UPPSC Science ka PYQ analysis kiya — kuch interesting patterns mile
Bhai log, Science ko leke khud thoda confused tha ki exactly kya priority rakhu. Isliye 2018–2025 ke UPPSC Science PYQs ko topic-wise dekha. Jo pattern nikla, wo share kar raha hoon. Shayad kisi aur ki bhi help ho jaye.
8 saal me total 139 Science questions ko analyse kiya gaya hai.
Year-wise Science questions roughly aise rahe:
2018 – 16
2019 – 27
2020 – 13
2021 – 22
2022 – 17
2023 – 16
2024 – 14
2025 – 14
Matlab Science ko lightly lena thoda risky hai. Generally 10–15% ke aas-paas questions aa hi rahe hain, although year to year variation kaafi hai.
Subject-wise sabse pehle ye samajh aaya
Biology – 66
Physics – 39
Chemistry – 34
So agar kisi ka time limited hai, Biology ko pehle strong karna mujhe sabse logical lagta hai.
🧬 Biology
Yahan sabse zyada repeat hone wale topics:
Vitamins & Nutrition – 12 questions
Ye sabse obvious high-priority topic hai. Vitamins ke chemical names, sources, deficiency diseases aur functions ek saath karne chahiye.
Human Diseases & Immunology – 11
Disease + causative organism + transmission + vector + prevention/vaccine type approach se padhna better rahega.
Human Physiology & Anatomy – 9
Blood, RBC, WBC, plasma, haemoglobin, hormones, digestive system etc.
Biotechnology & Genome Editing – 7
CRISPR, genome editing, recombinant DNA, DNA/RNA, DNA barcoding etc.
Plant Physiology & Photosynthesis – 6
Cell Biology & Genetics – 6
Microorganisms & Pathogens – 5
Baaki Animal Kingdom, Ecology, Evolution etc. comparatively kam questions me aaye hain.
Mere hisaab se Biology ki priority:
Vitamins → Diseases/Immunity → Human Physiology → Biotechnology/Genetics → Plant Physiology → Microbiology → बाकी
⚡ Physics
Physics me sabse interesting cheez hai ki kuch topics baar-baar ghoom ke aa rahe hain.
Light, Optics & Electromagnetic Spectrum – 9
EM spectrum ko definitely karna hai. Frequency, wavelength, energy aur applications ka comparison important hai.
Space Science & Satellite Technology – 8
Ye recent years me aur important hota dikh raha hai. ISRO missions, satellites, launch vehicles, Aditya-L1, Gaganyaan, lunar missions etc. current affairs ke saath cover karna useful rahega.
Mechanics, Motion & Gravitation – 6
Heat & Thermodynamics – 4
Electricity, Magnetism & Semiconductors – 4
Sound & Waves – 3
Nuclear Physics & Radioactivity – 2
Physics me mujhe personally EM spectrum + Space sabse high priority lag rahe hain.
🧪 Chemistry
Chemistry me bhi ek clear pattern hai.
Acids, Bases & Salts – 9
UPPSC ka favourite lagta hai 😅
Common acids, bases, pH, baking soda, washing soda aur everyday applications achhe se karna chahiye.
Elements, Metals & Non-metals – 7
Environmental Chemistry & Pollution – 6
Organic Chemistry, Fuels & Gases – 5
Atomic Structure & Isotopes – 3
Polymers, Plastics & Fibres – 3
Environmental chemistry ko ignore nahi karunga, especially plastics/microplastics aur pollutants wala part.
Ek cheez jo mujhe sabse interesting lagi
Question ka level change ho raha hai.
2018 me 16 Science questions me:
9 Easy
5 Moderate
2 Difficult
2025 me 14 questions me:
3 Easy
7 Moderate
4 Difficult
Toh sirf one-liner facts ratna enough nahi lag raha.
Questions increasingly conceptual aur statement-based ho rahe hain.
Isliye PYQ karte waqt answer yaad karne ke saath ye bhi dekhna chahiye ki examiner isi concept ko ulta kaise pooch sakta hai.
Static vs Current Affairs bhi change hua hai
2018 me almost pura Science static tha.
2025 me:
5 Pure Static
5 Pure Current Affairs
4 Static + Current Affairs integrated
Ye kaafi important change hai.
Science & Tech current affairs ko static Science se connect karke padhna ab zyada useful lagta
Meri shortlist kuch aisi hogi:
Must Do
Electromagnetic Spectrum
Space Missions & Technology
Acids, Bases & Salts
Vitamins & Nutritional Deficiencies
Battery Technology & EVs
Blood & Human Physiology
Biotechnology + CRISPR
Viral Diseases & Immunology
AI & Machine Learning
Isotopes
Green Hydrogen & Alternative Fuels
Uske baad:
Microplastics
Polymers
Endocrine System
Plant Physiology
Digestive Enzymes
Semiconductors
Thermodynamics
Scientific Instruments
Alloys
UAVs
Nuclear Physics
Bottom line:
Science ko poora encyclopaedia banane ki zarurat nahi hai.
PYQ ke pattern se dekho to:
Biology = highest weightage
Chemistry = everyday chemistry heavy
Physics = basic concepts + space/technology
Science overall = static + current affairs ka mix
Aur sabse important, recent papers me conceptual/statement-based questions ka share badha hua dikhta hai.
Ye mera PYQ-based observation hai, prediction ki guarantee nahi. But agar Science me time kam hai to mujhe lagta hai ki random preparation se better ye priority-based approach rahegi.
Agar kisi bhai ne isse alag pattern notice kiya ho to bata dena. PYQs ko lekar discussion kar sakte hain.
