RRB NTPC General Science Mock Test 2026: Physics, Chemistry and Biology MCQs
This full-length subject-wise test combines 60 original Class 10-level Science questions with a 45-minute custom timer, one-third negative marking, Mark for Review, detailed concept explanations, a question palette and chapter-wise score analysis.
General Science is a part of the broader General Awareness preparation for RRB NTPC. It can save valuable time in the exam because many questions are direct, but it becomes difficult when a familiar concept is asked through a daily-life situation. A student may remember that force is measured in newtons but still make a mistake when the same idea is used in a short numerical question.
This RRB NTPC General Science Mock Test 2026 is designed to test more than one-line memory. Physics questions check units, motion, force, heat, sound, light and electricity. Chemistry questions check matter, atoms, reactions, acids, metals and common compounds. Biology questions check cells, human systems, diseases, vitamins, plants and ecology.
Class 10-level basics are usually more useful than collecting advanced notes. The better approach is to understand one concept, solve MCQs, read the solution and record the mistake. After submission, this test separates your Physics, Chemistry and Biology performance so you can revise the subject that is actually lowering your score.
Official information checked on 15 July 2026: The latest applicable NTPC recruitment cycle includes CEN 06/2025 for Graduate posts and CEN 07/2025 for Undergraduate posts. CBT-1 has an indicative 100 questions in 90 minutes—40 General Awareness, 30 Mathematics and 30 General Intelligence and Reasoning. CBT-2 has an indicative 120 questions in 90 minutes—50 General Awareness, 35 Mathematics and 35 Reasoning. One-third of the marks assigned to a question is deducted for a wrong answer. The General Awareness syllabus includes General Science and Life Science up to Class 10 CBSE level. Check the official RRB NTPC Graduate notice page.
Custom-test note: This is a custom subject-wise practice test. In the actual RRB NTPC examination, General Science questions are attempted within the combined General Awareness and CBT time limit. These are original exam-style practice questions created for self-study and are not copied from an official previous-year paper.
Why General Science Is Scoring but Still Tricky
- Many questions are based on school-level facts and concepts.
- Most answers require less calculation than Mathematics.
- Units, formulas, organs and common chemicals can be revised repeatedly.
- A well-revised science question can often be answered within seconds.
- Similar terms such as speed and velocity or arteries and veins are mixed up.
- Students remember formulas but forget units or the meaning of variables.
- Chemical names, formulas, vitamins and hormones look similar during revision.
- Blind guessing becomes costly because of negative marking.
Knowing that sound needs a medium is factual recall. Understanding why it cannot travel through a vacuum is concept clarity. Remembering that acids turn blue litmus red is a fact, while understanding the role of hydrogen ions gives better clarity. In Biology, knowing that kidneys filter blood is basic recall; understanding the nephron explains how urine formation actually happens.

What This Test Actually Measures
1. Factual Recall
Can you remember a unit, organ, formula or chemical name without confusing it with a similar fact?
2. Concept Clarity
Can you explain why a passenger moves forward when a bus suddenly stops or why sound cannot move through vacuum?
3. Daily-Life Application
Can you connect pressure, heat transfer, cleaning action or digestion with situations you see around you?
4. Similar-Term Clarity
Can you separate acids from bases, arteries from veins, xylem from phloem and mass from weight?
5. Revision Strength
Can you recall the concept several days after studying it instead of remembering it only during the first reading?

How to Build a Science Error Log
A science error log converts a wrong answer into a revision task. Create six columns: question or chapter, subject, error type, correct concept, formula or fact to remember, and next revision date.
Concept not studied
Return to the chapter and learn the foundation before solving more MCQs.
Formula forgotten
Add it to a one-page formula sheet and revise it for a few minutes daily.
Unit mistake
Maintain a separate SI-unit table and write units in every numerical step.
Similar terms confused
Create a two-column comparison such as xylem vs phloem or speed vs velocity.
Calculation or reading mistake
Write the given values first and underline what the question actually asks.
Blind guess
Attempt only when you can recall the concept or eliminate options with a clear reason.

Common Mistakes in RRB NTPC General Science Preparation
Starting with advanced Science
Complete Class 10-level basics before using advanced competitive-exam notes.
Memorising without understanding
Ask why the statement is true and connect it with a process or daily-life example.
Ignoring SI units
Learn every important quantity with its formula, unit and symbol.
Skipping diagrams
Use simple diagrams for mirrors, lenses, circuits, cells and body systems.
Mixing Biology terms
Create comparison tables for arteries and veins, hormones and glands, or xylem and phloem.
Learning formulas without uses
Study a chemical name, formula, common use and property together.
Ignoring Physics numericals
Practise small calculations involving speed, force, power, current and resistance.
Studying only Biology
Keep a weekly balance among Physics, Chemistry and Biology.
Not revising wrong answers
Reattempt the concept with a fresh question instead of memorising the correct option.
Guessing despite negative marking
Guess only after meaningful elimination, not because one option looks familiar.
Using too many sources
Choose one main source and use MCQs for testing rather than collecting material.
Checking only the final score
Study subject accuracy, chapter mistakes and the reason behind each wrong answer.
