General Awareness
VIBGYOR for Classical Dances — Remember 8 classical dances: BMS-KOM-OK (Bharatanatyam, Mohiniattam, Sattriya, Kathak, Odissi, Manipuri, Kathakali, Kuchipudi). Learn origins: Kerala=3 (Mohi/Katha-kali), Tamil Nadu=Bharata, Assam=Sattriya.
Padma Award Hierarchy — Ascending order: Shri → Bhushan → Vibhushan (think "Shri is entry, Vibhushan is victory"). Bharat Ratna stands alone above all, max 3/year.
Nobel Prize Memory — PEPLMC: Peace, Economics, Physiology/Medicine, Literature, Physics, Chemistry. Economics added last (1968), not original. Peace & Literature decided by Norway & Sweden respectively.
Commonwealth Games → Asian Games → Olympics — Scale ladder: Commonwealth (smallest, 4-year cycle, odd years after Olympics), Asian Games (medium), Olympics (largest). Remember CWG years: 2010+8n pattern.
Reasoning Ability
Direction Sense: NESW Clock Rule — Visualize clock: N=12, E=3, S=6, W=9. Right turn = +90° clockwise, Left = -90°. If facing North and turn right, you face East (12→3 on clock).
Blood Relations Gender Trap — "No gender assumption": Sibling/cousin/parent can be any gender unless specified. Doctor/Engineer/Teacher = gender-neutral. Watch for "only son" or "only daughter" clues.
Dice Opposite Faces Sum — Standard dice: opposite faces always sum to 7. So 1↔6, 2↔5, 3↔4. If two faces shown, third visible face + hidden faces can be calculated instantly.
Coding Pattern: +1 Next Letter — A=1, B=2...Z=26. For position-shift: CAT → if +1 shift → DBU. Quick check: C(3)+1=D(4), A(1)+1=B(2), T(20)+1=U(21).
Syllogism: No → Some Not Conversion — "No A is B" converts to "Some B are not A" (valid). "All A are B" converts to "Some B are A" (valid). Draw Venn circles for complex statements.
Mirror Image: LEFT ↔ RIGHT Rule — Only horizontal inversion occurs. Letters symmetric on vertical axis (A,H,I,M,O,T,U,V,W,X,Y) look same. Asymmetric letters flip: b↔d, p↔q.
Quantitative Ability
Divisibility by 11 — (Sum of odd-position digits) - (Sum of even-position digits) = 0 or multiple of 11. Example: 1331 → (1+3)-(3+1)=0, divisible.
Percentage-Fraction Quick Converts — 12.5%=1/8, 16.67%=1/6, 33.33%=1/3, 66.67%=2/3, 87.5%=7/8. Memorize these for instant calculation without calculator.
Profit/Loss Base Confusion — Profit% always on Cost Price; Discount% always on Marked Price. If SP > CP = profit; if SP < CP = loss. Never mix bases.
LCM × HCF = Product Rule — For two numbers: LCM(a,b) × HCF(a,b) = a × b. Find any three, calculate fourth instantly. Works only for two numbers.
Time-Speed-Distance Triangle — Draw triangle: Distance on top, Speed and Time at bottom corners. Cover what you need: D=S×T, S=D/T, T=D/S. Finger-cover method.
Compound Interest Shortcut — For 2 years: CI - SI = (SI × R)/100, where R=rate%. For 3 years: CI - SI = SI × R/100 × (300+R)/100. Saves calculation time.
Average Addition Formula — When new number joins: New Average = Old Average + (New Number - Old Average)/(New Count. If 10 students avg 50, 11th scores 72: New avg = 50+(72-50)/11 = 52.
Geometry: Angle Sum Polygon — Interior angle sum = (n-2) × 180° where n=sides. Each exterior angle of regular polygon = 360°/n. Triangle(180°), Quadrilateral(360°), Pentagon(540°).
Hindi and English Language
FANBOYS Conjunctions — Coordinating conjunctions: For, And, Nor, But, Or, Yet, So. Connect independent clauses with comma before FANBOYS: "I ran, but I missed the bus."
Sandhi Types: 3 Main — SVV: Swar (vowel+vowel), Vyanjan (consonant rules), Visarga (ः changes). Example: देव+आलय=देवालय (Swar); सत्+जन=सज्जन (Vyanjan).
Active-Passive Tense Rule — Subject-Object swap; verb changes: is/am/are+V3 (present), was/were+V3 (past), will be+V3 (future). By introduces original subject: "Ram writes" → "is written by Ram."
Samas Quick Types — DBKTBAB: Dwandwa (समाहार), Bahubrihi (अन्य-पदार्थ-प्रधान), Karmadharaya (विशेषण-विशेष्य), Tatpurush (परपद-प्रधान), Avyayibhav (पूर्वपद-प्रधान). Most common: Tatpurush (second word dominant).
Muhavare Body Parts — आँख=pride/sight (आँखें दिखाना), हाथ=control (हाथ धोना=lose), मुँह=face/reputation (मुँह काला करना). 70% idioms use body parts—learn patterns.
Haryana — General Knowledge
Haryana Formation Date — 1-11-1966 (1st November). Remember as 111966 or "One-one-Sixty-six." Carved from Punjab on linguistic basis; Chandigarh shared capital.
Haryana's 6 Divisions — AFGHJR: Ambala, Faridabad, Gurgaon (Gurugram), Hisar, Jhajjar, Rohtak. Total 22 districts under these 6 administrative divisions.
Major Crops: 3W+BCS — Wheat, Bajra, Barley (rabi); Cotton, Sugarcane (kharbi). Haryana ranks #1 in Basmati rice export contribution, #2 in wheat production nationally.
Panipat's 3 Battles — 1526 (Babur vs Ibrahim Lodhi), 1556 (Akbar vs Hemu), 1761 (Marathas vs Ahmad Shah Abdali). Remember as 1-5-6: 1526, 15(56), 17(61)—add 30, then 205 years gap pattern.
Saraswati Civilization Sites — BRM: Banawali (Fatehabad), Rakhigarhi (Hisar—largest Harappan site in India), Mitathal (Bhiwani). Rakhigarhi rivals Mohenjo-daro in size.
Computer Knowledge
HTTP vs HTTPS — S = Secure (SSL/TLS encryption). HTTPS uses port 443, HTTP uses 80. Padlock symbol in browser = HTTPS. Banking/payment sites must use HTTPS.
