and plaster of Paris.
- Target Everyday Biology: You do not need to become a doctor. For biology, strictly focus on the human body, the digestive system, and human diseases. Memorize all the vitamins, their chemical names, and the diseases caused by their deficiency.
Common Mistakes You Must Avoid
While practicing general science, make sure you stay away from these common traps that ruin the scores of many hardworking students:
- Reading 11th and 12th Standard Books: This is the biggest mistake. Many students waste months reading high-level physics and chemistry. The official notification clearly states that the syllabus is of the 10th standard (Matriculation) level. Stick to the basics.
- Just Mugging Up Facts: General Science is not history. If you just mug up facts without understanding the reason behind them, the examiner will easily trap you by changing the language of the question slightly. Understand the “why” and “how” behind every scientific rule.
- Ignoring the SI Units: In the exam hall, the options will often have the same numbers but different units. If you do not know that Force is measured in Newtons and Work is measured in Joules, you will click the wrong answer. Always memorize the SI units.
Conclusion
General Science is your ultimate rank booster in the RRB ALP exam. It takes very little time to solve in the exam hall and guarantees solid marks if your basic concepts are clear. Stick to the official NCERT books, practice the previous year’s railway questions regularly, and take your mock tests seriously. You have the true ability to clear this exam easily and wear that railway uniform. Start your daily science reading today.

Frequently Asked Questions (FAQs)
In the CBT 1 exam, the general science section has 20 questions for a total of 20 marks.
The 9th and 10th standard NCERT Science textbooks are the absolute best and most authentic source. After reading them, you can solve the Lucent General Science book for extra multiple-choice question practice.
Yes, simple numerical problems are definitely asked, especially from Physics chapters like Motion, Work and Energy, and Electricity. However, they are strictly basic and formula-based.
Yes, there is a strict negative marking of one-third (1/3) mark for every incorrect answer in the CBT 1 exam. You must avoid blind guessing.
No, deep plant biology is rarely asked. The exam mostly focuses on Zoology, which means the human body, human diseases, and basic cell structures.
