General Science: The Group D Differentiator

The **20-question General Science section** is what separates Group D from other Railways exams. This section covers Class 9–10 NCERT-level Science across three domains:

Physics (6–8 Questions)

**Laws of Motion (Newton's Laws):**

• **First Law (Inertia):** An object at rest stays at rest unless acted upon by a net external force. Example: Passengers jerk forward when a bus brakes suddenly.

• **Second Law (F = ma):** Force equals mass times acceleration. The heavier the object, the more force required for the same acceleration.

• **Third Law (Action-Reaction):** Every action has an equal and opposite reaction. Example: A gun recoils when fired.

**Other key Physics topics:**

• Units & Measurements: SI units (meter, kilogram, second, ampere, kelvin)

• Work, Energy & Power: Kinetic energy = ½mv², Potential energy = mgh

• Sound: Reflection of sound (echo), ultrasound applications

• Light: Reflection, refraction, total internal reflection

• Electricity: Ohm's Law (V=IR), series vs. parallel circuits, Joule's Law of Heating

• Magnetism: Electromagnets, magnetic field lines

• Sources of Energy: Renewable vs. non-renewable

Chemistry (6–8 Questions)

**Metals and Non-Metals:**

• Physical properties: Metals are lustrous, malleable, ductile, good conductors

• Non-metals: Brittle (solid), poor conductors (except graphite)

• Reactivity Series: K > Na > Ca > Mg > Al > Zn > Fe > Pb > H > Cu > Au

• Corrosion: Rusting of iron — 4Fe + 3O₂ + 2H₂O → 2Fe₂O₃·H₂O (rust)

**Other key Chemistry topics:**

• Acids, Bases & Salts: pH scale, neutralization reactions

• Carbon Compounds: Hydrocarbons, functional groups, organic chemistry basics

• Periodic Table: Groups, periods, atomic number vs. atomic mass

• Chemical Reactions: Types — combination, decomposition, displacement, double displacement

• Cleaning Agents: Soaps and detergents, emulsification

Biology (5–7 Questions)

**Cell Structure:**

• Cell = basic unit of life; Plant cells have cell wall + chloroplast; Animal cells have centrioles

• Cell organelles: Nucleus (control center), Mitochondria (powerhouse), Ribosome (protein synthesis), Endoplasmic Reticulum

**Disease & Health:**

**Other key Biology topics:**

• Nutrition in plants (photosynthesis: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂)

• Reproduction: Asexual vs. sexual

• Hormones: Insulin (pancreas), Thyroxine (thyroid), Adrenaline (adrenal)

• Nervous System: Brain, spinal cord, reflex arc

• Heredity & Evolution: Mendel's laws

Stage 2: Physical Efficiency Test (PET)

The PET is a **mandatory qualifying round** — candidates who fail PET are eliminated regardless of their CBT score. It is **not scored**; it is purely pass/fail.

PET Standards for Male Candidates

• **35 kg weight lift:** Carry 35 kg for 100 meters in one go, without putting it down — to be done in **2 minutes**

• **1000 meter run:** Complete in **4 minutes 15 seconds**

PET Standards for Female Candidates

• **20 kg weight lift:** Carry 20 kg for 100 meters in one go — to be done in **2 minutes**

• **1000 meter run:** Complete in **5 minutes 40 seconds**

> **Exemptions:** Ex-Servicemen are exempted from PET. PwBD candidates applying for identified suitable posts are also exempted.

How to Prepare for PET Alongside Academic Study

**Running Training (Start 12 weeks before exam):**

• Week 1–3: Brisk walking 2 km daily, transitioning to slow jogging

• Week 4–6: Jog 1 km in under 8 minutes daily

• Week 7–9: Target 1 km in 5 minutes; add interval training

• Week 10–12: Full PET simulation twice weekly; maintain pace and breathing technique

**Weight Carrying Training:**

• Begin with lighter loads (10–15 kg) and gradually build up to 35 kg over 8 weeks

• Practice walking with a balanced load (backpack or sandbag) to develop grip strength and posture

• Strengthen lower back and legs: squats, lunges, deadlifts

**Combined Study + Fitness Schedule:**

---

Stage 3: Document Verification

After PET, shortlisted candidates must submit original documents:

• 10th Marksheet and Certificate (proof of DOB + qualification)

• ITI Certificate (if applicable)

• Caste Certificate (OBC/SC/ST as applicable)

• PWD Certificate (if applicable)

• Aadhar Card, Voter ID, or any government photo ID

• Passport-size photographs

• Ex-Servicemen discharge certificate (if applicable)

Stage 4: Medical Examination

Railway medical standards are strict due to the safety-critical nature of Group D roles:

**Vision Standards:**

• For Track Maintainer, Pointsman: Distant vision 6/9 each eye (without glasses), no color blindness

• For other posts: Distant vision correctable to 6/9 with glasses acceptable

**Hearing Standards:**

• Must not have hearing impairment that affects normal communication

**General Medical:**

• Absence of physical deformities

• No history of major surgeries that affect functional mobility

• Height, chest, and weight within functional norms

> Medical fitness is classified as **A1, A2, A3, B1, B2, C1, C2** based on vision, hearing, and general health. Most Group D posts require at least **B1** classification.

Expert Tips to Maximize Your Score

1. **General Science is your score booster** — 20 marks from 10th NCERT is 100% achievable with 3 weeks of focused reading.

2. **Don't neglect PET timing** — many academically strong candidates fail PET because they underestimate the physical requirements. Start training early.

3. **Negative marking strategy** — skip questions you're less than 60% sure about. Unattempted = 0, wrong = -0.33. Play it smart.

4. **Language choice** — attempt the exam in your most comfortable language to save reading time.

5. **Medical awareness** — if you wear glasses, get your vision checked early. Certain posts require uncorrected vision.

Group D 2026 is the largest employment opportunity in Indian Railways. With disciplined study and physical preparation running in parallel, you can secure your position in one of India's most stable and rewarding public sector careers.
