General Science un sections mein se hai jahan sabse kam mehnat mein sabse zyada marks milte hain — badi shart yeh hai ki aap sahi jagah se padhein. RRB Group D mein iske 25 question hote hain, SSC aur police bharti mein General Awareness ka bada hissa Science se aata hai.
Aur sabse achhi baat: General Science ki taiyari ke liye aapko koi mehngi book nahi chahiye. NCERT Class 6 se 10 tak ki Science ki kitaabein, jo officially free download hoti hain, lagbhag poora kaam kar deti hain.
Physics: Sabse Zyada Poochhe Jaane Wale Topics
- Gati aur bal — Newton ke teen niyam aur unke rozmarra ke udaharan
- Kaam, urja aur shakti — urja ke roop aur unka rupantaran
- Prakash — paravartan, apvartan, lens aur darpan, aankh ke dosh (myopia, hypermetropia)
- Dhwani — taranga, aavritti, ultrasound ke upyog
- Vidyut — Ohm ka niyam, series aur parallel, fuse aur earthing
- Chumbakatva — chumbakiya kshetra aur vidyut chumbak
- Ushma — taapman ke paimane, ushma ka sanchalan
- SI units — kaun si rashi ka kaun sa matrak, aur maapak yantra
SI units aur measuring instruments — yeh do chhote topics hain lekin inse lagbhag har exam mein ek-do question pakka aata hai. Inki ek table banakar rakhiye.
Chemistry: Yaad Rakhne Wale Hisse
- Padarth ki avasthayein aur unke parivartan
- Parmanu aur anu — parmanu ki sanrachna, isotopes
- Aml, kshaar aur lavan — pH scale aur rozmarra ke udaharan
- Dhatu aur adhatu — gun, reactivity series, alloy aur unke ghatak
- Carbon compounds — hydrocarbon, saban aur detergent
- Common naam aur chemical formula — jaise baking soda, washing soda, common salt, quick lime, blue vitriol
- Gases — unke gun aur upyog
Chemistry mein sabse zyada question common naam aur chemical formula se aate hain. Yeh purely yaad karne wali cheez hai — ek table banaiye aur roz 5 minute dekhiye. Yeh 10 din mein pakka ho jaata hai.
Biology: Sabse Zyada Scoring
| Topic | Kya Yaad Rakhna Hai |
|---|---|
| Koshika | Cell ke ang aur unke kaam — khaas kar mitochondria, ribosome, chloroplast |
| Manav sharir | Pachan, shwasan, rakt parisancharan, tantrika tantra ke mukhya ang |
| Vitamins | Har vitamin ka scientific naam, uska srot, aur uski kami se hone wala rog |
| Rog | Kaun sa rog virus se, kaun sa bacteria se, kaun sa protozoa se; vaahak keet |
| Grandhiyan | Pramukh endocrine glands aur unke hormone |
| Paudhe | Pravaka-sanshleshan, paudhon ke hormone, vargikaran |
Biology mein sabse zyada return “vitamins ki kami se hone wale rog” aur “rog aur unke karan” se milta hai. Inki ek table bana lijiye — do page mein poora topic aa jaata hai.
Padhne Ka Sahi Tareeka
- NCERT Class 6 se 8 tez padhiye — yeh basic hai, ek-do hafte kaafi hain.
- Class 9 aur 10 dhyan se padhiye — yahin se sabse zyada question aate hain.
- Har chapter ke baad table banaiye — paragraph mein notes revise nahi hote, table hote hain.
- Previous year questions lagaiye — isse pata chalta hai ki kis depth tak poochha jaata hai.
- Roz 15 minute revision — Science mein bhoolne ki dar zyada hoti hai.
Ek zaroori baat — competitive exams mein Science ke question numerical nahi hote, factual hote hain. Aapko formula lagakar hisaab nahi karna, sirf yeh yaad rakhna hai ki kaun si cheez kya karti hai. Isliye Physics ke chapters bhi ratne wale nazariye se padhiye, solve karne wale nazariye se nahi.
Rozmarra Se Jodiye
Science yaad rakhne ka sabse aasan tareeka hai use roz ki cheezon se jodna. Pressure cooker kaam kaise karta hai, fridge thanda kaise karta hai, LED bulb kam bijli kyun leta hai, nimbu khatta kyun hota hai — jab concept kisi asli cheez se juda hota hai to wo bhoolta nahi.
Exam mein bhi aksar aise hi application-based question aate hain, seedhi definition nahi.
Aksar Poochhe Jaane Wale Sawal
Class 11 aur 12 ki Science bhi padhni hai?
Zyadatar exams ke liye nahi. SSC, Railway, police aur MTS jaise exams ka Science Class 10 tak ka hota hai. Sirf kuch technical posts mein aage ka level maanga jaata hai. Apne exam ke previous year papers dekh kar level ka andaza lagaiye.
Arts background se hoon, Science samajh nahi aati.
Competitive exam ka Science factual hai, technical nahi. Aapko formula derive nahi karne, sirf facts yaad rakhne hain. Class 6 se shuru kijiye — ek mahine mein aap comfortable ho jaayenge.
Roz kitna time dena chahiye?
Shuruaat mein roz 45 minute se 1 ghanta, jab tak NCERT poori na ho jaaye. Uske baad roz 15 se 20 minute revision kaafi hai. Science ek baar bana lene ke baad sirf dohrane ka kaam rehta hai.
Aage Kya Padhe
Baaki GK portion ke liye Static GK Topics aur Current Affairs Ki Taiyari padhiye. Jin exams mein Science ka sabse zyada weightage hai unke liye Railway RRB Guide dekhiye.
